At Buitenzorg he l.ad established tlie ' Laboraton;e des Savants 

 etran-ers'— what a wealth of meaning and of scientihc hosp.tali y 

 is in that phrase -and at Tjibodas, already famous as the early 

 station for Cinrhona culture ux Java, he had a small mountain- 

 garden established, with a laboratory in close connection vyith the 

 vir<^in forest. At his instigation, the Government set apart 

 a portion of the original forest, so that it might remani un-

Treub left Java in October 1900, hopnig to spend the 

 remainder of his life in Europe, lie broke his journey at Lan-o, 

 and afterwards travelled to the Eiviera. But after 29 years 

 service in Java, cooler regions did not restore his strength, and on 

 the 3i-d October, 1910, he breathed his last at St. Eaphael. lie 

 was elected a Foreign Member, 5: h May, 1887. _ 



This brief sketch of a full and strenuous life gives no idea ot 

 Treub's charming personalitr. Even to those who met him only 

 durino- his occasional visits to Europe he was a dehghttul com- 

 panion, but to those who had the good fortune to visit him at 

 Buitenzorg he was still more ; he had a unique position, and used 

 it wisely and well. We have lost a great man, ot a character 

 too rarely found, and the present generation may never again see 

 his equal, but his memory will live with those who were fortunate 

 enough to know hiui and to value his labours at their true 



worth. ^1 , /-.i • 1 >
