I have seen them literally starved, and full of grumous blood. It 
is remarkable that I never met with this worm until I resided in 
Somersetshire, and that since that time I have often seen them 
in kennels and other places, especially in the miserable animals 
employed in carrying coals from the pits to the neighbouring 
towns and villages.” 
From this quotation it will be observed that he does not men- 
tion the length of them ; but from his calling them “ leech 
worms,” one is inclined to believe that they were but short, 
though he may use this term on account of their supposed suc- 
tion of the blood. 
Some few (not one in fifty) of those in my case were of a dark- 
ish colour, as if they had contained a little blood ; but I did not 
open them.

A Case of Vomiting in a Cow. 
By Mr. Joseph Carlisle, V,S., Wigton. 
My dear Sir, — Permit me to ask your opinion respecting a 
case of vomiting in a cow which has existed for about ten days, 
and set at defiance all my endeavours to overcome. I do not 
perfectly understand the cause of it, but I suspect it to be some 
foreign substance in the rumen or first stomach. 
The cow was in perfect health and prime condition when the 
vomiting was first observed. She has about three months to go 
in calf, and is beginning to look very thin. 
Bleeding and purging have not done any good ; in fact, the 
owner is not agreeable that any more medicine should be ad- 
ministered, as she is generally much worse after it. 
She is at all times anxious for food, and will eat a good quan- 
tity of bran mash and turnips ; but the moment she has finished 
her meal, and particularly if she should get a little hay, she will 
begin to shew symptoms of uneasiness, and commence vomiting; 
previous to which she will curve her back, straddle with her hind 
legs, and frequently urinate. The rumen becomes distended with 
gas, and a regurgitating motion is observed in the course of the 
oesophagus. She continues to vomit at short intervals until the 
whole is ejected. She will sometimes retain her mashes for a day, 
and appear quite well, but the moment she receives a mouthful of 
hay the vomiting returns.
