Another point worth noting was the specific gravity, which 
instead of being diminished as in the insipidus form was greatly 
increased, it being 1060. 
I have related this case not only to show that diabetes 
mellitus occurs in the horse, but also to record the subnormal 
temperature, which if it be constant, as already stated may be a 
most important factor in the differential diagnosis from diabetes 
insipidus. I would therefore suggest that more attention be 
paid to subnormal temperatures, from which I am sure there is 
a great deal to be learnt. 
I will be pleased to hear through the medium of your 
valuable paper if any practitioners have met with subnormal 
temperatures, and in what diseases.— Veterinary Record. 
HYDRO-THORAX. 
Hydro-thorax can only be regarded as a grave complication 
of disease of the pleura, and perhaps other organs, consequently 
any treatment which will prevent or remove it is well worth our 
serious consideration. In your issue of September 29th, 1894, 
Mr. Malcolm draws attention to a method of treatment adopted 
by him, viz., the administration of iodine, and asks for the 
experience of others. A brief account of a case which occured 
last November may prove interesting. 
Subject, a brown cart gelding, five years old, under treat¬ 
ment for pleurisy. Four days after its admission to the in¬ 
firmary signs of hydro-thorax were discovered, next day they 
were more pronounced, and on the sixth day the symptoms 
had become so aggravated that it was decided to relieve the 
dyspnoea by tapping, and also try the effect produced by the 
• administration of iodine. The operation was performed with a 
fine trocar and canula on the animal’s right side, and about five 
gallons of fluid abstracted. The fluid was of a dark straw colour, 
and when it flowed into the bucket caused a quantity of white 
froth, it was, in short, simply blood serum. 
As the tincture was the only form in which the drug was
