GEORGE ENGELMANN. 519 



which he had for many years been specially investigating, " In 

 1880 he made a long journey through the forests of the Pacific States, 

 where he saw for the first time in the state of nature plants which he 

 had studied and described more than thirty years before. Dr. Engel- 

 mann's associates [so one of them declares] will never forget his 

 courage and industry, his enthusiasm and zeal, his abounding good- 

 nature, and his kindness and consideration of every one with whom 

 he came in contact." His associates, and also all his published 

 writings, may testify to his acuteness in observation, his indomitable 

 perseverance in investigation, his ci-itical judgment, and a rare open- 

 ness of mind which prompted him. continually to revise old conclusions 

 in the light of new facts or ideas. 



In the consideration of Dr. Engelmann's botanical work, — to 

 which these lines will naturally be devoted, — it should be remem- 

 bered that his life was that of an eminent and trusted physician, in 

 large and general practice, who even in age and failing health was 

 unable — however he would have chosen — to refuse professional ser- 

 vices to those who claimed them ; that he devoted only the residual 

 hours, which most men use for rest or recreation, to scientific pursuits, 

 mainly to botany, yet not exclusively. He was much occupied with 

 meteorology. On establishing his home at St. Louis, he began a 

 series of thermometrical and barometrical observations, which he con- 

 tinued regularly and systematically to the last, when at home always 

 taking the observations himself, — the indoor ones even up to the last 

 day but one of his life. Even in the last week he was seen sweeping 

 a path through the snow in his garden to reach his maximuna and mini- 

 mum thermometers. His latest publication (issued since his death by 

 the St. Louis Academy of Sciences) is a digest and full representation 

 of the thermometrical part of these observations for forty-seven years. 

 He apologizes for not waiting the comjDletion of the half-century 

 before summing up the results, and shows that these could not after 

 three more years be appreciably different. 



A list of Dr. Engelmann's botanical papers and notes, collected by 

 his friend and associate, Professor Sargent, and published in Coulter's 

 Botanical Gazette for May, 1884, contains about one hundred entries, 

 and is certainly not quite complete. His earliest publication, his 

 inaugural thesis already mentioned {De Anthohjsi Prodromus), is a 

 treatise upon teratology in its relations to morphology. It is a re- 

 markable production for the time and for a mere medical student with 

 botanical predilections. There is an interesting recent analysis of it in 

 " Nature," for April 24, by Dr. Masters, the leading teratologist of our
