the Embryo. The first of these structures, that is, the epi- 

 carp, mesocarp and endocarp, belong to the fruit or berry, 

 the other three, that is, the testa, albumen and embryo, being 

 essentially parts of the seed or bean. The uses of these 

 various structures surrounding the embryo are to protect 

 it from injury and at the same time supply it with proper 

 nourishment until such time as it is enabled to take care of 

 itself The testa or silver-skin enveloping every part of 

 the albumen, following and dipping into the furrow on 

 the face of the Coffee bean bjr its tough, leatherly nature, 

 acts as an effectual protection to the delicate structures con-

 cocoanut, and the aromatic, ruminated secretion t the 

 nutmeg. It is a secretion, found in the internal of the 

 seed, enveloping the embryo plant, and for the support 

 of which it is destined when it first begins to germinate. 

 Each perfect Coffee berry should contain two such
