INSOLATION—SUNSTROKE—THERMAL FEVER. 125 
rapidity that it had almost all flown out before some could be collected; 
a long tent of oakum was introduced, and the animal, returned to her 
stall, went to eat—thought convalescent. 
This closes the second part of the case; and with this satisfactory 
result is rising also the question-title of the article, and the explanation 
of the first unsuccess. 
About three hours after the operation, desiring to remove the tent 
of oakum which was left first, and to introduce a larger one, I went to 
my patient. I carefully removed the tent, and pulled out with it a 
black long mass, very offensive, measuring 10-^ inches in length—the 
exact length of the space between the two openings of the sides—ltr in 
width, with a seam on one edge, which was nothing else but the piece 
of the handkerchief which had been used first as a seton. How did it 
come there? How did it reach these cavities? are the questions to 
which the whole history of the case has brought us, and which we are 
afraid to answer. 
INSOLATION—SUNSTROKE—THERMAL FEVER.

As the season is approaching when sunstroke is likely to occur, in 
both man and beast, a few words on the subject may not be untimely. 
In the so-called cases of sunstroke, we may have three different 
varieties, and produced in two different ways—direct sun rays and effect 
of high temperature. 
The varieties are, first, those cases simulating cerebral meningitis , or 
inflammation of the membranes of the brain ; second, cases of exhaustion 
from the effects of heat (no brain symptoms, but debility both muscular 
and vascular) ; third, a mixed variety of the two forms. It is necessary, 
of course, to make out the form of attack, with a view to treatment. 
The meningeal variety requires opposite medication, as a rule, to the 
cases of exhaustion, while the third or mixed form will demand a mod¬ 
ification that requires considerable professional tact to pursue. 
Bleeding has been strongly advocated, assisted by purgatives, in the 
meningeal variety, but this treatment does not always carry the cases 
through, even if seen early. Strong stimulation seems to be indicated in 
the exhausted cases, but the increase in temperature of the blood, as 
shown by the thermometer, must be a guide to treatment. During the
