DERMOID SYSTEM, 



susceptibility to increased sanguineous fulness in the 

 face? 



#. That in cutaneous diseases, especially variola, the 

 face is most violently affected. The affections of this re- 

 ticular tissue of the face are indicative in many cases of 

 internal visceral disease. 



Q. Repeat the two anatomical divisions of the reticular 

 capillary system. 



t#. That which contains the colouring teint, and that 

 which affords the fluids of transpiration. 



c. Of the Papillse. 



Q. What do you mean by these? 



Jl. They are small eminences arising from the external 

 chorion, which pierce the reticular surface, and become 

 contiguous to the epidermis. 



Q. What are apt to be confounded with these papillae? 



<ft. Certain cellular, vascular, or nervous bunches, or 

 sebaceous glands, which are lodged in the small oblique 

 canals, terminated by the openings of the chorion under 

 the epidermis. These bunches or bundles, or eminences, 

 are observable on the outside of the arms, and on the 

 back. 



Q. What occasions the petechiae of adynamic fevers ? 



t#. Extravasation of blood in the cellular texture of the 

 small pores, which open on the exterior of the chorion, 

 to transmit the hair$ &c. This occasions these petechiae. 



Q. What is the structure of the papillae? 



#. Analogy supposes them to be nervous terminations, 

 but this analogy has not been sustained as yet by demon- 

 stration.
