RETENTION OF UEINE. 



accidents which may arise from neglecting 

 animals whilst in pain, &c. 



There are various remedies to apply for 

 the removal of the cause of retention, accord- 

 ing to the nature of the disease. When 

 possible, a warm bath should be given the 

 animal, and a dose of purgative medicine. 

 Warm water injections, the internal admi- 

 nistration of opium, in some cases attended 

 with severe spasm and pain, and the early 

 use of the catheter, are amongst the most 

 useful means to adopt to afford speedy 

 relief. 



Catheters have been constructed of leather 

 and metal, or of gutta percha, both for male 

 and female animals. 



For the horse a flexible tube about three 

 feet and a half feet in length, with a rounded 

 extremity, to pass freely through the ure- 

 thra, is usually employed in this country. 

 Hering says that he has left such a tube in 

 the urinary passages days and even weeks 

 without in any way injuring the organs. 

 The horse catheter invented by Professor 

 Brogniez, of the Bruxelles Veterinary Col- 

 lege, is a most convenient instrument. It a \ 

 is composed of a tube divided into a smaller 

 part about 11 inches in length, with a 

 rounded head about five lines in thickness. 

 The lesser portion is made .of a spiral wire 

 tube, covered by gutta percha. It is at- 

 tached to a thicker and less flexible tube 

 17 inches in length. A steel director with
