A Hoof Pad to Prevent Nail Pricks .—It is well known that 
nail pricks are uncomfortably common in any large stable of 
city work horses, and an appliance that will prevent their oc¬ 
currence should be accepted with open arms. A leather cover¬ 
ing to be effectual must be made of heavy leather that will bear 
too heavily upon the sole of flat-footed horses, and besides will 
favor loosening of the shoe and are expensive. Sheet-iron 
plates are difficult to apply and are objectionable for reasons too 
well known to mention. The pad for this purpose must be 
cheap, it must be easily made and applied at the time of shoe¬ 
ing and must possess no objectionable feature, such as loosening 
of the shoe, formation of corns, lameness from sole pressure, 
thrush, etc. These requirements seem to have been met by the 
invention of Mr. Thos. Donolan, of Armour & Co.’s, Chicago, 
in whose stable of three hundred horses not a single nail wound 
was sustained during six months, while before their use from 
five to fifteen horses were continually out of service from the 
lameness of nail wounds. The pad consists of three layers of 
canvas strengthened across the heel by a band of sheet iron two 
inches wide. With a simple cutting machine the horseshoer 
can make one of the pads in a few moments and adjust them 
without delay.— (L. A. M.)

Cheorae Hydrate Anesthesia in the Horse [Pro/. 
Frohner , Berlin ].—As general anaesthetics for the horse, the 
veterinarian has at command, principally, chloroform, morphine, 
and chloral hydrate. In regard to chloroform, Frohner in a 
previous publication pointed to the facts, that chloroform for 
horses is not a very safe anaesthetic. Similar bad experiences* 
were had by Venerholm, Ranzilotti and others. Although the 
administration of morphine has many advantages, it has also 
some disadvantages ; before all, that as after affects in many 
horses it causes uneasiness and excitement, which often lasts 
for several hours after the operation. Furthermore many ani¬ 
mals suffer for hours from choking and symptoms of vomiting 
as a result of the morphine injection, which eventually may 
have very serious effects (foreign-body pneumonia). Frohner,
