has badly exprefied his own thoughts, for his tables 
make it that the equino&ial muft either fwell or 
contract itfelf. And this is very excufable in Ed- 
ward Wright, for at that time geometricians had no 
notion of Fluxions, or the increafe of magnitude by 
local motion. 
Mr. Weft and his editor have therefore fallen into 
this error ; they have taken the words but not the 
fenfe of Edward Wright, and the Critical Reviewers 
vindicate them, and make it as though this property 
had been communicated to the Royal Society by Mr. 
Weft, the particulars of which may be feen in the 
Review juft now mentioned. 
The propofeddemonft ration of this tangential proper- 
ty at page 58 of Mr. Weft’s book, is no demonftration 
at all, there is nothing more plain, than that, in order 
to have the meridians at equal diftances, the degrees 
of latitude muft be enlarged to the fame proportion in s 
every part, as the circular meridians are nearer to- .. 
wards the poles, which proportion is as the coline of 
the latitude to the radius.
