within the chest. I related to him the new plan of treatment 
which I intended to pursue, but he seemed rather dubious as to a 
favourable prognosis. He suggested tapping ; but I was deter- 
mined to put iodine to the test of experiment in this case. I, 
accordingly, prescribed a ball, to be given twice a day, composed 
of iodine and linseed meal ; and, before the sixth day, there was a 
manifest improvement in the case. The animal began to get more 
lively, and to take some food, with an abatement of the gurgling 
sound of the water in the chest. I now ordered the medicine to 
be given once a day, and, before the termination of the second 
week, a perfect recovery was effected. 
The other case presented a still more obvious testimony of the 
therapeutical action of the medicine. The patient had been seized 
in the same manner, and to the same extent, as in the former case, 
and as decided a benefit was the result in a very few days. Not 
long afterwards the animal was perfectly restored to his usual 
hilarity of spirits, and good working condition. 
From such cases I have come to the conclusion that its action in 
hydrothorax will be decidedly beneficial ; but at present I leave it 
for others to experiment on the subject. 
ON FLOODING AND INVERSION OF THE UTERUS. 
By T. Herbert Barker, Esq. M.R.C.S . Bedford. 
Sir, — I t is well known that the cultivation of a knowledge of 
comparative anatomy and physiology has thrown great light upon 
the functions of the human system, and instances are not wanting 
of a similar service rendered to human pathology by the careful 
examination of some analogous diseases as occurring in the lower 
orders of animals. With the view of eliciting information on a 
point of obstetric pathology, connected with the lower animals, I 
am induced to lay the few following observations before yourself 
and your readers. 
If you or any of your numerous readers will favour me, through 
the medium of your journal, with any facts bearing upon the sub- 
ject of the following remarks, I shall be greatly obliged ; and it 
would be needless to offer any other inducements for such commu- 
nications, after stating that your or their experience may tend to 
set at rest some difference of opinion on a point of human obste- 
tricity, as expressed in many valuable works on that branch of
