the places Marked in this Map, appears to be the 
fame which is delivered in the Obfervations that 
have been made in thofe very places, and with Cor-

know the Situation of this Ifland, in refped of the

We have here propofed Monfieur Sanfons Map,

be obferved in this Map, touching the Situation of 
the Coafts of LangueJoc and Provence , which come 
far fliort of Truth, as to the Elevations of the Pole, 
which may be eafily enough obferved.
