Bd. l. I made in a piece of L ead a (maH Hole with a Pin, arhole bresdth iras the +2th part oE an Inch. FOF 21 oE those Pins laid cosether took up the breadtm oF halt an Tuch. Through this Hole I let into iny darkened Chamber a beam ot the Suns. Lisht, and Found that the Mados offTairs, Phred, Pins, Stras, and Cuch like Plen- der Tubstances placed inthisbeam ofLisht, ere consider- ably broader than ther ouolttobe, il the rarsot Liohe passed on by thele Bodies in right Lines. And particu- larls a Tlair ot a Mans Hlead, Wrhole breadth iras but the28oth part ot an Inch, beins held in this Liolit, ae the distance oF about telre Feet Erom theHtole, did cast a Phadorr irtrich at the distance oF Four Tuches Fiom the Flair was the sixtieth part ot an Tuch brond, thatis, abore tour times bronder than theHlair, and at the di- Cance oFtrro Feet From the Flair ras about the eiglt and trventieth part ot an Inch brond, thatis, tentimes broader than ihe Hair, and at the distance OFten FCCE rasthe ciohth part of an lnch broad, that is 35 times broader.
