On Calculous Concretions in the Horse, Ox, Sheep and Dog. By 
Professor W. J. T. MORTON, Lecturer on Medical Chemistry 
and Veterinary Materia Medica at the London Veterinary 
College. 
We have great pleasure in directing the attention of our readers 
to this new proof of the zeal and talent of our friend, Professor 
Morton. The subject of calculous concretions is an important one, 
as involving the interests of our patients, our employers, and our- 
selves. The field is a perfectly novel one, and admirably treated. 
We shall again and again have recourse to it. 
We particularly direct the attention of our readers to the follow- 
ing history of calculi in sheep, by Mr. W. C. Crabbe : — 
Four years ago, says he, when living at Plumstead, in Nor- 
folk, several instances of vesical calculi in sheep fell under my 
notice. 
They occurred in a flock of about twenty-three score sheep, 
and of these animals I had the charge. In the winter of 1839, 
the flock was divided into what in Norfolk are called heads 
and tails, or such as were fit to fatten, and such as yet needed time 
and keep to bring them into fattening condition. The poorer sort, 
constituting about eleven score, were sent to grass, and to these 
nothing deserving of notice happened. Such as were kept at 
home to fatten were fed in folds on mangel-wurzel and hay, oil 
cake, brank meal, or buck-wheat and white peas, being allowed 
no water. On this food they became nearly fit for the butcher by 
the spring, when a few of them were observed to be ailing. 
The symptoms exhibited were restlessness — frequently getting 
up and lying down again — repeated and strained efforts to urinate, 
when but a small quantity of fluid was voided — impaired appe- 
tite — disinclination to defend themselves, rather putting up with 
an injury than attempting to repel it ; and a solitary disposition 
evinced by their lying apart from the remainder of the flock. I 
could perceive no decided symptoms of any known disease, neither 
could the shepherd recognize any usual complaint. 
He bled them from the facial vein ; but on a more careful ex- 
amination we remarked that the abdomen was considerably en- 
larged. All the symptoms above related were observed to be
