Earth warmer than the air in ■winter, early spring and autumn, but 

 colder during the summer, are the results of observations made at 

 Copenhagen by Mr. Weilbach. On the year, the average excess of the 

 ground temperature above that of the air is almost the same as at 

 Chisvdck, the former being 1-11, the latter 1-13.
