OBSERVATIONS ON URINE AND URINARY 
DEPOSITS IN RELATION TO DISEASE. 
By Professor Varnell, Royal Veterinary College, London. 
Malassimiiation of the materials taken into the intestinal 
canal is likely to occur in the horse as in other animals, 
varying, however, both in its degree and nature. This being 
the case, we may reasonably conclude that the products of 
secretion, particularly those of the kidneys, would also var}^ 
both in relation to the proximate principles of which the 
aliment consists as well as of those of which the animal body 
is composed. These variations being determined, and com¬ 
pared with the healthy standard, ought to give us a clue to 
the nature of the derangement in an animal's body, as also 
of the organs principally involved. It need not surprise us 
when we consider the probability, nay, the almost certainty, 
of unnatural substances, in a fluid state, being absorbed from 
the interior of the intestinal canal and conveyed into the 
circulation, that they should cause a disordered state of the 
whole system, but especially of those organs whose duty it is 
to eliminate such materials from the blood. Bearing this in 
view, the physical character of the secretions which we often 
observe—the urine, in particular—ought to suggest to us the 
advisability of determining the nature of the changes that have 
taken place. Knowledge thus obtained, but which can onty be 
arrived at by aid of the microscope and chemistry, would, no 
doubt, materially assist us in forming a true diagnosis, and also 
in suggesting suitable therapeutics for the expulsion of that
