LAMENESS, FROM VARIOUS CAUSES. SAE 
son of the year permits, apply cold water to the hoofs, often and 
freely. At night the feet are to be wiped perfectly dry, and, by 
means of a sponge, a portion of the following mixture must be 
rubbed on: Kerosene oil and honey, equal parts; or neats-foot 
oil and turpentine, equal parts. Notwithstanding the very best 
treatment, the restoration of the foot to comparative or natural 
soundness will be a work of time, an” sometimes, in bad cases, or 
one of long standing, an impossibility ; yet the above treatment is 
the best we are acquainted with. Some persons prefer to use 
moistened clay, cow-dyng, ete., but they are of no value, only in 
consequence of the rroisture they contain, and clean water is far 
preferable. 
The Mechanism of the Hoof.—A brief exposition of the mechan- 
ism of the hoof may possibly interest the reader. The external 
covering of the foot may be divided into four parts; namely, the 
wall, bars, sole, and frog. The external portion, or wall, serves to 
defend the sensitive tissues within. The wall, or hoof, is composed 
of small filaments, or hollow tubes, consolidated in such a manner 
az to preserve their canals distinct. These canals constitute the ex- 
crementitious outlets of the hoof, from which morbid materials find 
an outlet, and in these canals are found the vessels by which horn 
is secreted or produced. The small vessels arising from the vas- 
cular and nervous tissues of the foot proper enter, also, into these 
canals. The bars are a continuation of the external portion just 
described. They form an angle at the heels, which terminates to- 
ward the toe. They thus serve to give strength and durability to 
the hoof, and also to prevent contraction at the heels. When 
these bars are cut away or demolished hy means of the butteris, 
then the foot often goes to “rack and ruin.” The sole is much 
more elastic than the crust, and is a medium of the sensitive fac- 
alty, through which, together with its powers of electricity, the 
percussion of the foot against the ground is regulated. The frog 
is much more elastic than either of the parts just described. Any 
unnecessary paring of the same is a monstrous evil. 
On the internal portion of the above-named parts we find a 
beautiful set of leaves (lamin), resembling those found in the 
ander surface of a mushroom, Their number is said to be five 
hundred. These articulate with a like number given off from the 
sensitive tissnes of the foot proper, each laminw hav.ng two sides 
and an edge, from a series of articulations, numberiag three thou-
