In Sneffels Yoculis craterem kem delibat
umbra Scartaris Julii intra calendas descende,
audas viator, et terrestre centrum attinges.

Translation to French:

Descends dans le cratère du Yocul de Sneffels
que l'ombre du Scartaris vient caresser avant les calendes de Juillet, 
voyageur audacieux, et tu parviendras au centre de la Terre. 
Ce que j'ai fait. Arne Saknussemm

Translation to English:

Descend into the crater of the jökull of Snæfell, 
which the shadow of Scartaris touches (lit: tastes) before the Kalends of July, 
bold traveller, and you will attain the center of the earth. 
I did it. Arne Saknussemm

The massage contains 3 nonstandard runes:
, which Verne transliterates to g;
, to d;
, to k. however, in the latin text it appears as the qu in the words quem and quod.
As well ᛯ is transliterated as two m's.
