The chief parts of the urinary apparatus are the kidneys^ 

 and the bladder : the ureters and urethra being but tubes 

 serving as conduits to the urine ; which by the former organs 

 is elaborated_, by the latter received and retained until such 

 time as shall become convenient for its ejection. The exemp- 

 tion of horses from venereal affections^ and their less liability 

 than men to generate calculous disorder, contracts the list 

 of their diseases of these organs : indeed, were it not for 

 injury — inwardly as well as outwardly inflicted — we should 

 probably hear but little of such diseases. Over-exertion 

 and strain, particularly under heavy burthens, is one grand 

 cause of renal disease ; medicine, and food possessing active 

 diuretic properties, constitute another; bearing all which in 

 mind, it will at all times become a leading desideratum 

 in the treatment, to take care to remove or avoid the re- 

 petition of such influences. The kidney of the horse is 

 a peculiarly susceptible organ : it is easily acted on ; and 

 many — indeed most — medicines we are in the habit of 



' In the ' Veterinarian' for 1835, mention is made of a horse having but a 

 single kidney. It was a glandered mare brought to the Veterinary School for 

 slaughter. The kidney was found at the entrance of the pelvis, situated rather 

 to the left side. Its form was that of the right kidney, and it was as large as 

 two ordinary-sized kidneys. (•Journal Theoretique,' 1835.)
