PROTRACTED UTERO-GESTATION IN COWS. 
The reservoir D also receives the cap or lid, likewise of copper, E, which 
has a rim that fits tightly to the top of the reservoir. This cap has a tube 
brazed upon it which is sufficiently large to admit of the pipe of an ordinary 
pair of bellows. In the interior of the lid there is inserted another perforated 
copper plate, convex to the reservoir D. 
The tobacco is put into the reservoir D, and some lighted cotton or wad- 
ding dropped upon it, for a few moments, and then the cap placed upon it, and 
the bellows put in operation ; and if any escape of smoke arises it is easily 
obviated by a portion of wet tow bound tightly round that part. I can state 
it to be a very effectual apparatus for the purpose, and, from all the parts 
being so readily got at, it is rendered portable, and is easily kept clean : a pair 
of bellows can always be obtained. 
CASES OF PROTRACTED UTERO-GESTATION IN 
COWS. 
By John Tombs, M.R.C.V.S., Stratford-on-Avon. 
I perceive in The Veterinarian for this month a case of pro- 
tracted utero-gestation by Mr. Cox, which induces me to relate 
two similar cases, besides making a few observations on the like 
subject. 
Case I. — A butcher of this town killed a fat cow in the latter 
part of November, which he purchased of a neighbouring farmer. 
He removed from her inside what he supposed to be an indurated 
tumour. At his request I examined it the day after, and found it 
was a full-grown foetus, coiled up quite round. The placental cover- 
ing was very thin, and like white leather : it was lined with hair. 
The head was lying back on the right haunch, that part in contact 
with it was flattened ; the fore feet were under the pelvis, and the 
hind feet close to the sternum. The spine was curved. Putre- 
faction appeared to have taken place recently. The teeth were as 
large as a four or five months old calf’s; the bones of the head 
were as solid as a calf’s of the same age. She was bought as a 
barren cow last Michaelmas twelvemonth, and never had access 
to the male until a few weeks before she was slaughtered. Of 
course, she was pregnant at the time she was bought : that would 
make the foetus fourteen months old, which accounts for the great 
size of the teeth and solidity of the bones of the head. Undoubt- 
edly, the long retention of the foetus in utero was attributable to its 
unnatural position : the singularity in this case is, that she never 
shewed any signs of parturition. 
CASE II. — About two years since I attended a heifer that had 
labour pains. The vaginal opening being closed, no attempt was
