PROCEEDINGS OF THE SOCIETY. 999 



Mr. Conrad Beck exhibited and described a new form of portable 

 Microscope in which the Jackson-Lieter form of stand was retained. 



Mr. J, Mayall, jun., exhibited a Microscope having a modified 

 form of rack and pinion adjustment, in which what was known as the 

 " stepped-rack " principle had been adopted (see p. 958). It consisted 

 in making use of a triple rack with three pinions on one axis, which gave 

 a remarkable degree of smoothness of motion without the slightest ten- 

 dency to slip. This form of rack was used on a large scale in the beds of 



entered the army as as.>isfant-siirgeon, August 5, 1S()1 ; became captain and 

 assistant-siu-geon, July 28, 1866; major and surgeon, June 26, 1876. "For 

 faithful and meritorious services during the war " he received the brevets of 

 captaiu. major, and lieutenant-colonel, U.S. Army. 



He was assigned to duty in this Office May 19, 1862, and from that date until 

 the beghiuing of the illness which terminated in his death was intimately 

 identified with its professional and scientific work. 



While the valuable results of his life's labour are comprehended in a lono- list 

 of miscellaneous publications, both professional and scientific, too familiar to the 

 corps to require individual mention, his greatest triumphs were won in the field 

 of microscopical investigation in uormal and pathological histology, and in his 

 happy application of photo-micrography to the purposes of science. In these 

 pursuits he attained remarkable success, and achieved an enviable, world-wide 

 reputation, leaving to science and medicine lessons of undoubted value and 

 usefulness. Of his strictly professional work, the medical portion of the 'Medical 

 and Surgical History of the War of the Kebelliou ' was the crowning achieve- 

 ment. In the second part of this work he developed the results of lils careful 

 investigations into the nature and pathology of the intestinal diseases which had 

 proved so fatal in the late war. Here also he displayed his wonderful capacity 

 for that minute and exhaustive research which forms so striking a feature of his 

 writings. 



As in the case of his co-labourer, Otis, he yields to other hands the honour of 

 completing his labours. 



In addition to his engrossing professional duties, his restless activity of mind 

 led him to seek recreation in his favourite studies, physics, art, and philosophy. 



Endowed with a retentive memory and of untiring industry, he acquired a 

 vast store of information, which he held available for use at will ; lluent of 

 speech, he took delight in the expression of his views and opinions both in social 

 converse and in the arena of scientific debate. 



His fund of knowledge, his strong convictions, his tenacity of opinion, and 

 his quick perception made him a controversialist of no low order. 



With such a record, it is needless to s^jcak of his zeal, his ambition or his 

 devotion to his profession, and especially to the reputation of the corps of' which 

 he was so bright an ornament. 



Of a sensitive, highly strung, nervous organization, the confinement, anxiety 

 and labour to which he was subjected in his attendance upon the late President 

 Gai-ficld during his long illness, proved too much for a mind and body already 

 overstrained by incessant labour, and precipitated the illness which finally 

 terminated hLs life. 



At the time of his death Dr. Woodward was a member and Ex-Prcsidcnt of 

 the American Medical Assfjciation, a member and Ex-President of the Washino-ton 

 Philosophical Society, a member of the National Academy of Science, of°the 

 As8f)ciution for the Advancement of Science, of the Academy of Natural Sciences 

 of Philadelphia, and of the College of Physicians and Surgeons of Philadelphia. 

 He was an honorary member of several American and foreign scientific, medical' 

 and microsfopiciil societies, and the recipient of many distinguished honours 

 from Icarix'd bodies in this country and abroad.
