maximum is greater Фар the midsummer one must remain ап open 
question, though I must remark that the summer maximum shown 
in Fig. 14 is probably too small, as will appear from what is given 
below. 
In his explanation of the summer maximum WEGENER starts 
from the consideration that the lowest stratum in the air, the tem- 
perature of which, in July and the first two thirds of August, is 
practically always above zero, should give heat to the melting 
process going on during the whole of the summer. In this connection 
he refers to the fact that through the whole of the summer there 
are on the so-called snow-bare land here and there drifts of snow, 
that there is a greater névé on Germania Land, and in particular 
that the snow- and ice-bare area of land is very inconsiderable 
compared to the vast areas, which are covered by the adjacent 
inland ice and the still nearer sea ice. 
I cannot altogether follow WEGENER in this line of reasoning. 
The areas on Germania Land covered with perennial snow-drifts 
and névés are too inconsiderable to have any noticeable influence 
as to the atmospherical temperature of the summer. One might 
even be tempted to suppose that as the snow-bare land and the 
water in small lakes, watercourses and boggy tracts by means of 
the insolation would be heated considerably above the temperature 
of the air"), the lowest stratum of air which sweeps along the sur- 
face of the earth must receive some heat from the latter. The near- 
ness of the inland ice hardly plays any part in relation to the summer 
temperature at the surface of the earth; at least there is nothing 
which seems to suggest, that the summer should be colder nearer 
the ice border than along the coast. On the contrary. The coast 
sea which is full of floating ice is, on the other hand, of very great 
importance to the summer temperature near Danmarks Havn. 
In “Meteorologische Terminbeobachtungen am Danmarks Havn” 
WEGENER gives a summary of the frequency calculated in per- 
centage with which the various directions of the wind occur in the 
single months near Danmarks Havn. From WEGENER's summary I 
have made the table given below, where under the column “land 
wind”, that is wind which comes to Danmarks Havn from land, I 
have collected the directions N, NW and W, whereas the column 
“sea wind” comprises the directions S, SE, E and NE. Wind from 
SW, which comes to Danmarks Havn from Dove Bugt, does not 
show the marked characteristics of the sea wind, and is probably
