climbing, the general conclusion of which was that the tem- 
perature of the body increases during ascents or descents. 
In the same journal, p. 165 of the same volume, Dr. Thorpe 
has published the results of observations made upon himself 
during an ascent of Mount Etna, from which it appears 
that he noticed a small decrease of temperature. 
Dr. Anderson, however, Nature, vol. xii, p. 186, partially 
confirms the earlier experiments of Drs. Marcet and Lortet, 
who observed a decrease of 8 or f degrees F. in the tempera- 
ture of the body during mountain ascents. The greatest 
fall recorded by Dr. Anderson amounts to 1 0, 6 F. 
During the long vacation I carried out a few experiments 
upon my own body-temperature while rowing and while 
ascending a height. 
The observations were made with a registering clinical 
thermometer, the bulb of which was placed in the mouth 
underneath the tongue. The bulb was allowed to remain 
in this situation during five minutes before the readings 
were noted.
