CORPORA CAVERNOSA VAGINA. 187 



In the virgin state at puberty, its length is about five 

 inches, and its breadth when moderately distended, one inch. 

 In a natural state of the parts, there is no cavity, the surfaces of 

 the mucous membrane being in contact. In women wh^have 

 borne many children, its length diminishes, and its breadth 

 increases in inverse proportion with its length.
