superficially placed longitudinal groove. Apically, this 

 groove bifm-cates so that the clitoris here seems to consist 

 of three lobes, which at the apex are slightly free from one 

 another. The two grooves separating them pass backward 

 and downwards towards the ventral side of the clitoris, and 

 pass forward underneath, being gradually lost. Ventrally, 

 therefore, the clitoris also presents the appearance of being 

 divided into three lobes by two shallow grooves. 



The two main portions of the clitoris (looked at from 

 rbove) become widely separated cranially, and fuse with 

 the ventro-lateral wall of the cloaca. Arising between 

 these from the clitoris floor, and separated from the lateral 

 clitoris folds by somewhat deep grooves, which extend 

 vontro-laterally below the lateral clitoris folds, is a fold 

 which, being caudally weak and of no great height, on 

 being traced in a cranial direction, becomes considerably 

 stronger, but not so strong as the lateral clitoris folds. 

 Sections show that this fold is continuous with the median 

 apical lobe of the clitoris This fold splits anteriorly 

 into two divisions, separated by a deep narrow groove, 

 which, passing forward, loses itself in a very deep pouch. 

 downAvards into which also pass the folds enclosing it. 

 Into this pouch two other pairs of folds pass ; one pair is 

 continuous with two from the urogenital canal, and them- 

 selves secondarily fold.ed, lose themselves in the pouch. 

 Bounding the pouch laterally and passing into it is a pair 

 of transverse folds, one on each side. Each of these arises 

 from about half-wuv up the lateral side of the urogenital 

 canal, and forms a swollen fold of mucous membrane which 

 almost touches its fellow of the opposite side. The floor 

 of this pouch is much sunk below i lie general level cvf the 

 floor of 111? urogenital canal, and is considerably thinner. 



MICROSCOPIC STRUCTURE OF THE CLITORIS. 



The following account is based upon the examination 

 in serial sections of 15 micra in thickness, both transversely 

 and horizontally, of the clitoris in the virgin, and in an 

 old adult female with pouch young: — 



Immediately behind the apex of the clitoris, the rloacal 

 wall is raised into a median cloacal fold. This is separat- 

 ed from tho clitoris by a narrow but deep transverse 

 groove, curved in accordance with the shape of the apex 

 of the clitoris. Histologically this fold is found to be ex-
