Diathermy in Medical Practise

1921 Journal of the American Medical Association (JAMA)  
This atlas of arteries in situ is a welcome contribution to anatomic illustration. It shows the arteries throughout the body in twenty-one roentgenograms, of which two are so prepared that they can readily be converted into six cards for stereoscopic study covering all regions. Twenty roentgenograms were made from the body of a full term fetus after injection of the arteries. This was necessary because suitable adult material was not available. One roentgenogram was made from a soldier's hand,
more » ... a soldier's hand, amputated after the arm had been shattered by a shell. The clearness and definition with which even the small arteries and anastomoses stand out is a revelation of the possibilities of roentgen-ray photography. A brief text, tabular in character, is arranged for convenient reference in the study of the plates. Some features of the anatomy of the arteries which can be studied to especial advantage in these plates, and which will make the book appreciated, are the relative richness of arterial supply of different regions and structures, anastomoses and collateral circulation, and relations to bones and joints. Incidentally, the state of ossification of the bones at the time of birth is well shown. It is to be hoped that subsequent editions may be enlarged by the inclusion of a full series of plates repre¬ senting all the arteries of the adult. Surgeons will appre¬ ciate the atlas because the relations shown are accurate and reliable-qualities inherent in roentgenograms. Such plates might well be mounted and exhibited in dissecting laborato¬ ries so that the study of them might supplement dissection. Laboratory Course in Histology. This little manual, of 118 blank and 118 printed pages, represents the laboratory instructions already tried out in the course in histology at Columbia University. The blank pages are to permit modification or amplification of any part of the course, being intended for notes regarding supplemental material, either fresh or in special preparations, introduced by instructors. The printed pages contain directions for study of the sections issued to the classes at Columbia, with only enough description to secure proper orientation\p=m-\ the amount being necessarily greater in the part of the book devoted to the nervous system (sixty-three pages). The student's attention is guided and directed, but he is not told what he sees; rather, he is asked to see for himself, the idea evidently being that the power of seeing for himself is useful and necessary in a physician, that it merits cultivation, and that it is more worth having then a tendency toward passive reception of observations made by some one else. The prep¬ arations indicated are well selected and well arranged, and the content sufficient to meet the needs of medical students in the introductory required course in histology, provided the amplification suggested is utilized in the study of fresh mate¬ rial. The method requires good instructors, and should produce good results with students of capacity. Mental Disorders Briefly Described and Classified, with a Few Remarks on Treatment and Prevention.
