DIABETES IN A MARE* 
go to the hog-tub, and drink wash. At the end of autumn, she 
was taken fiom the mare, and put into the straw-yard ; there 
she had what water she chose to drink, but no notice was taken 
of her constitutional thirst. In the summer she was turned out 
to grass in a field well supplied with water. It was now that 
her owner first suspected she was not right; for whenever he 
was in the field, and stayed a short time, she was sure to drink 
freely. He thought it a singular thing, and particularly watched 
her; yet, on account of her healthy appearance, he never sought 
medical advice. She went on in this way until she was four 
years old, when she was taken into a loose box previous to 
breaking, and then the inconvenience of the disease was princi¬ 
pally felt. She voided urine in such abundance, as to com¬ 
pletely saturate the straw, and make the stable very uncomfort¬ 
able. Her proprietor was, in consequence of this, determined 
to part with her, and he sold her to a dealer; but she w 7 as soon 
returned. He afterwards exchanged her with a neighbouring 
farmer, and it was there that I first met with her. She was 
then six years old, very lean, but well shaped, and with such 
fine action, that I was induced to speculate about her. 
Before I commenced any medical treatment, I attended a few 
days to her diet: I gave in succession three pails full of water, 
and she drank the last as eagerly as the first. In about ten 
minutes she began to stale: the urine was as transparent and 
clear as the water she had drunk. After a short time, I gave 
her as much water as she would drink, and exercised her di¬ 
rectly afterwards; but water appeared to have no effect on the 
intestines, with regard to purging. 
I now gave her five drachms of aloes in solution, which ope¬ 
rated very well. I allowed her only three pails full of water in 
the day; but that appeared to be too small a quantity, and she 
would not eat sufficient of either hay or corn. The bowels be¬ 
came constipated, and I repeated the dose of aloes: it purged 
sufficiently, but left the mare debilitated. A few days afterwards 
she began to cough, and there was a soreness in the upper part of 
the trachea, and then came on a discharge from the nostrils, 
which was quickly followed by ulceration of the Schneiderian 
membrane, and symptoms of confirmed glanders : I then put an 
end to her existence. Since she had been in my possession, 
and I had had her two months, she could not have caught the 
disease from infection, and I believe it was generated in the 
system. 
Post mortem examination .—I opened the chest, and found the 
lungs in a bad state: there were tubercles and vomicae in abun¬ 
dance, more than I thought could have been there, considering
