29/A.—Still improving. Appetite better—pulse 55, and respi¬ 
rations 17 per minute—physic purging. Continue the treatment 
of yesterday. From this date the old horse continued to recover, 
and in about fourteen days after the last date he resumed his 
work. The limb, however, never subsided to its proper size, but 
remained greatly enlarged so long as the animal lived For two 
years after the above the horse continued to labour as usual, with¬ 
out any intermission from disease, save now and then an attack of 
megrims; at the end of which time the infirmities incident to old 
age began to manifest their characteristics more fully : his eyes 
became amaurotic, and he was unable to rise when down without 
assistance, although the appetite and spirits continued as good as 
ever. It was deemed best, however, to have him destroyed, which 
was done by r dividing the carotid artery. From the extreme age of 
the animal, and from the peculiar attacks of disease to which he 
was subject, I determined to make a rough dissection of the carcass, 
which I proceeded to do immediately after he was dead. 
Dissection .—State of the digestive organs. The teeth, tongue, 
pharynx, esophagus, stomach (which was large and capacious), 
small and large intestines, were all remarkably healthy in appear¬ 
ance. The liver was firm in its structure, and dark in colour, 
and weighed sixteen pounds five ounce avoirdupois. A few large 
white worms were in the colon, but the whole of the digestive 
organs, to all appearance, were as perfect and as healthy as could 
be conceived. 
Urinary Organs .—The kidneys, ureters, bladder, urethra, &c. 
were also in appearance perfectly healthy. 
Muscular System —The muscles of animal life, so far as I 
examined them, were firm and healthy in their organization : the 
colour of them in some, I thought, was pale; but beyond this no 
further peculiarity (if a peculiarity it be deemed) was observable. 
State of the diseased Limb .—On the removal of the skin from 
the hind extremities, I at once observed a difference in the colour 
of the exposed structures. The faschia of the diseased limb was 
covered with a yellow coloured fluid, not unlike as though the 
tissue had been coated over with a quantity of bile, or very yellow 
serum. On cutting deeper, I perceived the areolar tissue to 
partake of the same colour, and a yellow liquor exuded from it: 
the tissue itself was also changed; it was dense, thicker, and 
partook more of a fibrous character than natural: this change was 
observable in all the areolar tissue of the limb, at least all that I 
examined. The lymphatic glands were greatly enlarged ; and on 
cutting into their substance, the knife met with considerable 
resistance. A scirrhous structure was exposed, the yellow fluid 
flowed forth in abundance, and on carefully exposing the vessels
