INFLAMMATION OF THE SPLEEN (SPLENITIS). 



Acute inflammation of the spleen^ although there is no reason 

 to doubt its existence, I have not seen more than once or twice at 

 the most ; but chronic inflammation of this organ is I believe by 

 no means uncommon, having myself seen several instances, and I 

 know of one at the present moment in a Newfoundland dog, the 

 property of a friend : at least, from former cases which fell under 

 my observation, I conclude it so, and am pretty certain I am not de- 

 ceived. This dog had been subject to great confinement, not being 

 loosened from his chain for weeks together. He was received by 

 my friend with an unthrifty looking coat, but gorged with flesh : 

 the mischief, however, was done, and soon began to shew itself; 

 he became emaciated, while the left side of the abdomen remained 

 hard and protruded ; he continued to husk, and to have irregular 

 loose stools. These, in essential particulars, were the symptoms 

 exhibited in this instance during his life. After his death, indeed, 

 an examination of the body presented a mass of indurated and 

 disorganized thoracic contents. The heart also was much en- 

 larged ; and the spleen likewise. Indeed, the whole of the abdo- 

 minal contents were more or less indurated and swollen ; and 

 whenever a dog has been unthrifty in his coat, and irregular in his 

 evacuations, I have almost invariably found that both the liver 

 and spleen of the animal were thus diseased, particularly the latter: 

 but whether this was a cause or a consequence it was dijSicult to 

 determine. 



INFLAMED BLADDER (CYSTITIS). 



This is not a very common complaint among dogs, nevertheless 

 it now and then occurs: in the year 1810 there was an epidemic 

 prevalent, in which the bladder was in almost every instance very 

 much inflamed ; and in many of the cases which occurred it was 

 exclusively so. Cystitis shews itself by a very frequent pulse, 

 great restlessness, and panting: in some instances the urine is
