ACTION AND USES. 



The action and uses of cotton wool in medical and surgical 

 practice are sufficiently familiar. Absorbent cotton is now 

 much employed. 



Pyroxylin is introduced for the purpose of making collodion. 



Collodion, when painted on the skin or other exposed part, 

 instantly dries by evaporation of the ether, forming a fine film. 

 This film serves as a protective to thin, inflamed, broken, or 

 incised surfaces, preventing bed-sores, arresting haemorrhage 

 (as in leech-bites), and closing fissures or punctures made with 

 aspirateurs or trochars in paracentesis. The flexible collodion 

 does not contract on drying or readily crack, and is a better 

 form for most of the above purposes.
