its adoption in other stables will lead to similar cures in many 
an invaluable hunter or hack. Sir Peter Laurie kindly allows 
any one to see this most useful arrangement, any day, at his 
stables, Park-square Mews, Regent’s Park. — The Illustrated 
London News, 1 5th November, 1851. 
*** The above reminds us of a man who professed to “ cure 
crib-biting” by having the horse, the subject of it, for some time 
in his own stable ; the manger of which was so contrived that 
the moment the crib-biter seized hold of it, it fell, or sprung from 
his grasp, to the ground. This so alarmed the horse that he 
became afraid to repeat the act, and thus for a time had the ap- 
pearance of being “ cured” of his evil habit. The objection to 
Sir Peter Laurie’s device is, that it is at the very time when 
horses are eating their corn that they are apt to crib-bite the 
most, which, we apprehend, his horse must do whenever the 
shutter is withdrawn. This is enough to keep the bad habit in 
memory, so that the animal does not lose although he cannot 
practise it as usual. — Ed. Yet. 
ON THE EXISTENCE OF SUGAR IN THE URINE OF 
A HORSE. 
By Dr. X. Landerer. 
Diabetes is a very rare disease among horses. The animals 
which are affected with this disorder pass much more urine than 
they do in a state of health, and even more than the quantity of 
water which they drink. The urine is almost colourless, as clear 
as water, and throws down no precipitate. It has not the usual 
characteristic odour. The animal loses flesh from day to day, 
his appetite fails, and he wastes away. Having observed that 
this disease very much resembles diabetes in the human sub- 
ject, I subjected the urine of a horse thus affected to chemical 
investigation. The specific gravity was 1.048. By evapora- 
tion I obtained a thick syrupy mass. With yeast it commenced 
to ferment briskly, and disengaged carbonic acid. The other 
re-agents used for the detection of sugar, namely, sulphuric acid, 
chromic acid, the method of Heller with caustic potash, &c., 
convinced me of the presence of sugar, and I am sure that the 
malady of this horse was a true diabetes mellitus. — Pharma-
