ON HiEMATURIA IN CATTLE. 
that*any other person has pointed out the true seat of tliis frequent 
lameness, and I therefore think that I may lay claim to some 
slight originality, as being the first that called the attention of 
the profession to what 1 conceive a matter of some importance. 
I know not whether others have since made similar observations, 
but increased experience has strengthened my opinion, and added 
to the facts that I then brought forward in its support. I have 
since obtained-three specimens of this disease, one accompanied 
with spavin, the others without any enlargement. The history 
of these cases during life I am acquainted with, and they now 
make seven specimens of the kind in my possession. Though 
not perhaps quite so common as the navicular lameness in the 
fore foot, it much resembles it in its nature, and is, I think, the 
cause of nineteen cases out of twenty of every obscure lameness 
of the hind extremity. 
ON HEMATURIA (REDWATER) IN CATTLE. 
By Ml'. J. D. Harrison, r.»S., Lancaster. 
That chonic indigestion in cattle is a principal cause of most 
diseases to which they are incident, has long been observed by 
me; and taking into consideration the complicated structure of 
the digestive organs, we need not be surprised at any derange¬ 
ment, or disease, produced in them, either from accidental or 
other causes. Hsematuria, I am perfectly convinced, owes its origin 
to it, at least in the generality of cases; and I feel quite assured 
that the discolouration of urine is entirely referrible to that cause, 
and not to any nephritic affection, as is too generally and oft- 
times fatally supposed. Scarcity, or a total privation of water, 
evidently appears to be the exciting cause of producing that dis¬ 
ordered state of digestion requisite for the development of this 
disease; and this supposition is still more strongly contirmed, 
by my knowledge of the land situated east and south east of 
this town, a lofty and w’ild region, and where in hot and dry 
summers w^ater can very rarely if at all be procured by the parched 
animals thereon. It is here, in this district, that haematuria rages 
like an epidemic, annually attacking ali ages, and numbers falling 
victims to it; whilst in the surrounding vallies a case very rarely 
occurs, prevented, I have no doubt, by the animals having a 
sufficient quantity of pure water to resort to, when nature may 
prompt them. As a farther corroborative, I am well acquainted 
with one farm upon which, even in a moderately dry summer, 
water is very difficult of attainment; yet the occupier annually 
suffers through this disorder, whilst his immediate neighbours
