is process and the accepted view of
vaccinia is very close. The variolous virus is believed to pass
through the cow, and there to become attenuated, so that inoculations
from the cow-pox no longer produce variola in the human subject, but
cow-pox (vaccinia). As an allied process, though of very different
result, mention may be made of some collateral experiments of Pasteur,
also performed recently. Briefly, it has been discovered that the
bacillus of the "rouget" of pigs undergoes an increase of virulence by
being cultivated through a series of pigeons. Inoculations from the
last of the series of pigeons give rise to a most intense form of the
disease. It will be remembered that the discovery of the bacillus of
"rouget" of pigs was due to the late Dr. Thuillier.--_Lancet._

Very few persons realize the necessity of cultivating an equable
temper and of avoiding passion. Many persons have met with sudden
death, the result of a weak heart and passionate nature.

CONVENIENT VAULTS.

This is a subject which will bear line upon line and precept upon
precept. Many persons have availed themselves of the cheap and easy
means which we have formerly recommended in the shape of the daily use
of absorbents, but a larger number strangely neglect these means, and
foul air and impure drainage are followed by disease and death. Sifted
coal ashes and road dust are the remedy, kept in barrels till needed
for use. A neat cask, filled with these absorbents, with a
long-handled dipper, is placed in the closet, and a conspicuous
placard directs every occupant to throw down a dipper full before
leaving. The vaults, made to open on the outside, are then as easily
cleaned twice a year as sand is shoveled from a pit. No drainage by
secret, underground seams in the soil can then poison the water of
wells; and no effluvia can arise to taint the air and create fevers.
On this account, this arrangement is safer and better than
water-closets. It is far cheaper and simpler, and need never get out
of order. There being no odor whatever, if properly attended to, it
may be contiguous to the dwelling. An illustration of the way in which
the latter is accomplished is shown by Fig. 1, which represents a neat
addition to a kitchen wing, with hip-roof, the entrance being either
from the kichen through an entry, or from the outside as shown by the
steps. Fig. 2 i
