1739 Excerpt: ...---Hereby, which "is very wonderful, one may often
discern in one "Line more Truths than could be contained in "whole
Volumes, if they were explained and de-- mbnstrated by the
Synthetic Method. Hence "it is, that by viewing one single Line, we
may' "learn almost whole Sciences in the Space of a 4t few Minutes;
which Men could scarce compre"hend otherwise in as many Years. The
