3, On the Heat altained by the Moon under Solar Radiation ; by Mr. 
aP. Harrisoy.—On the assumption that the moon’s crust is constituted 
geologically like the earth different parts of her surface would not attain 
d of 
days, after being subjected to the most intense cold during the moon’ 
insufficient for an surplus heat to have been absorbed, even if the region 
had been favorable for storing radiant heat. A 
ter, on the other hand, the surface illuminated will have been heated 
¢ 1 i 
+a good absorber of heat. The heat of the moon at the last quarter 
might, on like grounds, be shown to be greater, or certainly not Jess, than 
corresponding region in the first quarter is rather more than fifteen 
One; the measure being the duration of solar radiation, without refer- 
ence to the surfaces on which it falls.
