ACONITE ROOT SALEP MANNA HEMP. 187 



CAMPHOR OF BLUMEA GRANDIS, D.C. Some pounds of it are i87i. 

 desirable, in order that its nature may be investigated. (See 

 ' Pharmacopoeia of India/ p. 128.) 



MISHMI BITTER, or MISHMI TITA. The small yellow rhizome 

 of Coptis Teeta, Wall., a drug known in medicine since a remote 

 period, is produced in the Mishmi. mountains to the east of 

 Assam, and probably also somewhere on the confines of China 

 further north. The plant which yields it is very little known, 

 and complete specimens are desirable. It is possible that some 

 second species may furnish a portion of the drug. 



ACONITE ROOT has been imported in considerable quantities 

 from India. In what district is it collected, and from what species 

 of Aconitum ? 



AROMATIC BARKS, known as CULITLAWANG, MASOY, and 

 SINTOC, derived from trees of the order Laurinece, are objects 

 of considerable trade in the Indian Archipelago. The traveller 

 should embrace the opportunity, when it occurs, of seeing the 

 bark collected, and of obtaining authentic specimens of it, and of 

 the tree yielding it. Masoy Bark is produced on the west coast 

 of New Guinea. 



SALEP. The tubers of several species of Orchis and Eulophia 

 are collected and sold in India under the name of Salep. It is 

 desirable to ascertain what species of Orchidaceous plants 

 furnish this substance, especially in the Himalayas and in 

 Cashmere. 



MANNA. It has for many years been asserted that a kind of 

 manna is produced in the East on a species of Tamarisk. It 

 requires to be determined whether any oriental Tamarisk yields 

 a saccharine substance of the nature of manna, and whether it 

 is collected, and where. 



HEMP. A very rough but tenacious hemp is produced in 

 Northern India, at Kangra, and elsewhere, and bears the name 

 of "Kangra hemp" or " Himalayan hemp." Is this the produce 

 of Cannabic Sativa, of which there is some doubt?
