410 BALLOON INTELLIGENCE IMPROVED. .
Dobson, a physician at Liverpool, has confirmed and re-
newed all these experiments upon various subjects. Mr,
Park, a surgeon, remained ten minutes in a stove heated
to 85 degrees. Sir Charles Blagden remained eight mi-
nutes in a room heated to 262 of Farenheit, or 102 of
Reamur. During the first seven minutes his respiration
was perfectly easy; but in the course of another minute
he felt a degree of obstruction and some pain, which gave
him notice that it was time to drop his experiments. His
pulse beat at 144 the minute, or double the time of its
natural stage.
The writer from whom these facts are cited, remarks,
that the Author of Nature has endowed man with the fa-
culty of sustaining, at least to a very near degree, the
same temperature of body in spite of all the changes of
climates and seasons; and with respect to the enjoyment
of health, to traverse the whole globe with impunity.—•
Nature has also most happily adapted the constitution of
various animals to their different situations—The lizard
and the cameleon remain cold under the equator, while
the whale and the sea-calf, under the frozen zone, retain
a temperature considerably warmer than human blood.

That gentleman, accompanied by M. Lhoert, made a
second aerial excursion, which has confirmed many of
their former experiments, and produced some dew and
interesting; results,
M. Robertson has ascertained that sounds may be con-
veyed upwards to the height of 1200 feet, while down
wards they can be conveyed only one half that distance.
