Schenk at Wiirzburg. Here, where the administration was in 
fullest accord with the desires of the great investigator, and 
where he received fullest recognition, Sachs remained thirty 
years, always hard at work. 
During his professorship at Wiirzburg, Professor Sachs 
declined calls to high positions at Jena, Heidelberg, Vienna, 
Dorpat, Berlin, Bonn, and Munich. At Wirzburg a great 
building, which had originally served to house a pharmacological 
institute, was placed entirely at his disposal for the uses of the 
botanical institute, since become famous throughout the botani- 
cal world, and inseparably associated with the name of its 
founder. Here were assembled rich collections, excellent con- 
trivances for teaching, and instruments without number, all of 
which bear eloquent testimony to the emphasis which its director 
laid upon instruction as well as investigation. ‘Give your chief 
attention to your lectures”? he wrote to me at Bonn in this 
connection. ‘‘Regard the activity of a professor in the way of 
publication as a thing of much value for its own sake, and the 
results as things not to be overlooked, yet always bear in mind 
that the professor is primarily a teacher.” In his laboratory 
Sachs gathered about him a group of young botanists chosen from 
the whole scientific world, and the ‘“ Arbeiten” of the institute 
became the recognized authority upon physiological research.

Only to those who possessed, like himself, the “ heilige Ernst” 
of their subjects were the privileges of the Institute extended. 
It was hedged about with such rigid restrictions that those who 
sought the world-renowned establishment for less commendable 
purposes were distinctly discouraged. Whoever neglected his
