SCIENTIFIC MISCELLANY.

lHE lHEOK1 OF VACCANAAAoN'-
Prof. Iyndall suggests that, just as the
soil may be so efceetually robbed Of
some essential ingredient by one abund-
ant crop as to be incapable of produce
ing another, so in the human system a
parasitic disease may so completely ex-
haust the blood of some ingredient ne
ccssary to the growth and propaga-
ton of the parasite that the production
of second crop in fatal or consider
able quantity may be impossible. It
would thus appear that protective vac
cination or incubation is simply the
introduction into the blood of weaken.
ed and comparatively harmless disease
germs to consume the material which
might become food for similar germs in
a more vigorous and dangerous condi-
ton.

Shaler Schmith, overturned locomo-

pounds per square foot. At St. Charles
Jail was destroyed in 1877, the press
ure required being 81 pounds per
square foot AT Marshfeld, in 1880.

necessary being SO pounds per square

ures, Mr.. Smith has instanced numer-
Gus cases of trains blown off rails, and
bridges, ETC., blown down, by gales Of
