CORPORA CAVERNOSA VAGINA.

— 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 who have 

 borne many children, its length diminishes, and its breadth 

 increases in inverse proportion with its length. —
