THE BEST MODE OE TREATING CANKER? 
To the Editors of 6 The Veterinarian? 
Gentlemen, — Will any of your numerous contributors 
who may treat 66 canker’* in the foot of the horse successfully, 
kindly inform the readers of the Veterinarian , what are the 
remedies so employed ? 
I have more cases of the kind than fall to the share of 
most — I would it were otherwise — and, I confess that, do 
what I will, my labour very often ends in disappointment. 
It must be borne in mind, that the disease exists amongst a 
number of coal-pit horses, which continually work on wet 
roads, and that unless they become the subjects of a long and 
troublesome affection, they are never removed from this abode 
of wet and darkness. 
I have used, in various forms, sulphuric acid, nitric acid,

bichloride of mercury, quicklime, bichromate of potass, arid 
the actual cautery. 
Yours faithfully, 
An old Pupil.

ON SOME NEW PROPERTIES OF FRESHLY CALCINED 
WOOD CHARCOAL. 
By M. Moride. 
The deoxidizing power of wood charcoal is well knowm, 
when used in the dry state and under the influence of an 
elevated temperature ; but I do not know that any one has 
mentioned it as reducing metals in the midst of neutral, 
alkaline, or acid liquors, neither am I aware that any one 
has observed that in contact with a dilute and alcoholized 
acid, freshly calcined wood charcoal caused the formation of 
ether. 1 am continuing this study, but I have determined to 
make known the results of my first experiments. 
Coke, charcoal from lignites, animal and bone charcoal, do 
not produce the effects of which I am about to speak.
