By the death of Professor J. H. van't Hoff, which took 

 ■place at StegHtz, near BerHn, on March ist, the world of science 

 has lost one of its most brilliant investigators and careful and 

 inspiring teachers. All who have had the privilege of working 

 under the direction of Professor van't Hoff will bear testimony 

 to the wonderful inspiration given by association with him, 

 whilst his course of lectures on physical chemistry, given at the 

 University of Berlin, will always be remembered, not only for 

 the breadth of treatment, but also for the simple and clear 

 manner in which they were delivered. 



Jacobus Henricus van't Hoff was born in Rotterdam, on 

 August 30th, 1850. At the age of nineteen he entered the 

 Polytechnicum at Delft, and after passing through the techno- 

 logical course, proceeded to the University of Leyden, con- 

 tinuing his studies later in Bonn, under Kekule, and in Paris, 

 under Wurtz. After a very short career as docent, van't Hoff 

 -was appointed professor of chemistry at the University of
