Part of the Work was performed near the River of 
*Tornea-, whofe Diredion is the fame with the Meri- 
dian of Tornea ; the Coafts of the Gulph of Bothnia 
being found very inconvenient for that Purpofe. By 
the favourable Situation of Five Mountains they 
formed Eight Triangles, which took in Space enough 
for their Defign. All the Five Gentlemen obferved,' 
one after another, each Angle of thefe Triangles, 
fetting them down in writing feparately. 
They afterwards determined the Diftance between 
Xornea and Mount Kittis, under the fame Meri- 
dian, by a Balls, meafured on the River when frozen 
over, whofe Length was 7406 Toifes 5 Feet, by the 
firft Meafurement ,• and when meafured again, was 
barely Four Inches over. This Diftance between them 
they found to be 55>234 Toifes. 
The firft Part of their Work being thus finilhed, 
the next was to find the Difference of Latitude of 
thefe two Places : This they did by the Help of a Tele- 
fcope, fixed to a Sedor of Nine Foot, made at Lon- 
doUi by the Care and Diredion of Mr. George Gta- 
haniy to whom the Lovers of Aftronomy are indebted 
for the curious and well-contrived Inftruments he has 
fupplied them withal. The Star they obferved at 
Tornea (x.Draconis : They repeated their Obfer- 
vations three times, and the greateft Difference be- 
tween them was but Two Seconds: Removing to 
Mount Kittis, they took the fame Number of Ob- 
fervations, of the fame Star, without finding more 
than One Second Difference. The Refulc was, that 
the Amplitude of the Arch, in the Heavens, between 
Tornea and Mount Kittis, (allowing for the Precef- 
fion of the Equinox, and the Time elapfed between
