only P art more than ~ of the whole altitude of the 
triangle. And this is the limit for the fteepeft kind of 
1 5 . Let us find now the particular values of the mea- 
fure of attraction arifing by taking certain values of n 
varying by l'ome fmall difference, in order to difcover 
what part of the greateft attraction is wanting by ob~ 
ferving at different altitudes. 
1 6. And firft ufing the value of n (’25 1 999) as found 
in the 14 th article, the general formula in Art; 13, gives 
sa x 1*0763700 for the meafure of the greateft at- 
traction. 
17. If n — T 3 -, or x - -f a ; the lame formula gives 
sa x i’07025i2 for the attraction at of the altitude, 
which is fomething lefs than the other. 
18. If n - ft = j ; the formula gives — x : 1 6 - 
for the attraction at -f or | of the altitude ; lefs again 
than the laft was. 
19. If n = ~ - t 5 ^e formula gives \sa x : 3 -
