DISEASES" OF THE URINARY ORGANS. Ill 



is also occasionally observed in the horse and the ox. It 

 sometimes appears as an epizootic. It is generally announced 

 by anxiety, agitation, trembling of the hinder limbs, frequent 

 attempts to urinate, vain efforts to accomplish it, the evacua- 

 tion small in quantity, sometimes clear and aqueous, and at 

 others mucous, laden with sediment, thick and bloody : 

 escaping by jets, painfully and with great difficulty, and then 

 suddenly rushing out in gfea:t quantity. To this list of 

 symptoms colic may often be added. The animal drinks with 

 avidity, but seldom eats much, unless at the commencement 

 of the complaint. The skin is hard and dry, he looks at his 

 flanks, and his back and flanks are tender when pressed upon. 



" During the latter part of my connection with Mr. Blaine, 

 this disease assumed an epidemic character. There was a 

 very great drought through almost every part of the country. 

 The disease was characterized by general uneasiness ; con- 

 tinual shifting of the posture ; a tucked-up appearance ; an 

 anxious countenance ; a quick and noisy pulse ; continued 

 panting ; the urine voided in small quantities, sometimes 

 discharged drop by drop, or complete stoppage of it. The 

 belly hot, swelled, and tender to the touch ; the dog 

 becoming strangely irritable, and ready to bite even his 

 master. 



" ist May, 1824. — Two dogs had been making ineffectual^ 

 attempts to void their urine for nearly two days. The first 

 was a terrier and the other a Newfoundland. The terrier was 

 bled, placed in a warm bath, and an aloetic ball, with calomel, 

 administered. He was bled a second time in the evening, 

 and a few drops of water were discharged. On the following 

 day the urine slowly passed involuntarily from him ; but 

 when he attempted to void any, his efforts were totally 

 ineffectual. Ballis composed of camphor, puW. nva ursi, 

 tinct. ferri mur., mass purg., and pulv. lini. et gum arab., 

 were administered, morning, noon, and night. On the 5th 

 the urine still passed involuntarily. Cold lotions were 

 employed, and tonic and, astringent medicines administered,
