NOTE ON THE 31 AP OF GREENLAND. 



I may say that 31. Chajjclain is the real author of this map, 

 because he gace it as his opinion that it teas absolutely neces- 

 sary fur the illustration of my narrative, and I could not do

 or end, M. Gassendy {to lohom I had recourse touching this 

 difficulty, and whose capability is knoivn among all those who
