 stance. A few years later, Cleyer," who had a personal knowledge of 

 China, pointed out the enormous consumption of catechu for mastication 

 in the East, — that it is imported into Japan, — that the best comes from 

 Pegu, but some also from Surat, Malabar, Bengal, and Ceylon. 



Catechu was received into the London Pharmacopoeia of 1721, but 

 was even then placed among " Terrce medicamentosce." 



The wholesale price in London in 1776 was ^16 16s. per cwt.; in 

 1780 £20 j in 1793 £14 14s., from which it is easy to infer that the 

 consumption could only have been very small.^

an 



aqueous extract made from the wood of the tree. The process for 

 preparing it varies slightly in different districts. 



The_ tree is reckoned to be of proper ago when its trunk is about 

 a foot in diameter. It is then cut down, and the whole of the voody 

 part, with the exception of the smaller branches and the bark, is 

 chopped into chips. Some accounts state that only the darker heart- 

 wood is thus used. The chips are then placed with water in earthen 

 jars, a series of which is arranged over a mud-built fire-place, usually 

 in the open air. Here the water is made to boil, the liquor as it 

 becomes thick and strong being decanted into another vessel, in which 

 the evaporation is continued until the extract is sufficiently inspissated, 

 when it is poured into moulds made of clay, or of leaves pinned together 

 m the shape of cups, or in some districts on to a mat covered with the 



to the sun and air. The product is a dark brown extract, which is the 

 usual form in which cutch is known in Europe. 



In Kumaon in the north of India,^ a slight modification of the 

 process affords a drug of very different appearance. Instead of evapo- 

 rating the decoction to the condition of an extract, the inspissation is 

 stopped at a certain point and the liquor allowed to cool, " coagulate, 

 and crystallize over twigs and leaves thrown into the pots for the pur-
