 Holly bush, which attains the size of a small tree, is inserted 

 in this list rather as a stimulating medicinal plant than as a 

 substitute for the ordinary Tea plant, although in its native 

 country it is very extensively used for this purpose. From 

 the province of Parana alone there were exported more than 

 36 million pounds in 1871, besides 9 million pounds used for 

 home consumption ; while in Rio Grande de Sul the local pro- 

 vincial consumption is nearly four times as much, not counting 

 large quantities consumed by the aboriginal race. It is 

 cheaper than coffee or tea (about 5J. per pound), and an indi- 

 vidual there uses about 1 Ib. per week. It has a pleasant 

 aroma, and can- be taken with milk and sugar. It is the 

 favourite beverage in large portions of South America (Dr. 

 Macedo Scares) , The leaves destined for the Mate are slightly 

 roasted. I. Dahoon and I. dipyrena are used for the same 

 purpose, and probably other hollies may be found equally 

 good. Chemical principles : coffein, quina acid, and a pecu- 

 liar tannic acid, which latter can be converted into viridin 

 acid.
