IMPERFORATE ANUS IN A CALF. 
By Mr. B. Bull, Worthing. 
This animal lived five days after the birth. No medical treat- 
ment was attempted. The usual situation of the anal orifice was 
perfectly level, and presented not the slightest trace of any open- 
ing. 
I had an opportunity of examining it after death, and found that 
the rectum was turned back five or six inches from the usual place 
of the anus, and inserted like a muscle upon the os pubis, with an 
almost perfect obliteration of the canal four or five inches in length. 
HERNIA. 
In a letter from Mr. STORRY, of Pickering, principally on other 
matters, I find the following description of his manner of operating 
in cases of umbilical hernia in colts : — 
After having cast the patient, and secured him on his back, he 
takes hold of the extremity of the hernial sac, and by gentle mani- 
pulation and pressure, he returns the intestine into the abdomen. 
He then makes an incision over the orifice, through which the gut 
protruded, and carefully separates the skin from the sac. He again 
grasps the sac, now denuded, and gathers it up as tightly as he 
can close to the hernial aperture, and ties round it a white leathern 
lace or string, introducing a few stitches through the part which he 
is tying until it is completely secured, when he cuts off the now 
superfluous part of the sac. 
He finally brings the integument together, closes it by suture, 
and puts a strong adhesive plaister over the whole. 
EXPERIMENTS ON DIGESTION. 
By Professors TlEDEMANN and GMELIN, of the University of 
Heidelberg. 
The reputation of Professor Tiedemann is sufficiently esta- 
blished on the continent. The translation of the first volume of 
his Comparative physiology by Drs. Gully and Lane has intro- 
duced it to the English reader, and it now finds a place on the 
shelves of every medical and scientific person. From the library 
of the veterinary surgeon it should not be absent.
