A CASE OP AN ANIDIAN MONSTER EXISTING 
WITH TWIN CALVES. 
By W. Snowdon, Slingsby. 
Having read an account of “Anidian Monsters” in the 
June number of the Veterinarian for last year, and one 
having been sent you by my old master, Mr. Bowman, of 
Howden, I am induced to forward you a similar specimen, 
which I have just met with. 
The particulars are as follows : On the 30th of January, 
about eight o’clock a.m., a cow, the property of Mr. Hicks, 
of Slingsby, produced a healthy female calf. Nothing unusual 
was observed during the day, but about six p.m. the owner 
called upon me and wished me to look at the cow as she was 
in pain, and he thought that something like another calf was 
making its appearance. I went immediately, and found a 
membranous sac hanging from the vagina to nearly as low 
down as the animal’s hocks. I immediately punctured it, 
with a view to give exit to the fluid it contained ; a small 
quantity only escaped. This brought to light the turns naturae 
attached to the placental membranes by an umbilical cord. I 
divided the cord, and after having removed the membrane, I 
observed that the cow was still in pain ; I therefore made an 
examination per vaginam and found that another calf was in 
the uterus. I gently pushed this foetus forward, and succeeded 
without much difficulty in bringing it away, although its 
breech was presented and its hind legs were placed under 
its belly. It was a male calf, larger than the first, and finely 
proportioned, but dead. The cow required little or no treat- 
ment, and continued afterwards to go on well. 
[As our last year’s volume contained a full description of 
these “Anidian Monsters,” by Mr. Gamgee, it is almost super- 
fluous to give a minute account of this specimen, differing so 
little as it did from others of the same class. Its shape is that 
of a flattened ovoid, having a thickness, which is pretty uniform 
throughout, of about two inches, and measuring in its long
