These Hairs Now Blossom Whiter than the Swan

To the Editor:— Androgens have been, at least those strong ones, thought responsible for the growth of hair on the face and head of man and indeed, likewise, indicted for the bald top. To add more confusion I hereby submit the case history of a man proven to have prostatic cancer, and who, though he had been bald for many years, began to notice the return of hair during estrogen therapy after orchiectomies. A 58-year-old man with proven carcinoma of the prostate was first seen in October 1961. Bilateral orchiectomies were performed followed by a ten-day course of diethylstilbestrol (stilbestrol), 1 gm given intravenously daily. He was discharged and told to take chlorotrinisene, 12 mg daily. In March 1962, the chlorotrinisene was discontinued and diethylstilbestrol 5 mg three times daily was given. In December 1962, severe bone pain responded to another 14-day course of diethylstilbestrol. At this time noticeable new

Arsenic Toxicity With "High" Doses of Carbarsone

To the Editor:— Carbarsone, an organic pentavalent arsenical widely used as an amebicide, has been reported only infrequently as causing toxic reactions, 1,2 and these instances are usually mild. Our recent observation of two cases of severe toxic reaction prompts this communication. A 29-year-old white male, entirely well until the onset of amebic dysentery, was admitted with a two-day history of malaise, disorientation, irritability, and tonic-clonic seizures. Two days prior to admission he had completed a ten-day course of carbarsone, 250 mg four times daily. Other therapy included emetine, 1 grain daily for six days, and tetracycline, 250 mg four times daily for two days. Coma, hyperreflexia, and decerebrate posturing were present on admission. Lumbar puncture revealed a mild pleocytosis and a protein value of 434 mg/100 cc. An electroencephalogram showed diffuse cerebral dysfunction. After dimercaprol (BAL) therapy arsenic was found in the urine, and the patient recovered. A 27-year-old

From Nucleus to Universe

This book contains a series of lectures given in a ten-day course for science teachers at the University of Sydney. For the participants it will provide a quite excellent record of what must have been a particularly stimulating experience, and Professors Butler and Messel and their colleagues are to be congratulated on the initiative which brought together so strong a lecturing team.

Refresher Courses for Science Teachers

TERMINATION of a student's normal course of study often brings to an abrupt end his active connexion with the university. In the case of science teachers, this is particularly undesirable, for it is important that the rapid developments which are taking place in their subjects should be fully discussed between school and university teachers, especially in relation to teaching methods. With these considerations in view, a ten-day course on modern aspects of chemistry was recently held at the University College of North Wales, Bangor, in co-operation with the Welsh Department of the Board of Education, one of the inspectors of which, Dr. D. M. Williams, assisted in the organisation of the course. Summaries were given of recent work on atomic structure, valency theory and its application to problems concerning the structure and reactions of some inorganic and organic compounds, the electro-chemistry of solutions, and the chemistry of natural and synthetic products of special interest ; lectures and experiments were included illustrating advances in the theory and practice of pH determination, indicators, electrometric titrations, distillation, and chromatography, together with a demonstration of glass-blowing technique, a show of scientific films and a display of modern books, dealing especially with the subjects selected. While it was apparent that the teachers attending the course derived benefit and interest from it, the discussions proved most stimulating also to the University personnel who participated. The course was conducted by Prof. E. D. Hughes and Drs. W. R. Angus, I. Dostrovsky, J. Graham and D. R. Llewellyn, assisted in the experimental work by Dr. F. Brown, Mr. T. R. Jacobs, and senior research students ; Prof. C. W. Davies and Dr. W. C. Evans, of University College, Aberystwyth, gave special lectures.
