The summer Solstice and Thermomet-
Sanitary Rustication.
The arrival Of the solstice on the Dist of
June, although it often escapes notice, is an
event Of the season not less important than
the stormy equinox. A few days ago it
seemed as if the hottest blasts Of summer had
been let loose, and even in the Middle States,
in some localities, the thermometer regis
tered over 101 degrees in the
shade. Since then the cool spell
came over the same localities and
the mercury ranged in the sixties and seven
ties. The northward march of the sun, we
should have expected, would bring steadier
thermal increase; but instead, we see, within
short periods the presence of that luminary
climaticaiy echpsed. It is mysterious fact,
hardly Ineligible, that SO early in June the
thermometer should mount up in Virginia and
Maryland even higher than it does in Florida
and Cuba. The only explanation we can give
of the phenomenon is that the hottest air
stratum is not that which touches the
earth, but is suspended, and may,
even in high ATTITUDES, be DETECTED
downwards Mr.. Glaisher the scientific
aaronaut, found that at times an ascent
of over ten thousand feet above the sea level
did not cause a fall, but rise, in his Their
mometers, showing that the radiation of ter
restrial heat accumulates in the higher aerial
strata This discovery overthrows the uni
versatility of the rule which SO many scientists
have always followed, and by which they con-
fdently reckon the temperature will diminish
one degree for every three hundred feet Of
perpendicular ascent Strange, too, as it may
appear, physical geographers have shown that
though Canada and Louisiana have respec-
lively in July the mean temperatures sixty-nine
degrees and eighty-one degrees Fahrenheit,
yet on the 21st Of June Canada receives more
heat from the sun than Louisiana, and, what
is more surprising still, the Arctic regions then
receive as much as the equatorial.
The climatic effects Of the solstitial con-
ditions do not, it is true, attain their maxi
mum until some time has elapsed. At New
York the greatest cold does not occur till
month after the winter solstice, nor is the
a month after the 2lst of June But for some
time past las will be the case for some weeks
to come) the earth has been receiving, in the
long days, more heat by day than it can radi-
ate in the short nights. The only influential
agency bringing cool weather to us now is that
which tempers our heat by the aerial waves of
low temperature coming from the cold-tipped
SUBMITS Of the Rocky Mountains or from the
boreal regions Of British America. These
essential facts of the summer cli1natology Of
the United States should warn our sanitary
| authorities to prepare for the maximum vo-
lence of the heated term, which will come in
twenty days. For those who are contem-
plating trip for health it is more important
therefore, to rustcate for the next three or four
weeks than at any other period of the sum-
mer. Once tide over the dangerous early and
mid-July heats, so deadly to our young and
!. FAINT population, and the worst is past,
