18 THE AMERICAN NATURALIST. [VoL. XXXIII. 
In 1892 Dr. Baur was called to the University. of Chicago as 
assistant professor of comparative osteology and paleontology, 
and three years later was advanced to an associate professorship 
in the same institution. Here he bent all his energies to 
developing the department of which he had charge. For the 
purpose of increasing the paleontological collections of the 
university two expeditions were sent out, one to eastern 
Wyoming, in charge of Dr. Baur himself, and a few years later 
another to Texas, in charge of Dr. E. C. Case. Besides the 
work on the material collected on these expeditions, his turtle 
monograph, and the Galapagos material, Dr. Baur spent much 
time in working out elaborate courses of lectures on vertebrate 
osteology and phylogenetics. His classes were never large, 
owing partly to the advanced and highly specialized nature of 
the subjects presented and partly to his inability to express 
himself in a clear and attractive manner in the English language. 
Incessant work along so many different lines wore on his highly 
nervous organization. During September, 1897, his friends 
feared that his mental health was giving way, and he was 
persuaded to go abroad, in the hope that a year’s sojourn with 
his relatives in Munich and southern Tyrol might restore him 
to health. His illness (general paresis) was not dispelled by 
the change. It was found necessary to transfer him to an 
asylum, where he soon succumbed, June 25, 1898. He was 
buried at Munich. Prof. v. Kupffer, who helped to equip the 
young scientist for his brief but brilliant career, placed the 
merited laurel wreath upon the grave. Very near Dr. Baur 
reposes George Ebers, who died a month later. 
Such was Dr. Baur’s external and uneventful life; his true 
inner life was one of constant and enthusiastic investigation, 
which is but imperfectly indicated in the list of his published 
works appended to this article. The hundred and forty odd 
papers bequeathed to science are only a prodromus of the greater 
things which he hoped to accomplish in the near future. Like 
Professor Cope, whom he greatly admired and whose successor 
in herpetology he had hopes of becoming, he possessed a very 
active mind and wide interests. That he was always busy with 
= a number of problems simultaneously is shown by a perusal of
