The horse has had water twice to-day: he drank about a bucket- 
ful and a half altogether. I give him as much as he will 
drink. 
Dear Sir, — I WROTE to you about ten days ago, acknowledging 
the receipt of your’s of the 2 1st ult., in which you desired that I 
would let you know how Mr. Smith’s horse was going on. I then 
stated that I thought the emaciation was attributable entirely to a 
morbid action of the kidneys. My opinion is quite confirmed now 
as to that. The disease has been hanging about him for more than 
six months. The iodine has done no good, as the thirst still con- 
tinues. His appetite is not at all what it should be ; he there- 
fore does not get into such condition as I should like. Am I to 
give him up 1 or can any thing else be done for him, as Mr. Smith 
is rather anxious about the matter 1 Since I wrote to you I have 
been taking a look into The Lancet , to see if I could find any in- 
formation there. In the 6th volume of that work, I see related, 
at page 408, by Dr. Lefevre, a case of diabetes cured by blood- 
letting ; but whether in this case such a plan of treatment would 
be successful, I am at a loss to determine, nor am I, in present 
circumstances, inclined to try the experiment. If you could spare 
time to write me a line, I shall feel very much obliged. 
I remain, your’s truly.

The influence which the science of chemistry exercises upon 
veterinary science is much greater than is generally imagined; 
and I believe that, ere long, a knowledge of the principal truths of 
chemistry will be expected in every well-educated man, much more 
the veterinary surgeon, to whom it is certainly as indispensable as 
to the physician, or any other branch of the healing art. 
In the present and some future papers, I purpose reviewing, in a 
familiar way, some of the principal theories of Professor Liebig on 
the connexion between chemistry and physiology. This is a field 
of inquiry that will pay well for cultivation, as it will give the 
student not only new and more perfect ideas of the vital processes
