lower part of the spathe pap gl warm, so that on thrusting 
the bulb of a small thermometer down into it the mercury is raised 
five or six degrees. The fo silo owing are some of the temperatures of 
different individuals, which we have taken for several years past 
with common thermometers :— 
Temp. of atmosphere : raised by Arumto | Temp.of atmosphere: raised by Arum to 
65° { 450 out of dors, | 80° (in vinery.) | 50° Nem 
59° 65° 58° ) 
56° 61° 58° mt ose 
60° 73° 54° ; 80° gers 
68° 75° 54° 84° do. 
58° 62° 74° (in room) 88° (in room.) 
56° 60° (in spathe.) 
The best of these observations show that the spadix was from 
12° to 30° above that of the atmosphere, and these readings 
the common sy um a oh a temperature of 7° R. or 473° F. above 
that of the atmosphere, and the Arwm cordifolium in the Mauritius 
has a observed to obtain a temperature of 44° to 49° R. or 181° 
upon a table or piece of glass, it quickly damps it as with steam. 
These interesting phenomena are, as Prof. Henslow remarks,
