What to do. — Spread fresh litter under the horse to induce him to pass 

 the urine ; give warm water injections and antispasmodic drenches, such 

 as No. 50 ; gentle pressure on the bladder per rectum is sometimes suffi- 

 cient, but 1)0 very careful not to overdo it for fear of rupture. Pass the 

 catheter up the penis if necessary ; in the case of a mare all that is neces- 

 sary is to insert one finger into the neck of the bladder. 

 VII. Kupture of the Bladder. 



Causes. — This only occurs in females during parturition when the 

 bladder has failed to be emptied before the labor is begun, and in cases 

 of long continued spasm of the neck of the bladder — especially, if by fre- 

 quent repetitions of the spasms the walls of it have become weakened 

 and flaccid. 



How to know it. — Nervous trembling of the whole body ; accelerated 

 pulse ; cold extremities ; nausea ; abdominal pain that runs on to inflam- 

 mation and causes death, or the animal dies from the nervous shock. 

 Examination per rectum finds the bladder empty and flaccid ; introduction 

 of the needle of a hyi^odermic syringe, or a small trocar into the median 

 portion of the belly, will let out urine which is readily recognized by the 

 odor. 



Nothing can be done. 



VIII. Diabetes Insipidus or Profuse Staling. 



This is a superabundant drain of water from the system through the 

 kidneys. 



Causes. — Excessive and long continued use of diuretics in acute dis- 

 eases, especially lung troubles ; acidity of the stomach and chronic indi- 

 gestion, causing much thirst, so that great quantities of water are drunk. 

 Musty hay and kiln dried oats are frequent causes. 



How to know it. — By the excessive thirst ; profuse staling, flooding the 

 stall ; the urine is copious in quantity, frequently voided and as clear as 

 water. Emaciation and hidc])ound soon follow. The appetite is capri- 

 cious ; the coat staring ; slight fever; inclination to lick the walls and 

 mortar to get lime, and to eat the bedding in preference to clean, fresh 

 food. There is weakness, and palpitation of the heart. 



What to do. — Give one or two doses of the following recipe : 



No. 71. 1 Drachm iodine. 



y^ Dnichni iodide of potash, 



Powder and mix with linseed meal to make a ball.
