OF that P ighE in Wrhich ther were held. Inthe Full red Tieht thes irere totally red rithout any sensible bluc or violet, and in the deep blue Lieht they ivere totally blue ithout any sensible red or vellor; and lo in the oreen Light ther vere totally sreen, exceptins a little Vello and. bluc, which iere mixed in the green Light ofthe Prilm. And comparino the fringes made in the Lereral coloured Lights, I Found that thole made in the red Light irere larsest, those made in the riolet vere least, and etiose made in the oreen vere ot a midale bionels. For the Frinses with wrhich the Madtorv OE a Mans Hair rere bordered, beins measured crols the Chadou at the distance oF six Tnches From theHtair; the distance betreen the midale and most luminous part ot the First Or innermost frinse on one side ot the Mado, aud that of the likre fringe on the other side ot the Ma- dorr, ras in the FuIl red Lishe;: oF an Tncl, and in the FuII violet . And the like distance betireen the midele and inost luminous parts of the second fringes on either side theador rras in the FuII red Lieht :, and in the violet= ot an Inch. And these distances ot the Fringes held the lame proportion at aI distances Fror the Llair writhout ans lentible variation. So then the cars wtrich made chele tringes in the red Liont passed by thetlair at a greater distance chan thole did which made the like fringes in tho violet; and there- Fore the FTair in caulins these fringes acted alike upon the red Lighe or least retrangible rays at a greater di stance, and upon the violet or most retransible rays at a lels distance, and by those actions dispoled the rec. Lighe into larger tringes, and the violet into smaller. and the Lishus oE intermediate Colours into tringes ot intei-
