wrapped round the bit, well saturated with the rock oil; and ther# 
is every reason for supposing that the wind, power of breathing, 
and the vivacity of the animal, are much improved by it. 
“ The rock oil is a most valuable external remedy in mange, and 
most other skin affections ; it may be also employed internally at 
the same time with great advantage. 
“ The rock oil is likewise a good application to make the hair 
grow, when it falls off, or is removed by accident. 
“ In most cases of grease, cracks in the heels, mallenders and 
sellanders, the rock oil, regularly applied, will prove an effectual 
cure; and for grease it may be used in conjunction with astrin¬ 
gents, or after them, as circumstances may require. 
“ After the inflammation and increased heat* of the parts have 
subsided, in strains, or sprains in the back, sinews, &c. and bruises 
in most parts, the rock oil is of the greatest utility. 
“For thickening of tendons, or their sheaths, windgalls, and 
incipient spavins, in conjunction with proper rest, provided there 
is no particular active inflammation present, the rock oil will be 
found very useful, not only in checking the progressive disposition 
of such affections, but, in most instances, of effecting a removal. 
“ As a remedy for removing an opacity in the cornea of the 
eye, the rock oil will also be found useful. 
“ In most instances of broken knees*, treads, &c. and in recent 
wounds, the rock oil proves the best application ; as well as in 
sloughing w'ounds : it is likewise a good digestive. 
“ We are enabled positively to assert, that hitherto no substance 
has been used or proposed, that embraces any thing like the 
manifold advantages and valuable softening properties, as the 
rock oil; for, when regularly employed, it not only toughens the 
wall of the hoof, but prevents it from becoming brittle; and if 
used as a stopping, the sole and frog are likewise kept admirably 
soft, moist, and elastic ; and by its singular penetrating power, 
w hen applied to the coronet and pastern, in most instances allays 
pain and irritation. 
“ The rock oil is by far the best and most effectual remedy that 
can be possibly used, for the cure of all affections of the skin in 
dogs, particularly mange, and that form of it termed the red 
mange. 
“In its pure state, it is the best application that can be resorted 
to for swelled and sore feet of hounds, and other sporting dogs. 
* “ The following lotion, frequently applied to the part with a sponge, 
will be found serviceable in subduing increased action and heat:—Muriate 
of ammonia, 1 oz.; distilled vinegar, 4 oz.; spirits of wine, 2 oz.; water, 
2 pints : mix.”

Cherry, of Claphum, published by Simpkin and Marshall.”
