In the case of the other points similar syllogisms have been set 
up. The examples given, however, ought to be sufficient to show 
and justify the manner of proceeding used. | 
(Аз to the uncertainty of certain figures of altitude, which in 
the map stand on the border line between inland ice and land, see 
the following chapter). 
Notes to the geographical maps. 
The result of the geographical survey is represented in the 
three sheets: Nordøst-Grønland, Nordlige Blad, Maalestok 
1:1000000 (Pl. IV), Nordøst-Grønland, Sydlige Blad, Maale- 
stok 1:1000000 (PI. V), as well as the somewhat more detailed 
Nordøst-Grønland Ёга 7 6°09'’ til 78° Nordlig Bredde, Maale- 
stok 1:500000. The symbols used are intelligible, either directly 
or by means of the explanation of symbols to be found on the maps 
themselves. For those who might wish to penetrate deeper into the 
knowledge of the maps, a few supplementary remarks will, however, 
be necessary. 
Scale. In the case of material so heterogeneous as that of the 
Danmark-Ekspedition it was impossible to fix the ratio of the scale, 
simply by taking into consideration the accuracy of the measuring. 
The consideration that certain details which might be of interest 
should not be too indistinct in the maps became, under these circum- 
stances, our reason for adopting the scale of 1: 1000000. In the im- 
mediate surroundings of Danmarks Havn, which was the object of 
the personal and frequently recurring researches of the scientists, a 
demand quite naturally arose as to the representation of a great 
number of details in the map. Further, such a great number of 
names sprang up in this locality that if only to find room for these 
it became necessary to make a special geographical map on a larger 
scale (1 : 500000). 
The projection for the two sheets in 1 : 1000000, is the con- 
form conical one. The 79th parallel is the developing parallel of 
both sheets. 
The somewhat detailed computation of the geographical network 
I shall here leave out of the question altogether. On the other hand 
a remark as to the normal scale affixed to the sheets of the map 
may not be out of place. 
If we put the ratio of the scale at the developing parallel (79°) 
altitude at 17.0. This principle would, however, be subject to the serious draw- 
back that the majority of people would not get any direct impression of the 
altitude.
