that it is only a small portion of the precipitation which falls in the 
form of rain. This is of no small importance, because large portions 
of the snow do not, like the rain, distribute themselves evenly over 
the land, but when the drifting takes place collect in larger and 
smaller drifts in certain localities sheltered from the northwesterly 
winds, whereas the stretches particularly exposed to the wind are

begins. 
The quantity of clouds above Danmarks Havn is largest in 
January, smallest in April. Upon the whole it is greater in the winter 
months and in June and July than during the remainder of the year. 
As far as the winter months are concerned, the greater quantity of 
clouds, in a very material degree, originates from the snowstorms, 
in other words from a circumstance not peculiar to the outer coast 
(Danmarks Havn). As far as June and July are concerned, the 
greater quantity of clouds originates from fog and, as mentioned 
above, we do not find this to the same extent at a greater distance 
from the coast. 
The forms of clouds are of less interest as a climatological 
factor. Considering the importance of the matter from the point of
