issued in 1869, "svas a pioneer and long remained the standard work in 

 English upon that subject. 



Doctor Caldwell brought to his life work a broad and thorough 

 training, gained at the Lawrence Scientific School of Harvard and 

 the universities of Gottingen and Heidelberg. He received his doc- 

 tor's degree from the former institution in 1857, being a student of 

 the famous Wohler at the time when the latter was at the height of 

 his career. Returning to this country he was for a year assistant in 

 chemistry at Columbia, professor of chemistry, physics, and botany 

 at Antioch College, in Ohio, from 1859 to '62, and professor of 

 chemistry in the Pennsylvania Agricultural College from '64 to 

 '68. The interval between '62 and '64 was spent in the service of 

 the United States Sanitary Commission. He was called to Cornell 

 in 1868, being the first professor appointed in that institution, and 

 remaining in active service for thirty-five years. 



"\"Mien the Cornell University Agricultural Experiment Station 

 was organized in 1879 he was elected director, and the three reports 

 published by the station contained many papers by him upon the 

 results of fertilizer exjjeriments, feeding experiments with cows and 

 on maintenance rations for steers, the influence of feed on the compo- 

 sition of milk, sugar-beet culture, and methods of agricultural analy- 

 sis. WTien the station was reorganized in 1887 he became chemist, 

 and continued in that office until his retirement in 1902. 



It was as a teacher quite as much as an investigator that Doctor 

 Caldwell contributed to the advancement of agricultural science and 

 practice. To a large number of students he opened up the needs and 

 jDOssibilities of agricultural investigation and gave an inspiration to 

 enter that field in the search for truth. Upon these he impressed an 

 intelligent appreciation of the requirements of that work, especially 

 the necessity for thoroughness and exactness in plan and method at 

 every stage of the undertaking. Although not active for several 

 years past, owing to failing health, his work has been continued in 

 the students who have gone out from his instruction into experiment 

 station work, and who have carried to it the zeal and the love for 

 truth which he imparted.
