330 PROCEEDINGS OF THE AMERICAN ACADEMY 



Notwithstanding his constant investigations, Professor Clark found 

 time to prepare a course of lectures of a thoroughly philosophical 

 and general nature, which were delivered before the Lowell Institute 

 in the winter of 1864. These were subsequently rewritten, and ap- 

 peared in the form of a book, under the title of " Mind in Nature," 

 in 1865. 



It is evidently the work of a student capable of handling the entire 

 animal kingdom ; and the three hundred and fifteen octavo pages are 

 crowded with original observations, clearly and distinctly stated in a 

 popular and readable form, and illustrated by four hundred and twenty 

 drawings, one hundred and forty of which are original. 



Professor Clark was appointed to the chair of Zoology in Pennsyl- 

 vania Agricultural College in the year 1866, where he remained only 

 three years, exchanging it for similar duties in the University of Ken- 

 tucky, at Lexington, in 1869. 



Neither of these situations was agreeable to his tastes, owing mainly 

 to the pressure of collegiate duties, which prevented him from follow- 

 ing out abstruse investigations. He therefore accepted with great 

 readiness the offer made him, in 1872, of the chair of Veterinary Sci- 

 ence in the Agricultural College of Massachusetts. Here his duties 

 were of a more congenial nature ; and he had applied himself with 

 renewed energy to the formation of a museum of comparative anatomy, 

 when his labors were interrupted by his final sickness. 



The personal qualities of Professor Clark wei'e of a kind to endear 

 him to many friends, especially to those students who sought and 

 obtained from him counsel and advice in their studies, as the writer did 

 on many occasions. His uniform courtesy of manner, though often in 

 ill-health ; his unswerving devotion to scientific pursuits, though for 

 years laboring under pecuniary difficulties, — are worthy of the highest 

 praise a biographer can bestow. 



He has earned by his labors a right to be classed as one of the 

 closest and ablest of the zoological observers, and as the finest and 

 most experienced microscopist which this country has yet produced. 



John Bachman was born February 4, 1790, in Ehinebeck, Dutchess 

 County, N Y, He was descended from an old German family, who 

 originally came to this country at the time of William Penn. At the
