spissated by continual boiling. This process furnishes Kassu, or most astringent 

 terra japonioa, which is black and mixed with paddy criu, husks, and other 

 impurities. After the nuts are- dried, they are put into a fresh quantity of 

 water, boiled again ; and this water being inspissated, like the former, yields 

 the best or dearest kind of catechu, called Goony. It is yellowish brown, has 

 an earthy fracture, and is free from the admixture of foreign bodies. 



Most of the betel nuts imported into China come from Java, 

 Singapore, and Pinang. Betel nut is not so generally used in the 

 South of China as among the Southern Islands, and in the north 

 of China it is a luxury, as the pepper does not grow freely there. 

 Formerly there was a considerable trade in betel nuts with the 

 Coromandel coast, from whence the natives brought back manu- 

 factured goods and other necessaries in return, but this has ceased 

 for i^ome time. The common price was 20,000 for a dollar. These 

 nuts are seldom imported into England, though they might be of 

 use as a dye in some manufactures. 



The natives of the East chew the fruit of Elate sylvestris, 

 (which is something like a wild plum), in the same manner as the 

 areca nut, with the leaf of the betel pepper and quick lime. 



The inner wood furnishes a kind of Catechu or Cutch, which 

 contains much tannin and is a powerful astringent. It is obtained 

 by the simple process of boiling the heart of the wood for a few 

 hours, when it assumes the appearance and consistency of tar. 

 It hardens by cooling, and when formed into small squares and 

 dried in the sun is fit for the market. 



The produce of Bombay is of uniform texture and of a dark red 

 color. That of Concan and other parts of India is of chocolate 

 color, and marked inside with red streaks.

Catechu is in extensive use in India tor tanning purposes, and 

 of late years it has entirely superseded madder in the calico works 

 of Europe for dyeing a golden coffee-brown, one pound of catechu 

 being found equivalent to six pounds of madder.
