DESCRIPTION OF A SINGULAR LUSUS NATURE. 407 
termination of each spine,—also a double number of ribs. The 
ribs were given off from 'the superior and inferior spine, and met 
at the middle of the sides, forming only one cavity. There was a 
trachea and oesophagus from each head, which united near to their 
termination in the lungs and stomach. The hind leg, which arti¬ 
culated with the superior parts of the ossa innominata, was double 
from the hock, and at its termination were three distinct feet, per¬ 
fectly developed. The organs within the thorax and abdomen 
were single, excepting that at the termination of the colon the 
intestine was bifidated, forming two rectums, which terminated un¬ 
der each tail. 
When the animal was placed in a standing position, the two 
fore legs, which grew from the inferior spine, pointed upwards 
over the shoulders of the outer fore legs. In all, as I have stated, 
there were four fore legs, and three hind ones, and nine feet. The 
umbilical cord entered the abdomen on the side at the union of the 
ribs. It is perfectly at your service.

CiESAREAN Operation. 
Since writing the above, I have performed the Caesarian opera¬ 
tion on a cow. The circumstance which rendered the operation 
necessary was a severe injury which the animal had received two 
days previously; and, since that time, her shewing symptoms of 
approaching parturition. Several attempts had been made to 
extract the calf, but with no avail. 
The singular effect of the injury was a twisted uterus, which 
had been previously ascertained. It was completely rotated, even to 
the termination of the vagina, which rendered all attempts to pass 
the hand impracticable. 
As all attempts to alter the situation of the uterus had been made 
by Mr. Relph, a very skilful practitioner, before my assistance was 
required, I proceeded at once to the operation. Having got every 
thing necessary for the operation, we secured the animal in the 
same way as related in my successful case on the sow. I com¬ 
menced the incision a little anterior and inferior to the spinous pro¬ 
cess of the ilium, cutting downwards and forward, to the extent of 
eight or nine inches, dividing the skin, muscles, peritoneum, and 
uterus, in their respective rotation; which was accomplished in 
a few minutes, and without the loss of one ounce of' blood. Mr. 
Relph now introduced his liand, aiul with little diflicultv removed
