ON TIIE HEALTH OF HORSES.

He neighed three or four times — he made various efforts — his eyes 
rolled in their orbits. By one strong respiratory effort he looked 
around him — his limbs became contracted — one respiratory sound 
was heard — and he died. All that remained was some bloody dis- 
charge from the nostrils. 
The autopsy was eight hours after death. I remarked a great 
quantity of black blood in the chest: the lungs were voluminous, 
filled with blood, and unusually large in quantity. Towards the 
posterior and diaphragmatic portion of the right lobe or pleura 
a clot of very thick blood was observed. The pleurse were of a 
deep hue — the ventricles soft and discoloured — the right ventricle 
contained black blood without any yellow clot. The interior of 
the ventricles and some large arterial trunks have a violet tint 
and smell. The bronchi, the trachea, and the larynx, not only 
contain a red and spumy blood, but they have also a deep red. 
The abdomen does not offer any thing remarkable. 
In the last month many other horses have been affected with 
pulmonary complaints. 
INCONTINENTIA URIN^E. 
By Herr Schrebe, V.S. to the Royal Prussian third Artillery 
Brigade. 
Incapability of retaining the urine is, on the whole, a disease 
rarely met with among our domesticated animals. I have seen but 
very few cases in the course of my practice in which from injury 
of the contractor muscles of the urinary bladder the animal has been 
unable to open or close it at will, and these few have all been in 
male animals. I have never met with one in a female, although 
the form of the bladder and the structure of the muscles which act 
on it are similar in both sexes. It is the urethra only which is 
differently shaped in male animals to what it is in females. Al- 
though this disease is not attended with absolutely fatal conse- 
quences, it deteriorates materially from the value of the animal, 
and, if it has existed for some considerable period, is very obstinate, 
and cannot be cured without difficulty. 
In cases of this disease, the constantly flowing urine, on running 
out of the urethra, collects at first in the reservoir (bulbl), whence it 
dribbles out, or, when the animal moves, runs out in greater quan- 
tities at once. The injurious consequences attendant on the urine 
being thus collected in a part never destined for such a purpose soon
