A volume of 348 pages, with 537 illustrations. Published by Georg Thieme, Stuttgart. Second enlarged edition, 1956. Distributed in the United States and Canada by the Intercontinental Medical Book Corp., New York 16, N. Y. Price DM 29.70— ($7.00).This text on radiographic technic and positioning is the second edition of a handbook which has been found most usable in the x-ray laboratories of Europe. The descriptive matter is brief and precise, and is closely tied in with the illustrations, to which it is conveniently contiguous. The illustrations themselves are chiefly photographs arranged in triads consisting of a surface picture, a reproduction of a skeletal facsimile, and a roentgenogram. In most of the roentgenograms the bone appears white to correspond to the usual appearance on the viewing box.Only conventional views are considered, no verbiage being wasted on the one-shot-a-year procedures. The author's personal contribution to roentgen technic, the Schoen bridge, is frequently suggested as an accessory to positioning. This radiolucent wedge is well known for its usefulness.Following the principal portion of the book, which is on the skeleton, appear sections on arthrography, venography, arteriography, fluoroscopy of the lungs, examination of the gastrointestinal tract, and urinary tract studies. The methods of Martius, Guthmann, Caldwell-Moloy, and Thorns are included in the section on pelvimetry, but no mention is made of William Snow. The concluding pages deal with myelography, encephalography, and foreign-body localization.Article HistoryPublished in print: May 1957 FiguresReferencesRelatedDetailsRecommended Articles RSNA Education Exhibits RSNA Case Collection Vol. 68, No. 5 Metrics Altmetric Score PDF download

Inscriptiones Graecae, V. I: Some Afterthoughts

The miscellaneous notes on Spartan inscriptions, mainly of the Imperial age, which I have put together in the following pages deal chiefly with texts already published in the Laconian volume of the Corpus (IG V. I) which record the Cursus Honorum of individuals or lists of magistrates or other officials. For many of these I suggest textual improvements, and for some an approximate date based on prosopographical evidence. Moreover, in a few cases, I have been able to unite fragments published separately in the Corpus, or to recognise the nature of lists hitherto classed as uncertain.

The Chest.

Under the caption "The Chest" the author has presented in semiatlas form the whole story of pulmonary disease from a roentgen standpoint. To the medical man not experienced in roentgen diagnosis its 500 pages of highly illustrated material may be used as an inductive study course which will stand the test of future experience. The experienced roentgenologist will find it an excellently classified review. The point of view of the author is excellent. About 150 pages are first spent in describing and illustrating the physical basis for recognizing disease of the lungs by the roentgen rays. The following 250 pages make application of these principles to the great mass of pulmonary conditions most frequently encountered. The final 100 pages deal with the more rare or miscellaneous condition met with in the lungs, pleura, mediastinum and diaphragm. The book is well balanced in that the major stress is placed on the

Mr. J. G. Muddiman on ‘The Bloody Assizes’

It is not long since a book bearing almost the same title as the one before me now appeared under the aegis of a judge’s name; which, while it set out to give a clear and readable account of the Monmouth rising and its consequences, was a disappointment to the serious student because of its obvious Whig bias and lack of that chief essential of the judicial mind—the sense of balance. Judge Parry, moreover, was content to perpetuate many errors because they fitted in with his own conceptions, and I fear that, backed by the influence of his name and position, they have been strengthened in the mind of the casual reader.The present volume is unlike its predecessor in all but name; the whole aim and intention so different that in a sense the title is misleading. Mr. Muddiman is not really concerned at all with the rising itself, nor does he attempt to give us dramatic sketches of the characters connected with it; we find here no suggestion of the Walking Gentleman, the Low-Comedy Buffoon, or the Comic Villain, no tolerance for Oates or Tutchin, no special tenderness for Dissenters, and above all no bias against ‘Judge’ Jeffreys. Even the standpoint—and the book is written from the Tory standpoint on the whole—is one of reason, moderation, and restraint. In short, it is necessary to realise from the beginning that these pages deal less with opinions than with facts; and that, while Judge Parry aims at giving us his own New of the period and the personalities who played their parts in it, Mr. Muddiman is inquiring into the foundations on which our knowledge of that period and of those personalities is based.

Three New Cases of Myiasis in Man in the North of England. with a Survey of Earlier Observations by other Authors

The term “Myiasis” is generally used to indicate the presence of Dipterous larvae in the living body of man or other animals. “ The form of Myiasis most commonly met with in the United Kingdom,” writes Austen (1912), “is that of the alimentary canal, as the result of which living larvae or pupae, greatly to the distress and alarm of the patient, are discharged from the bowel. Cases of Myiasis of the nasal passages and frontal sinuses the external auditory meatus, the subcutaneous tissue, and the urinary passages are apparently of quite exceptional occurrence in the British Islands.” The following pages deal with three hitherto unrecorded cases, two of urethral and one of intestinal Myiasis.

XIV.—The Minimum System of Two Quadratic Forms in n Variables

The following pages deal with the simultaneous system of two general quadratic forms in n homogeneous variables. It is a special case of Gordan's Theorem which proves such systems to be finite, for the general projective group of linear transformations. While several works have dealt with the cases when n = 2, 3, or 4, nothing seems to have been written on the general case except a memoir in the year 1908. We continue, and simplify, the results there obtained, and now establish that(1) All rational integral concomitants of two quadratic forms in n variables and any number of sets of linear variables may be expressed as rational integral functions of (3n + 1) concomitants, and forms derivable by polarisation.(2) These (3n + 1) forms, called the H system, constitute a strictly irreducible system.This system is exhibited in §7 astogether with polars.The work is divided into three chapters: I §§ 1–4 is introductory notation, II §§ 5–17 provides a proof of these theorems, while III §§18–21 gives the non-symbolic and canonical forms of the results.

Time Measurement: an Introduction to Means and Ways of Reckoning Physical and Civil Time

IN this book the author has aimed at giving the rudiments of time measurement to readers possessing no previous knowledge of the subject. The first forty pages deal with the nature of time measurement and of the more prominent natural cycles (the year, the day) suitable for the purpose of measuring time. To assist the reader towards an exact understanding of the astronomical terms involved, the author insists upon the use of the globes and the armillary sphere, and describes in full detail a cheap home-made example of the latter instrument.

The Peculiar Functions of the Junior High School: Their Relative Importance

This is far from the first appearance in educational literature of material purporting to deal with the special purposes of the junior high school. It has even been preceded by writings which, like this one, bear upon the relative importance of certain factors or that have come to be associated with the new institution, a relative importance arrived at by compounding the judgments of a number of educational workers. Justification for adding to the literature of this sort is to be found in the fact that heretofore the factors or items have included a hopeless confusion of functions and features. In other words, earlier presentations have had the defect of failing to distinguish between the special purposes of the reorganization under consideration and the administrative devices and changes by means of which these purposes are to be achieved. The writer is convinced that progress toward genuine reform will be slow indeed until the distinction between purpose and means is clear in the minds of those responsible for the reorganization and that many of the quasiand pseudo-reorganizations so far effected are to be charged to the current confusion to which reference has just been made. The materials in the following pages deal with peculiar functions only, not with a mixture of functions and features.

The petrology of the North Sea Drift and Upper Glacial Brick-Earths in East Anglia

Summary The field-evidence distinguishing the Upper Glacial Brick-earths from the North Sea Drift was summarized upon p. 150 of the paper to which this is a sequel. The included boulders, colour, absence of lamination, stratigraphical relations, included masses of other beds, height above Ordnance datum and thickness, were shown to be of value as criteria. The foregoing pages deal with the petrological aspects of the two series of deposits which have been confused with one another. It is shown that the mechanical analyses of the two series are very different. This is indicated graphically by Fig. 6. The deposits of the Norfolk coast sections are, as would be expected, very variable in grade-composition. No possibility exists, however, of confusing them with Upper Glacial Beds. The latter deposits have been confused with the Norwich Brick-earth. Mechanical analyses of a number of samples of Norwich Brick-earth from a wide area show a remarkable conformity, being characterized by a high sand-grade and low clay-grade. The Upper Glacial Brick-earths conform to two types, ( a ) that of the blue earths with a high clay-percentage, and ( b ) that of the red earths with a high silt-percentage. In either case the gradecomposition is very different from that of the Lower Glacial deposits. (Fig. 6.) The detrital mineral residues do not provide us with a means of distinguishing Upper and Lower Glacial deposits from one another. This is doubtless largely due to the facts that abundant mineral material was brought in from all sources, and that the Lower Glacial deposits in part were ploughed up, and helped to make the later glacial beds. The mineral assemblage is unsurpassed in British sediments for variety and beauty (over forty mineral species, exclusive of varieties and cementing materials, being recorded). The detrital residues are characterized by the rich colour, large size and freshness of the grains. The magnetic minerals, which are coloured, preponderate, and yield beautiful pleochroic effects. The variety is only to be expected when the mode of origin of the deposits is considered. While in most sediments minerals derived from metamorphic rocks are most abundant, in the East Anglian Drifts a considerable amount of material occurs as a result of the disintegration of igneous rocks. Among other minerals, abundant apatite, amphiboles, epidote, hypersthene, dolomite, sphene and augite were thus derived. The small compound rock-grains in the Drifts serve to distinguish the Upper from the Lower Beds. In the former, sandstone, limestone, and shale chips from British Jurassic and Cretaceous rocks are plentiful, and yield evidence, supported by the presence of erratics, of the direction of ice-flow into East Anglia. The coarse grains of the North Sea Drift consist mostly of fragments of igneous and metamorphic rocks, of lydite-pebbles, Tertiary flintchips, coprolites, chalk-pellets, and shell-fragments.

The Basic Open-hearth Steel Process

NEARLY half this work is an elaborate chemical treatise on gas-producer practice, and the next ninety pages deal with the chemistry of slag-making and the heat equivalents of the oxidisable constituents charged into the furnace. The remaining portion treats of the various basic methods adopted, from the scrap and carbon to the ore and molten pig-iron processes.

VI.—A Further Contribution to a Comparative Study of the dominant Phanerogamic and Higher Cryptogamic Flora of Aquatic Habit in Scottish Lakes

This contribution is a continuation of a former paper on the same subject, references to which in this paper will, for the sake of brevity, be referred to as ante, p.…, or ante, fig.… The present pages deal especially with the following districts of Scotland:—1. North-west Kirkcudbrightshire.2. South-east Kirkcudbrightshire.3. Wigtownshire.4. Fife and Kinross.

V.—Rodents from the Pleistocene of the Western Mediterranean Region

In a former publication I have dealt with the anatomy of Prolagus sardus (Wagn.), from the Sardinian and Corsican Pleistocene, in comparison with that of its Tertiary relatives. The following pages deal with the geographical distribution of Pleistocene Prolagus and its bearing on more general questions.When Ouvier discovered, in the ossiferous breccia of Corsica, remains of a ‘Lagomys,’ which he believed to be closely related to the Siberian Lagomys alpinus, he also suggested other analogies between the faunas of the two regions—Siberia and Corsica (as well as Sardinia), and commented upon the supposed relationship between the insular Mouflon and the Siberian Argali. Similar views were expressed by B. Wagner.Pumpelly, Loeard, and Lortet sought to establish a connection between a supposed Corsioan ‘ice-age,’ as attested by the trace of ancient glaciers, and the former existence in the island of a supposed inhabitant of cold regions, the Lagomys corsicanus. Hensel had, however, shown before, in 1856, that the affinities of Lagomys sardus from the Sardinian bone breccia are not with the recent Lagomys (Ogotona), but with a Miocene type, for which he proposed the generic name Myolagus (antedated by Prolagus, Pormel). He was in consequence inclined to assume a Tertiary age for the breccias in which the Prolagus occurred (and, indeed, for the whole of the Mediterranean bone breccias). A similar view has again been brought forward of late years.I myself pointed out (1) that the Corsican Lagomys likewise belonged to the genus Prolagus, as indeed had already been suspected by Hensel from his inspection of Cuvier's figures; (2) that the Tertiary age of the Corsican and Sardinian breccias could not be upheld, above all, because the mollusca occurring in them, as Loeard bad shown to be the case in the ossiferous breccia of Toga, near Bastia, are still living in the neighbourhood.

The Chemistry of Plant and Animal Life

THIS is a text-book of a type which is not very satisfactory from an educational point of view, as being written to supply the needs of a special class of students. It aims at supplying the chemistry, both pure and applied, which will be required by a class of mature students taking a college course in agricultural science. No preliminary knowledge of chemistry is assumed, and the preface indicates that the work is to be completed in a session of six months with one class-room or laboratory exercise each day. In consequence, the contents range from instructions for bending glass tubes to an account of such debatable matters as the relation of gliadin and glutenin to the quality of wheat flour. It would be hardly fair to call the treatment superficial, but clearly the object of the book is not so much to educate the student as to supply him with a certain amount of information about the scientific side of practical matters, and particularly to put him into a position to follow the current investigations of the experiment stations. Of course, the task is an impossible one; no ordinary student can acquire a real knowledge of pure and agricultural chemistry in six, months, but given the special conditions, the book represents Prof. Snyder's abundant experience of trying to make the most use of the limited opportunity. The first 150 pages are devoted to ordinary inorganic chemistry, then about 100 pages deal with the proximate constituents of plants, followed by a section on the general course of development in the plant. Then come discussions of the composition of individual crops, and about eighty pages on digestion and the nutrition of animals. In the earlier part of the book a number of experiments are suggested, with a useful series of questions designed to make the student think out the object of each experiment.

VI. On the structure and affinities of matonia pectinata, R. BR., with notes on the geological history of the matonineœ

In describing an ascent of Mount Ophir—about fifty miles east of Malacca, in the Malay Peninsula—Wallace writes as follows : “ After passing a little tangled jungle and swampy thickets, we emerged into a fine lofty forest, pretty clear of undergrowth, and in which we could walk freely. We ascended steadily up a moderate slope for several miles, having a deep ravine on the left. We then had a level plateau or shoulder to cross, after which the ascent was steeper and the forest denser till we came out upon the “ Padang-Batu,” or stone-field, a place of which we had heard much, but could never get any one to describe intelligibly. We found it to be a steep slope of even rock, extending along the mountain side farther than we could see. Parts of it were quite bare, but where it was cracked and fissured there grew a most luxuriant vegetation, among which the pitcher plants were the most remarkable .... A few Coniferae of the genus Dacrydium here first appeared, and in the thickets, just above the rocky surface, we walked through groves of those splendid ferns, Dipteris Horsfeldii and Matonia pectin, which bear large spreading palmate fronds on slender stems, 6 or 8 feet high. The Matonia is the tallest and most elegant, and is known only from this mountain, and neither of them is yet introduced into our hot-houses.” A sketch of Dipteris and Matonia accompanies this description. Both these ferns are of special interest on account of their rarity and isolation at the present day, and as living representatives of generic types which had a wide distribution in Europe during the Mesozoic epoch. The following pages deal with the structure of Matonia pectinata and with such records of fossil ferns as throw light on the past history of Matonia and closely allied genera.
