302 DERMOID SYSTEM 



Q. Are the organic vital properties of the dermoid tex- 

 ture sympathetically affected? 



/?. They are; as when cold drinks check, or warm 

 fluids taken into the stomach, increase perspiration. 



Q. Whence the most usual excitant of these passive 

 cutaneous sympathies? 



Jl. They most frequently arise from the mucous mem- 

 branes of the stomach; but they often proceed likewise 

 from the lungs. 



Q. What are the active sympathies of the papillae? 



*#. When vpmiting or syncope follow, tickling, you 

 have an example of an active cutaneous sympathy. 



Q. How do the organic forces of the dermoid texture 

 excite active sympathies? 



.#. These sympathies are produced not by translation 

 of morbific matter, nor by the repercussion of fluids, but 

 by exciting the predominant vital forces of the sympa- 

 thizing organs. 



Q. Give an example of this. 



#. In inflammation of the thoracic serous membrane, 

 the perspiration is checked by cold. What does this mean, 

 but that the organic vital forces of the external capillary 

 tissue of the skin are altered; a sympathetic impression is 

 made on the organic forces of the exhalents of the pleura; 

 these last, which only admit serum in health, are placed 

 in relation to blood, and inflammation takes place. 



Q. At what season of the year are the organic forces of 

 the dermoid texture most exalted? 



ft.. In the hot seasons; hence the active sympathies are 

 then most prevalent, and most to be dreaded. 



Q. How is it that the active cutaneous sympathies vary 

 in different persons?
