DERMOID SYSTEM. 



/#. They are seated in the capillaries of the reticular 

 and teguments external to the chorion. 



Q. How are the cutaneous textures affected by dis- 

 tention ? 



v#. In great distention, the fibres of the chorion are 

 torn and separated; folds and wrinkles also arise from this 

 cause. 



Q. What effect has chronic disease on the skin? 



Ji. It deranges the dermoid texture, rendering it rough 

 and sallow. 



Q. What division of the causes of erysipelas do you 

 make? 



#. They are external and internal, or extrinsic and 

 constitutional. 



Q. Where is erythema or erysipelas seated? 



/2. In the reticular texture; the chorion is unaffected. 



Q. Is the chorion always sound in erysipelas? 



*#. In some cases the intense phlogosis affects that part 

 of the skin, and even the subjacent cellular texture; and 

 in these cases there is phlegmon, with great erysipelatous 

 tension. 



Q. What is the nature of the pain in erysipelas? 



Ji. It is an acute but burning pain. 



Q. Where is erysipelas most violent and dangerous? 



./?. On the head and face. 



Q. Why is this?
