CHAPTER VII. 



THE FACE. 



THE parts of the face, other than those already 

 dealt with, will be considered under the following 

 lueads : (1) The face generally ; (2) the parotid 

 region ; and (3) the upper and lower jaws and parts 

 connected with them. The lips will be considered 

 with the "cavity of the mouth" (chap. viii). 



1. The face generally. The skin of the face 

 is thin and fine, and is more or less intimately adhe- 

 rent by a delicate subcutaneous tissue to the parts 

 beneath. The skin generally is very freely supplied 

 with sebaceous and sudoriparous glands, and hence 

 the face is very commonly the seat of acne, an erup- 

 tion that specially involves the sebaceous follicles. It 

 happens from the thinness of the skin, and from the 

 absence of dense fasciae, that facial abscesses usually 

 soon point and seldom attain large size. 



The cellular tissue of the face is lax, and readily 

 lends itself to spreading infiltrations, so that in 

 certain inflammatory affections the cheeks and other 

 parts of the face may become greatly swollen. In 

 general dropsy, also, the face soon becomes " puffy," 

 the change first appearing, as a rule, in the lax tissue 

 of the lower lid. The skin over the chin is peculiarly 

 dense and adherent to the parts beneath, and in most 

 respects closely resembles the integument of the scalp. 

 When such parts of the integuments of the face as 

 cover prominent bones, such as the parts over the
