Phe Bradorrs et scratches made in polisted plates ol
Glaso vere also much broader than they ousht to be,
and the Veins in polistred plates of Ctass did also cast the
like broad Badorrs. And theretore the great breadtt
oF thele Cadons procceds from Pome other cause than
the retraction oF tne AIT.
Vet the Circle Z represent the midale ofthe TTair; Fig. 1.
ADG, BETI, C FI, thrce cars passins by one side ot
the Fair at sereral distances; RNC, LOR, MPS,
chree ocher rays passins by the other side ot the Hlair at
che like distances; D, F, F and N, O, P, the places
irhere the cays are bent in their passase by thellai;
C, TI, Jand C, R, S, the places irhere the cars FaII on
a Paper CQ; ISthe breadth ofthe Madow ot theltair

these tvO rayS AI and VS is bent in passins by the
Flair, and turned aside From the Padom 1S, because it
any part of this Liont vere noc bene it would Fall on
the Paper within the Mado, and chere illuminate the
Paper contrary to experience. And because irhen the
Caper is at a oreat distance trom the FTair, the Madon
is broad, and cheretore the rars II and VS are at a
dreat diltance trom one another, it Follos that the
tlair aets upon the rays oF Light at a g0od distance in
cheir passins br it. But the action is Arongest on the
rars rrhich pals by at least distances, and erors weaker
and weaker accordingly as the rars pass by at distances
sreater and greater, as is reprelented in the Scheme:
For thence it comes to pals, that the Macdow of the
lair is much broader in proportion eo the distance ot
