GREENLAND VOYAGE. 
I took the moon’s altitude,—the distance between 
the sun and moon,—noticed the time,-—and regis¬ 
tered tlie whole of these data,—being only assist¬ 
ed in the altitude of the sun, for calculating the 
effects of parallax and refraction : and even this 
I was obliged to repeat afterwards, for obtaining 
the apparent time at the ship. From extensive 
practice, however, these difficulties, in a great 
measure disappeared, (at least so far as affected the 
correctness of the different observations), and the 
same results, as to accuracy, were obtained as if 
I had had the usual number of experienced as¬ 
sistants. 
As a part of the eastern coast of Greenland 
was discovered by Henry Hudson, in 1607, (from 
latitude 72° to 73 f°) and as some insulated points 
have been seen by some of the whalers within the 
last few years, it is difficult, and indeed impossible, 
to ascertain what proportion of the researches of 
this voyage is original discovery. The position and 
form, however, given to this coast in our best charts, 
are so different from the reality, that the greater 
part, if not the whole extent of these investiga¬ 
tions, may perhaps be considered as a new coun¬ 
try. The errors in the longitude prove to be very 
great. It has already been noticed, that the land 
in the 75th parallel of latitude differs from the 
meridian given to it by the best charts, about 7°,
