The Latent Proportional Parts Table in Ordinary Interpolation

Ordinary interpolation is probably used more widely than any other process in arithmetic, save only the fundamental ones of addition, subtraction, multiplication and division. The object of this paper is to point out the presence, in every logarithm table, of a hidden subsidiary table of proportional parts. This may be called the Latent Table of Proportional Parts. Its use is recommended with all logarithm tables not equipped with auxiliary tables of Proportional Parts, as it saves time without producing unusual errors.

Explaining the Construction of Logarithm Tables to 3rd Formers and a Note on e

Whether it is because of the utility aspect or whether it is because of some other reason, boys are invariably interested in logarithms. Whenever I take up the subject with a form, at least one boy will ask: “Please, Sir, how were logarithm tables constructed?” When a master is confronted with this question, he usually thinks of logarithmic expansions, and he is obliged to tell the boy that the explanation is beyond his understanding.

The Coefficients of Stirling's Series for Log Γ(x)

where cm ()m Bm/ [(2m 1) (2m)], obviously requires for its evaluation adequate approximations to the numerical values of log 27, log x and cm. The desire to apply this series to the extension of my table' of 1/n! (r(n + 1) = n!, n integral), for higher values of n led to the original calculation2 of log r to 214 significant figures, to the computation of two 137place tables of natural logarithms for factors of the form 1 ^ a 10b, and finally to the calculation of the table of coefficients (cm) presented below. Incidentally the table given by Duarte3 is insufficient for my purposes because it was only designed to furnish about 42 significant figures. This table also has the disadvantage of greatly increasing the number of figures to be written in solving many problems because it is founded upon the base 10 instead of e.

Early Logarithmic Works

READERS of J. Henderson's bibliography of logarithmic tables (“Tracts for Computers”, No. 13, Cambridge, 1926) will be aware of the interest attached to Ezechiel de Decker's “Tweede Deel vande Nieuwe Tel-konst” (Gouda, 1627), in which was first published the important de Decker-Vlacq table of 10-decimal logarithms of numbers from 1 to 100,000. After the existence of this work had been doubted by many authorities, a complete copy was found at Utrecht by van Haaften in 1920.

Chemistry

THIS book provides a suitable course in volumetric analysis for the higher school certificate examinations. Thus an account is given of the preparation and use of standard solutions of acids, alkalis, potassium permanganate and dichromate, iodine, thiosulphate, and silver nitrate in neutral and acid solution. A concise and clear explanation is also given of the theory of indicators, including adsorption indicators. A useful feature of the book, especially from the point of view of scholarship candidates, is the list of practical problems at the ends of the chapters. Atomic weights, tables of logarithms and an index are given at the end of the book.

Tables for Statisticians

IN my review of “Statistical Tables”, by Fisher and Yates (NATURE, September 23, p. 533), I referred to the “interesting innovation of providing mean differences for half the interval only”. Dr. L. J. Comrie has pointed out to me that this practice is followed in E. V. Huntington's “Four Place Tables of Logarithms and Trigonometric Functions”, and I gladly take the opportunity of acknowledging this fact.

Science News a Century Ago

Baron de Prony, 1755–1839 ON July 29, 1839, the distinguished French mathematician and engineer, Gaspard-Claire-Francois-Marie-Riche, Baron de Prony, died at Asnières, near Paris, at eighty-four years of age. For many years he had been the senior member of the Corps des Ponts et Chaussées and was famous both as a writer and a constructor. Born near Lyons on July 11, 1755, he had been trained under Perronet, “the Telford of France”, at the École des Ponts et Chaussées, and afterwards became his assistant. With Perronet, too, he visited England. During the Revolutionary era, Prony formed one of the commission entrusted with the reformation of the French weights and measures and with the great survey of France. In connexion with this he organized and trained a body of computers for forming the logarithmic tables required, the result being seventeen large volumes of tables, afterwards deposited in the Paris Observatory. In 1798 he was raised to the rank of inspector-general in his corps and soon afterwards succeeded Chezy as director of his old school.
