*08 DADD'S VETERINARY MEDICINE AND SURGERY. 



»f mine, located in a cattle-raising district in the State of Main*, 

 informed me that this disease, accompanied by enlargement, often 

 prevail? there enzootically, and that most of the animals thui 

 affected die. I have had considerable experience in the treatmenl 

 of such affections in horses, but, as I have just observed, the result 

 is very unsatisfactory. I believe I have but one case cf cure on 

 record, and the medicines used on tliat occasion were stimulants 

 and tonics, with forty grains of iodide of potass per day. Tho 

 spine was also rubbed, night and morning, with equal parts of 

 cod-liver oil and spirits of camphor. 



Enlargement of the Spleen. 



SyrijAoiiis. — The symptoms of enlargement of the spleen in 

 horses (they do not differ much in cattle) are as follows: Feeble 

 pulse ; respiration not much disturbed ; the tongue is usually 

 coated; mouth, hot, and the breath has a feted odor; the mem- 

 branes lining the mouth and eyeballs have a slight yellow tinge; 

 the head droops, and the tips of the ears and lower part" of the 

 limbs are chilly; the patient is rather unwilling to move, and, 

 when urged to do so, exhibits a staggering gait, and sometimes falls 

 never to rise; the urine is scanty, and, in the last stages, blood 

 ooze's from the anus and nostrils ; colicky pains attend the disease. 



In a case that terminated fatally, I made the following record 

 of the post-mortem examination : On opening the abdominal cav- 

 il y, the spleen was found to occupy a very large space. It was 

 of immense proportions, and weighed nearly twelve pounds. The 

 ordinary weight is three pounds. It presented the appearance 

 of a spleen in the chronic stage of disease, being altered in struo- 

 ti're, of a dark, pitchy color, and surcharged with dark, venous 

 bl >od. Before death, I percussed the left side, in the locality of 

 thf spleen, and the sound elicited was of a solid character, which 

 indicated enlargement of the same. 



Tlie early symptoms of splenic apoplexy do not differ much 

 from the above, only they are of a more acute character. In the 

 lattei stages, the mak ly is complicated with a painful affection of 

 the bowels. The diagnostic symptom of splenic apoplexy, witL 

 enlargement of the same, is a notable enlargement on the left side 

 of the abdomen, well up toward the ribs. When standing behind 

 an affected animal, and casting one's eyes carefully along the 

 sides of theabdomina' walla, a perceptible eminence will be s<en.
