JULIUS SACHS. 161 



one is charmed with our luxuriant vegetation, but there are 

 no signs of blossoms. It is as dark at four o'clock as it 

 would be at the same hour at Christmas, and it has been 

 like this for the last three weeks. I should not complain, 

 liking as I do to take things as they come, but unfortunately 

 I cannot live without sunshine and the lack of it makes me 

 ill." 



It was at Wiirzburg that Sachs first found fit opportunity 

 to develop his talent for teaching. Too often it happens 

 in lecture-rooms that " man viele sieht, die nicht da sind" but 

 this did not apply to him. His fascinating, lucid exposi- 

 tions stimulated the students, whilst he knew well how to 

 practically illustrate his subject. He worked incessantly at 

 the materials for demonstrating, drew and painted a number 

 of diagrams, and was constantly adding to his stock of dried 

 plants, alcohol preparations, models and cultures. He con- 

 sidered that all should be in due relation to the subject 

 matter in a scientific lecture as in the acting of a play. In 

 the winter he lectured on general botany (anatomy and 

 physiology) and in the summer on the " Natural History 

 of the Plant World ". Besides this he often gave experi- 

 mental demonstrations in the summer and this necessitated 

 a great deal of work ; occasionally he lectured on the history 

 of botany and on the physiological basis of morphology. 

 After 1874 he had a class every term for microscope work. 



A great number of botanists worked at one time or 

 another in his laboratory. The first were Gr. Kraus and 

 Millardet (both formerly at Bonn and Freiburg). Among 

 others attracted by him to Wiirzburg were, Baranetzky, 

 Brefeld, Francis Darwin, Detlefsen, Elfving, W. Gar- 

 diner, Godlewski, Goebel, Hansen, Hauptfleish, Klebs, H. 

 Muller-Thurgau, Moll, Noll, Pedersen, Pfeffer, Prantl, 

 Reinke, D. H. Scott, Stahl, Vines, De Vries, Marshall 

 Ward, Weber, Wortmann, and Zimmermann. He insisted 

 upon his pupils being in earnest about science, and he 

 brooked no laziness. Weak natures naturally felt his 

 influence most strongly, but he set a higher value on those 

 from he could gain something. 



With failing health he withdrew more and more into
