infants fed from the bottle;
free ventilation of living rooms, and especially of bedrooms; and by
protection, as far as possible, being afforded from a hot sun, as well as
by avoiding excessive exercise. All animal and vegetable matter should be
removed from the vicinity of dwelling-houses as quickly as possible
(indeed, these should be burnt instead of being put in the dust-bin), the
drains should be frequently disinfected and well flushed out, especially
when the mean daily temperature of the air is above 60 deg. F.

Time will not admit of more than a mere mention of the relations between
meteorological phenomena and the mortality from many other diseases and
affections, such as apoplexy from heat, sunstroke, liver diseases, yellow
fever, cholera, whooping-cough, measles, etc., especially as the state of
our knowledge on the subject is so very limited. A comparison between the
mortality from several diseases in this and other countries shows that
certain of these do not prevail under closely corresponding conditions.
Thus the curves of mortality from whooping-cough, typhoid fever, and
scarlet fever do not correspond with the curves of temperature in both
London and New York, and the same may be said of diarrhoea in India. It is
therefore evident that some other cause or causes than a varying
temperature must be concerned in the production of an increased death-rate
from these diseases. The subject is of great importance, and I do not
despair of our obtaining some day a knowledge of the agents through which
meteorological phenomena act in the production of increased and decreased
death rates from certain diseases, and the means by which, to a certain
extent, these injurious effects on man may be presented.

P. Rosenbach has found experimentally that potassium bromide diminishes
the sensibility of the cortical substance of the cerebrum to electric
excitement, while, the excitability of the underlying white substance
remains unaltered.

CONSUMPTION SPREAD BY CHICKENS.

In a village, C., near Weimar, where for many years no case of tubercular
phthisis had taken place, two years ago several families suddenly
discovered one of their members to be suffering from the disease. After a
long inquiry, it was discovered by accident that all these families had
been buying their spring chickens from one and the same place, viz., from
a
