DERMOID SYSTEM. 



Jl. It cleanses it from saline and oily matter. It may, 

 in certain cases, increase or diminish the vital forces of the 

 skin, but it does not alter its texture. 



Q. At what season is bathing most useful? 



t/?. In summer, when exhalation is greatest and most 

 compound. 



2. Paris common to the. Organization of the Dermoid 

 System. 



Q. Does cellular texture abound in the chorion ? 



#. It does, in great abundance. The chorion may be 

 considered as a sponge, the interstices of which are filled 

 with cellular texture. When the chorion has lost its cel- 

 lular texture it is like a sieve. 



Q. Do acute diseases affect the texture of the chorion ? 



fl. They do not; they attack its cellular tissue. The 

 chorion is disorganized in elephantiasis. 



Q. Does the cellular texture of the chorion extend to 

 is external surface beneath the epidermis? 



J2. The fact that granulations do not arise when the 

 epidermis is destroyed would induce the belief that there 

 is no cellular substance on the external surface of the 

 chorion; because, wherever there is cellular substance, 

 there you will see granulations, when the cellular texture 

 is laid bare. 



Q. There are two sets of absorbents on the chorion, 

 name them. 



ft. Those which arise from the chorion and return its 

 materials to the blood, and those which absorb foreign 

 substances through the epidermis.
