REMARKS ON THE FOREGOING CASES. 
By W. Jackson, Esq., M.R.C.S. 
Sir, — Mr. Mogford having favoured me with a perusal of his 
two cases of paracentesis thoracis prior to publication, I am de- 
sirous of giving my testimony to the correctness of his statement 
as regards the second case, in which Mr. Mogford was so oblig- 
ing as to request my opinion as to the certainty of eff usion in the 
thoracic cavities. Of the first case I had no knowledge but by re- 
port. 
I have reason to thank Mr. Mogford for the opportunity of 
seeing Mr. Taplin’s horse, and of witnessing the manifest good 
derived from his judicious treatment. I coincide with Mr. Mog- 
ford in opinion, that tapping, to produce a curative effect, should 
be performed as early as fluid can be satisfactorily detected ; and 
I am also disposed to think, with him, that if the second ‘case 
had been continued under his care, a more fortunate termination 
might have ensued. Mr. Mogford has omitted one circumstance, 
which to me appears worthy of notice. I allude to the rapid and 
complete coagulation of the fluid withdrawn in case 2, an occur- 
rence which, I believe, does not take place with any dropsical 
fluid removed from the human subject. 
ON MURRAIN IN COWS AND CALVES. 
By Mr. Joseph Carlisle, F.S., Wigton. 
The following is a curious and unequivocal fact, that calves 
newly dropped have had confirmed murrain at the time, clearly 
proving that they must have imbibed the disease from the parent 
during utero-gestation. I have witnessed, at the time of birth, 
every symptom and effect of the disease truly manifested. Cattle 
will not take the epidemic a second time, even from vaccination, 
or at least according to my experience. 
Cattle, in this part of the country, have done very badly after 
calving. There is a great tendency to force down the uterus, 
and it is generally from four to eight days before the placenta 
comes away. In several cases I was obliged to remove it by 
manual force. In six cases that came under my treatment, the 
uterus was completely forced down at the time of calving. When
