ON TI1K FORMATION OF FAT AND MUSCLE.

tural arrangement, linked with those grand principles that mo- 
dify the external conformation of every animal, locality, clime, 
and soil ; and, lastly, the manner in which beans and acorns 
harden the flesh of animals. That they do so is an undisputed 
fact. The hardness of flesh or muscle depends on the richness 
of its lymph or fibrine. Beans and acorns contain large quan- 
tities of vegetable albumen compared with any other food given to 
horses or cattle. It is on this account that food which contains 
a large share of albuminous constituents, when given to horses, 
cattle, or pigs, makes them develop so great a degree of mus- 
cular firmness; but when substances rich in starch, mucilage, 
gum, or the saccharine principle, are added to beans or acorns, 
the hardness of the flesh becomes lessened, and the fat more 
emollient. I have practically proved this with horses. I have 
given beans and acorns to horses with hay chaff’ on the farm. 
The muscular power has been augmented ; the flesh feels hard, 
they work well without fatigue ; do not perspire, and, in fact, they 
are in full vigour. I have altered their diet, and given, instead of 
chaff, turnips, either the swede or common globe, and the effect is 
soon visible. The flesh becomes soft and puffy — little work excites 
perspiration-—in fact, the animal is soon reduced from a state of 
good firm condition to one bordering on debility. From the 
taking away those substances, beans or acorns, which possess in 
a maximum degree the richest albumen, and the supplying those 
that contain it in the lowest degree, or minimum, the albuminous 
principle exists in several forms; and by it the living materiality 
of the animal body is by a law of animal chemistry built, under 
the guidance of immateriality. 
COMPOUND FRACTURE OF THE JAW OF A HORSE. 
In looking over the Sporting Magazine of February, in the 
last year, we found the following case. It does great credit to 
Mr. Mavor. Why does not he, and others of his brethren, more 
frequently give publicity to a few of these cases, which do them- 
selves and their profession so much credit? 
On the 13th of October last, a favourite horse got loose in his 
stable, by pushing his head between the jamb and the door of the 
harness-room adjoining. The animal becoming alarmed, tried to 
draw back ; but his head was completely fixed, and the more he 
struggled the tighter it became. The consequence was a fright- 
ful compound fracture of the lower jaw, which hung pendulous, 
while on the near side the fractured bone was forced into the
