GELA'SIMUS, a genus of Brachyurous Crustaceans. [OCYPODIANS.] 



GELATIN, an animal substance composed of Carbon, Hydrogen, 

 Oxygen, and Nitrogen, found present in all parts of the body, and 

 constituting the walls or external investment of the cells of which 

 animals are composed. 



Amongst the component parts of all organised bodies the most 

 frequent is the cell. Modified in an infinite variety of ways, it gives 

 rise to the innumerable varieties exhibited both by plants and animals, 

 in the external form, the structure, and consequently the functions of 

 their organs. In the vegetable kingdom the substance employed in 

 the construction of these cells is cellulose combined with a little 

 protein. In the animal kingdom it is gelatin. The case is very simi- 

 lar, although the elementary form of the tissue and its chemical 

 characters are different, In animals we must distinguidh between the 

 persistent and the original cellular substance. The original in nil 

 probability varies in different cases, while the persistent exhibits a 

 constant and general character. The persistent tissue is consequently 

 a secondary product, and in this respect diners from the cellular sub- 

 stance in plants, which is a primary or original one ; neither has it
