Some observations made in North-Greenland 1923. 43 
years been exposed to strong decay, which had lessened already now 
their sharpness, still not to such a degree, that the exactness of the 
measurements is influenced. 
The diminuation of the glaciers as well in extend as in thickness 
since 1897 was very obvious. From stat. I it was now impossible to 
make tangential aims to the southern glacier (Mercanton: Lyngmarks- 
bræ), and from.the same point glacier number 2 at the western side 
of the valey (Mercanton: gl. Petersen) could no more be seen. I wish to 
set forth some remarks regarding the annexed tables À &B, which ought to

be compared with the tables X and XI of M. о. G. XIV. In the same 
way as in the latters I have again marked the measurements from 
stat. I with stippled lines and those from stat. II with full lines. As 
zero I have used the same point as in 1897 viz. a sharp fall at the edge 
of Unartorssuak (Lyngmarksfjeldet). I have marked the present limits _ 
in 1897. From stat. I the aim to stat. II is 170°31’ (not marked in the 
tables). 
It ought to be observed regarding stat. I, that aim 21°25’ does 
not regard the edge of the glacier, but the point where the glacier is 
disappearing behind the projecting soil. Aim 45°41’ regards the extreme 
point of a (lateral) moraine, which was not observed in 1897. Aim 
66°50’ is probably a glacier-port. Aim 70°30’ does not indicate the edge
