Contemplating the |
horrors of hydrophobia one madly |
grasps at any prevention of their occur |
renee, and therefore readily listens to |
any suggestions concerning the best |
means to adopt to protect the comnu- |
nifty from its ravages. A celebrated |
veterinary surgeon says The means
of preserving from rabies consists IN
taking off the edge of the dogs teeth
by the aid of nippers and files. The
surgeon tried the operation upon three
dogs when they were raging mad, and,
Notwithstanding the evident danger to
which he was subjected, succe5 ded.
Six dogs were then let loose to the mad
ours and were bitten furiously, but
without breaking the skin of any of
them. The bitten dogs were watched
for six months, during which time none
of them ran mad, or exhibited the
slightest sign of rabies. The surgeon
was so convinced that the blunted teeth
of the dog could not penetrate through
clothing that he gave his hand, covered
with q glove, to one of the mad dogs.
He moutheO it viciOusly, but when the
hand was relieved the glove was intact,
the bite having only made deep I'M
preston, and, of course, no abrasion.
The conclusion, of course, is that ami
mails in danger of going mad should
have their teeth blunted instead OF
their mouths muzzled. It would prob
ably be the more humane proceeding,
as a muzzled dog in midsummer suffers
miseries of an awful kind.
THE WARMTH OF CLOTHING. In a
careful study of the subject of the
warmth of clothing, recently published,
DIR. Max Won Pettenkofer has pointed
out that the permeability of stuffs to
air is a condition of their warmth. The
London Medical Record gives tho fol-
| lowing abstract OF equal surfaces of
the following materials, he found that
they were permeated by the following
relative quantities of air, the most por-
GUS, flannel such as is used ordinarily
| for clothing, being taken at 100: Elan
mel, 100; linen of medium fneness, So;
| silk, 40 bucksin, So !; tanned leather,
1 channels leather, 81. Hence if the
warmth of cloth depends upon the de-
gree in which it keeps out the air from
our bodies, then glove-kid must be one
| hundred times warmer than flannel,
which every one knows is not the fact.
The whole question, then, is resolved
into that of ventilation. If several lay
ers of the same material be placed to-
| gether, and the air be allowed to per
me8te through them, the ventilation
through the second layer is not much
less than through the first, since the
meshes of the two form a system of con-
tinuous tubes of uniform diameter, and
the rapidity of the movement of the all
through these is effected merely by the
resulting friction. Through our cloth
ing, then, passes a stream of air, the
amount of which, as in ventilation, de-
ponds upon the size of the meshes, upon
the difference of the temperature be-
tween the external and internal atmos-
phere, and upon the velocity of the sur
rounding air. Our clothing, then, is
required not to prevent the admission
of the air, but to regulate the same SO
that our nervous system shall be sensi
BILE of no movement in the air. Fur
Their, our clothes, at the same time, reg
ulate the temperature of the contained
air, as it passes through them, so that
the temperature of the air between the
clothing and the surface of our bodies
averages 81 to sc degrees Fab. The
microscopic property of different ma
terials used for clothing essentially
modifies their functions. This proper
ty varies with the different materials
wool, for instance, takes up more water
than linen, while the latter takes VI
and gives off its watery contents more
rapidly than the former. The more al
is displaced by water from the clothes
the less will be their power of retaining
the heat in other words, they conduc
the heat more readily, and hence we ar
quickly chilled by wet garments.
