Left side: 



Supra-renal, kidney, renal vessels and ureter absent. 

 Genital apparatus — normal on right side : completely absent on 

 left side. 



Case III (Studies). Male. 

 Eight side: 



Supra-renal normal in situation; somewhat flattened in appear- 

 ance. 

 Kidney, renal vessels and ureter, absent. 



Left side: 



Supra-renal normal in size and position. 

 Kidnej^, ureter and renal vessels, increased in size. 

 Genital apparatus larger than normal on left side: totally absent 

 on right side. 



The points worthy of note may be recapitulated thus: 



(1) Absence of the supra-renal gland on one side does not appear 

 to be compensated by over-growth of the remaining organ. 



(2) Complete absence of the ureter is associated with complete 

 absence of the genital apparatus of the same side. 



(3) Presence of the ureter in any degree is associated with pre- 

 sence of the genital apparatus. 



(4) Diminution or absence of renal tubules is not associated with 

 corresponding abnormalities in the genital apparatus. 



My thanks are due to Dr. Craven Moore for allowing me to write 

 this note and complete his series of cases.
