TANS. 



y. From Areca Catechu. 



Kasu from Ceylon, in circular flat cakes, like the Kauchoo of Dharwar, 

 but covered with paddy husks, and exhibiting white crystalline graina 

 internally. 



Besides the above, the following kinds are found in commerce : 

 a. From Acacia Catechu. 



1. Pale, and dull in square cakes, 2 inches long, 2 broad, and 

 1 deep, exported from Bahar, and Bengal. 



]8. From Nauclea Gambir. 



1. In cylinders, or discs, pale, dull pinkish in colour, and marked 

 with the impression of some coarse cloth. 



y. From Areca Catechu. 

 1 . Coury, much paler than Kassu. 



8. From undetermined sources. 



1. Brown Catechu in conical masses from Siam. 



2. Black mucilaginous Catechu ; probably Akakia, the extract of the 

 pods of Acacia arabica 



The following Leguminosse yield tans also : 



Acacia arabica. W. The bark. The pods also known to tanners 

 as Neb-neb, yield an astringent extract, sold in Bombay under the name of 

 Akakia. See " Drugs." 



Butea sps. The concrete exudation, being a kind of Kino. 



Ccesalpima coriaria, \V. of Cura9ao, Carthagena/and the West Indies. 



The pods, Libi-dibi, or Divi-divi, or Libi-divi. Grows luxuriantly in 

 Bombay. 



Ccesalpinia (Pnpai?}. The pods, Pipi. I find Pipi attributed to 

 C. Papai in popular books only. 



Cassia auriculata. Linn. Turwur of the Deccan. The seed 

 and bark. 



Mora excelsa, Walpers, of Guiana. 



Prosopis Algaroba^ of South America. The pods, Algaroba, or 

 Algarobilla. 



PterocarpUS marsupium, Box. The concrete exudation, 

 Kino. 



Many more of less value might be enumerated, but to attempt to 

 be exhaustive in the class of tans, \\ould almost double the pages of 

 this work, and I have therefore strictly confined myself to those which 

 are generally known.
