sented as remedies in the " Formulario on Guia Medico, do 
Brazil" This work is compiled by Dr. Chernoviz, and is 
as replete with information and as carefully prepared as any of 
a similar kind in other languages. It in fact answers the pur- 
pose of a Pharmacopoeia in Brazil, and to it we shall refer as 
each article is presented.

pearance. The colour is reddish. The surface is somewhat 
rough and cracked. When broken, it is beautifully clear and 
transparent, and resembles gum Senegal. It is perfectly odor- 
less, and has a mucilaginous slightly starchy taste, like tra-
