es of the
case. May it not be well, through the medium of wet sponge over the
thorax, to apply a continuous but gentle current of galvanism, so as to
stimulate the heart's action, keep alive the respiratory movements, and
thereby assist in the maintenance of the functions of the body?

TEMPERATURE, MOISTURE, AND PRESSURE IN THEIR RELATIONS TO HEALTH.

At the recent meteorological conference held at the Health Exhibition, Dr.
J.W. Tripe read a paper of much interest on some relations of
meteorological phenomena to health.

In ages long past these relations excited much attention, but the
knowledge concerning them was of the vaguest kind; and indeed, even now,
no very great advance has been made, because it is only quite recently
that we have been able to compare a fairly accurate record of deaths with
observations taken at a number of reliable meteorological stations. The
more useful and searching comparison between cases of sickness, instead of
deaths, and meteorological phenomena has yet to be accomplished on a large
scale in this country, and especially as regards zymotic diseases. In
Belgium there is a Society of Medical Practitioners, embracing nearly the
whole country, that publishes a monthly record of cases of sickness, of
deaths, and of meteorological observations; but the only attempt on a
large scale in this country, which was started by the Society of Medical
Officers of Health for the whole of London, failed partly from want of
funds, and partly from irregularity in the returns. My remarks, which must
necessarily be very brief, will refer to the relations between (1)
meteorological phenomena and the bodily functions of man, and (2) between
varying meteorological conditions and death-rates from certain diseases.

As regards the first, I will commence with a few brief remarks on the
effects of varying barometric pressures. A great deal too much attention
is paid to the barometer if we regard it as indicating only, as it really
does, variations in the weight of the column of air pressing upon our
bodies, because, except at considerable elevations, where the barometer is
always much lower than at sea level, these variations produce but little
effect on health. At considerable elevations the diminished pressure
frequently causes a great feeling of malaise, giddiness, loss of strength,
palpitation, and even nausea; and at greater heights, as was noticed by
Mr.
