6oo Mr. Dalby’s Remarks cn Gen . Roy’s Account 
for, in pages 185. 187. we have 13574 6.3 and 1337684 fath. 
the diftances of Dunkirk north from Paris, the mean is 
l 337 S 7 -4 5 if from this we take 358.6, we have 133398.8, as 
in Ait. 10. ; but fiubt rafting 349.4, gives 133408 for what M 
is north of Paris, which added to 27248.2 there refults 
160656.2 agreeing with that in Art. 13. 
P. 190, 19 1. It will immediately be perceived, that the 
columns in the table of general refults here alluded to, have 
been filled by a method fimilar to that of working a travcrfe • 
The following table, however, was previoufly drawn up to 
facilitate the computations, and by which the numbers in the 
two firft columns of diftances may at any time be eafily exa- 
mined. 
This table will readily be underftood ; for, if we fuppofe 
parallels to the meridian of Greenwich to be drawn through 
the ftations on the left, oppofite on the right are the angles 
which the adjacent ftations make with thefe parallels.
