300 REMARKS ON TRAVELS 
measured, that is to say, the shadow terminating distinctly 
and without the penumbra. The calculation gives for the 
latitude as nearly as possible nine degrees.* 
This being admitted, I perceived that the construc- 
tion (made in the manner before explained) of the line 
which represents the first part of the journey, gave to 
the situation of Time the same latitude within a few 
minutes. This agreement convinced me that no change 
was required in the construction 3 so small a difference, 
considering the insufficiency of the means employed, 
might indeed be regarded as an entire concordance, and 
I could not but suppose that it was probably the effect of 
a fortunate compensation for many errors on the contrary 
side. I might therefore look upon Time as a point nearly 
fixed, and leave it to establish the other two lines. The 
longitude of Time, resulting from the preceding opera- 
tions, is nine degrees two minutes west of Paris. Thus 
Tim^ would be at a nearly equal distance from the equa- 
tor and from the meridian of Paris.

obliging notice to Lieut. Col. Coraboeuf, of the corps of royal geo- 
graphical engineers.
