958 Summary and Conclusions 



error and had previously trained himself in thermometric readings; 

 the thermometer remained five minutes under the tongue. Here is 

 the summary of his observations, made in the hills of Yorkshire: 



Table of M. Tempest Anderson. 



Time Height Temp. F. 



(Eng. feet) 

 In bed 7:30 900 97.7° 



Before starting, being cold 9:40 900 97.6° 



After a mile walk on the plain, and a rapid 



ascent of 1000 feet, tired, hot, sweating, and 



before stopping 11:20 1900 96.4° 



Seated, after 10 minutes, neither hot 



nor cold 11:30 1900 98.2° 



Rapid ascent to the summit, which I reach 



sweating, unable to breathe 12:00 2414 97.0° 



Seated, having eaten a little, and finding 



the wind cold 12:37 2414 99.3° 



Rapid descent of 1000 feet, hot, without 



stopping 1:10 1400 98.0° 



Crossed the valley to climb Grageth; after 



an ascent of 500 feet, hot, sweating, and 



without stopping 2:17 1900 96.4° 



Seated 2:24 1900 97.6° 



Seated, cold 2:33 1900 98.6° 



At the top of Grageth, walking slowly __ 2:52 2250 98.2° 



Seated, cold *. 3:12 2250 98.4° 



After descending rapidly 1000 feet 3:55 1200 98.0° 



Seated 4:05 1200 98.0° 



At the inn of the "George and Dragon" __ 9:50 500 97.9° 



So the minimum temperature of 96.4 was observed during the 

 ascent, sweating freely, with a sensation of heat. 



I agree with Dr. Marcet, that it is the fact of the ascent and not 

 the altitude in itself that influences the temperature. 



A single theory can, according to M. Anderson, include appar- 

 ently contradictory cases, like those of M. Marcet and M. Forel. 

 The human machine, he says, has not the same output in all men. 

 The quantity of heat necessary for the work of the ascent can in 

 certain individuals be developed through greater activity in com- 

 bustion; it may be that others are incapable of this increase of 

 oxidation: 



In the first class one would place M. Forel; in the other, that of 

 persons with weak powers of combustion, I place myself in the hon- 

 orable company of Doctors Marcet and Lortet.
