..X.. Foetus with tiQurinogenital s//stem. — This remarkable speci- 

 men, for which I am indebted to Mr Miles, was an eiglit-months', 

 foetus with no permanent anus, and no representative of external 

 genitals except a strap-like projection of skin from the pubes 

 about an inch long. 



On sagittal mesial section I found no bladder, only primitive- 

 gut ; a rudimentary allantois above the pubes, no internal 

 genitals, and no ureters or kidneys. 



I do not purpose discussing this remarkable case fully, but 

 merely point out that it justifies — 



(1) The consideration of the urinogenital organs as forming a 



correlated system. 



(2) The views of Lieberkiihu and Keibel as to the develop- 



ment and origin of bladder. 



These investigators derive it from the primitive gut, and only 

 its apex from the allantois. If in this case we had some early 

 destruction of Wolffian duct, it would account for the absence 

 of ureter and kidney. In some cases, however, a rudimentary 

 kidney has been noted by Ballantyne, and this points to the 

 kidney not being entirely a Wolffian duct derivative. The non- 

 division of the primitive gut into its rectal and bladder portions 

 is difficult to explain,

 - — This rare and, so far as I know at present, unique case 

 occurred in the practice of Dr Inch of Gorebridge. AVhen I 

 saw it with him, the child was a week old and was in every 

 respect healthy and normal, except that while it had the genitals 

 of a female child, there was attached to the skin surface between 

 anus and vagina what seemed to be a scrotum with an anterior 

 opening, into which a probe passed for a sliort distance. 



The annexed diagram (fig. 36) shows that the child had the 

 extertaaT. female genitals normally developed, except that the 

 preputium clitoridis was split into two halves. So far as I
