packed very closely together, and, some days before the animal was 
taken ill, the hay began to sweat, and a grey coat of mould had 
formed over the surface, and, when the hay was moved, a thick 
bluish vapour attended by an aromatic smell was perceptible. 
The whole of the hay was used as fodder, and even the portions 
covered with mildew were consumed by the horses, and this, to- 
gether with the sweat of the unpurified hay, was, doubtless, the 
cause of the disease.

ON THE POISONING OF SHEEP WITH ARSENIC. 
By Mr. C. Lauder.

Respected Sir, November 23, 1843. 
I SEE plainly that, however well men may mean, still in the 
course of their lives they will do what they frequently regret 
afterwards ; and such is my case just now, so far as relates to the 
trouble to which I put your respected self and your worthy friend 
Dr. Fyffe ; for, after all, the best counsel in Edinburgh informs the

The fourth day after the bath had been applied another bullock

only exhibited inflamed stomach, but I did not see him ; and on 
removing the skin, the cellular tissue, wherever the bath had been 
made use of, was full of extravasated blood, and of the darkest 
shade of red. 
From the lips to the anus the alimentary canal was highly in- 
flamed. The paunch had already parted with many and large 
patches of the secreting coat, and the rest of it peeled off the 
same as if it had been long macerated. The omentum was disco- 
loured and the texture destroyed, as also the texture of the kidneys. 
The peritoneum inflamed, and containing a large quantity of serum. 
The liver gangrenous. The larynx, trachea, bronchi, and paren-
