REVIEW — PERCIVALL’S HIPPOPATHOLOGV. 
355 
In an account of the disorder as it occurred at one time in France, 
Mr. Lassange informs us that ‘ the horses attacked voided five 
or six pints of perfectly clear urine every hour/ 
“The quality of the urine is that of an urina potus. It 
is thin and aqueous, and perfectly transparent. According to 
Lassange 100 parts of it contain of water 98.0 ; of urea, ben- 
zoate, and acetate of potash, acetate of lime, chloride of sodium, 
and free acetic acid 1.5; and of mucus and sulphate of lime, 0.5; 
making it to differ from healthy urine, 1st, in containing a larger 
quantity of water (for healthy urine has but seven-eighths of wa- 
ter); 2dly, in the presence of acetic acid, which is in part free ; 
3dly, in the absence of any earthy carbonate, which in healthy 
urine abounds. 
“The treatment of these cases is in the majority rather diet- 
etic than medical. Strict inquiry must immediately be set on 
foot into the nature and quality of the food the horse is eating, 
as well as into the kind of water he is drinking ; one or both of 
which — unless any other cause can be shewn for the origin of 
his disorder — had better be immediately changed. Should the 
horse be attacked during the spring or summer season, a very 
desirable change would be from the stable to the grass-field ; or 
when this cannot conveniently be done, soiling may be practised 
with advantage. Should the water appear to be the cause, and 
there be no means, or very great difficulty of obtaining any other 
kind, we may put a piece of chalk in the pail with a view of neu- 
tralizing, or rendering less harmful, the noxious impregnation. 
“The medicines found most serviceable in this disorder are 
astringents and tonics. A ball I am fond of myself is composed 
of sesqui-carbonate of iron and prepared chalk, of each half an 
ounce, made up with syrup, and given once a day. Mr. Castley 
appears to have derived benefit from galls. Mr. Stewart speaks 
in laudatory terms of opium. He gives daily a ball consisting of 
three drachms of opium, and of catechu, gentian, and ginger, two 
drachms of each, made up with a little tar. 
Should Any fever exist, such medicines, of course, become 
inadmissible. In their place moderate blood-letting and purging 
must be practised. In case the urinary disorder outlive the fe- 
brile one — which it will not often be found to do — recurrence may 
be had to the opiate and astringent medicines/’
