by exposing black-bulb thermometers, are obvious and well known; never-

identical in construction, exposed in the same manner, and rejecting all 
observations in which the result could be affected by wind, results compar- 
able inter se might be obtained. It is believed that if the first condition 
could be secured this inference would be found correct, but in point of fact it 
is a matter of extreme difficulty to obtain the requisite identity of construc-
