 Gildemeister and Hoffmann, The Volatile Oils, 2 nd edition, vol. HI, page 146. 



Chamomile Oil. — According to an English periodical 1 ), oil of chamomile is 

 a suitable solvent for platinum chloride. It is said to be used for this purpose in 

 the glass and porcelain industries, in order to coat vessels with platinum. 



Chenopodium Oil. — See Wormseed Oil, p. 80 of this Report. 



Cinnamon Oil, Ceylon. — The demand for cinnamon oil and, in a still higher 

 degree, for cinnamon leaf oil has increased considerably during the last years. The 

 latter can be obtained in a satisfactory quality from Ceylon, the Seychelles and 

 Mauritius, whereas it seems to be' impossible so far to distil a good bark oil from 

 raw material of other origin than Ceylon, although it is reported that cinnamon bark 

 from the Gold Coast has yielded in the last years valuable oils of agreeable odour 2 ). 

 The area planted with cinnamon trees in Ceylon has decreased continuously, as other 

 plants, like caoutchouc-trees and coconut palms pay better. The latest official estimate 3 ) 

 of the total area under cinnamon is about 35000 acres, as compared with 48000 acres in 

 1909. The cinnamon gardens of Ceylon are situated chiefly in the Southern and Western 

 Provinces of the island. The following tables give details of the exports from Ceylon: —
