CHAPTER I. 

 INFLAMMATION. 



INFLAMMATION may be aseptic or septic. A very large propor- 

 tion of inflammatory conditions are septic, that is, due to the 

 invasion of bacteria. 



The entrance of bacteria into the tissues may be through the 

 skin or mucous membranes, usually with more or less loss of 

 surface epithelium. When once the blood stream 'is infected, 

 there is a possibility for remote parts of the body to become 

 inflamed, because the bacteria may be carried to them in the 

 circulation. 



Exposed surfaces of skin are liable to injury, and thus an 

 entrance for micro-organisms is obtained. Hence it is that 

 septic inflammation of the head, of the upper part of the neck, 

 and of the hands and fingers is so common. 



Inflammation of the cornea or conjunctiva is frequent, 

 and is due to the irritation caused by minute foreign bodies 

 entrapped between the eyelids and the external surface of the 

 eyeball. The rhythmical contraction of the orbicularis palpe- 

 brarum is intended to prevent this inflammatory process by the 

 removal of extraneous matter, but it is not always successful. 



Other parts which, though usually covered by clothing, are
