Determination of the Law of Extinction of the Moons liadiant Heat in our Atmosphere. 
As, apart from any a priori consideration, an examination of the former observations 
had shown that the quantity of heat reaching us from the moon was dependent upon 
her zenith-distance, it was necessary that the whole of the new observations should be 
carefully examined in order to determine the law of this dependence. But since the 
moon’s phase and distance from the place of observation and from the sun’s centre are 
constantly changing, the observations had to be freed from the first two of these sources 
of change before they could be used for deducing the corrections dependent upon the 
zenith-distance. 
The necessary elements for the corrections were obtained as follows. The moon’s 
* March. 24. — The sky rather hazy all night, hut the observations were only taken during - the clearer intervals.
