stadia we have already founded our calculations upon will bring us to the
latitude of 69° 27': the latitude of the southernmost point of Greenland is
very nearly 70°. But the description given by Pytheas of the productions of
the country by no means coincides with Greenland. At the same time, other
parts of his description agree with this country; particularly when he
says, that there the sea, the earth, and the air, seem to be confounded in
one element. In the south of Greenland the longest day is two months which
does not coincide with Pytheas' account; though this, as we have already
pointed out, is contradictory with itself.

Let us now consider what will be the result if we suppose that a different
stadia were employed: the next in point of extent to that on which we have
already founded our conjectures, (there being 700 equal to one degree of
the equator) will bring him to the latitude of 66° 8'; the latitude of the
northernmost part of Iceland is 66° 30', coinciding with this result as
nearly as possible. The description of the climate agrees with Pytheas'
description; but not his account of the length of the day, nor of the
productions of the country. Of the third kind of stadia, 833-1/3 were equal
to one degree of the equator; calculating that 1000 of these were sailed
during a day and night's voyage, Pytheas would arrive in the latitude of
55° 34', at the end of six days. This, however, is absolutely at variance
with the fact, that he took his departure from the northernmost point of
Britain, and would in fact bring him back from it to the entrance of the
Frith of Forth. It is supposed, however, that this is the real latitude;
but that the west coast of Jutland is the country at which he arrived. But
this obliges us to believe that his course from the northern extremity of
Britain, instead of being north or north-east, or indeed at all to the
north, was in fact south-west; a supposition which cannot be admitted,
unless we imagine that the ancients were totally ignorant of the course
which they steered. On the other hand, Pytheas' description of the
