sound, they may afterwards put forth new shoots. However, 

 the appearance of this insect does not seem to be the primary 

 cause of the disease of the trees, — on the contrary, disease is

 plants, but was undoubtedly indigenous to Java. 



Altogether there were, in May, 1858, upon the whole island 

 three quinquina plantations, which have been specially estab- 

 lished with a view to the solution of certain questions of 

 climate at A^arious elevations, and are situated in the follow- 

 ing localities : — 



1. In Tjipodas at the foot of Gunung Gedeh (4100 to 

 4800 feet above sea-level), in a beautiful Liquid-ambar forest, 

 and containing 80 plants. 



2. In Bengal enzong, on the declivities of the Malabar 

 Range (4000 to 7000 feet in height), in the midst of a con- 

 siderable oak forest [Quercus fagifoUa)^ containing 600 plants. 



3. South of Besuki on the Ajang Range (about 6800 feet 

 above sea-level), in a plantation* containing 21 plants, to 

 which Dr. Junghuhn gave the name of AYono Djampie, i. e. 

 Forest of medicines. 



* According to our latest advices from Java, which extend to November, 1860, 

 there are at present in the Preanger Regency upwards of 100,000 China plants in the 

 very best order, so that this valuable commodity not only may be regarded as fully 

 naturalized in that island, but the Dutch Government even complied with the request of 

 the British Government for a certain number of seedlings for introduction into India.
