He was from his early days much interested in botany, and 

 made some fine collections in the neighbourhood of Darjeeling, 

 partly in places which had not, or only incompletely, been ex- 

 plored before. He contributed his rarer plants to Kew, not 

 a few turning out to be new to science, among them Treutlera 

 msic/nis, Hook, f., a new genus of Asclepiadaceae. 



His own herbarium of Sikkim plants, about 700 specimens, 

 was acquired for Kew on his death ; other sets are at Petrograd 

 and Berlin.

August Ehiedeich Leopold Weismann was born on January 17, 

 1834, at Erankfort-on-the-Main. His father was Professor of 

 Classical Philology at a " Gymnasium " in that city ; his mother, 

 a refined, artistic woman, possessed considerable talent in music 

 and ]:)ortrait-painting. Their quiet home-life was a united and 

 very happy one. Weismann was the eldest of four children, who 

 were brought up simply and strictly ; he always spoke of his 

 parents with great admiration, holding them up to his own 

 children as examples ; and he himself retained his simple and 

 unassuming habits to the end of his life. 



As a boy, AVeismann was a keen collector of insects and plants, 

 and later showed leanings towards Chemistry and Physics, but on 

 practical grounds, it was decided that he should study Medicine. 

 With this object he went, in 1852, to Gottingen, and at the 

 close of his course published his Inaugural Dissei-tation on a 

 chemico-physiological subject. In 1856-7 he acted as assistant 

 in the clinical hospital, and then as chemical assistant at
