    acknowldedgment due to Truth and common juttice. The uvea, and that part of the uvea, by whole adion I fuppofe m the eye to he kept tenfe, is not invifible. Is tin's Gentleman acquainted with no Anatomift, no Profeffor of Phyfick, that can give him better information? But perhaps he is all this while thinking of mufclesor muf- bular fibres within the cryftalline humour. If in what follows n I have the hardinefs to ad¬ vance beyond the inftrudlions of my Mafter, as my Matter is neither troubled with envy nor ill na¬ ture, which is more than can be faid of all Matters, I am fure he will eafily pardon me* Had he laboured under any jealoufy of his difci- pie, he would never have beflovoed thofe profufe praifes, which fo much offend Mr. Robins, upon the Effay on diftind and indiftind Vifion. But in regard to thofe praifes, I mutt own, my Matter’s affedion, like Mr. Robins's, resent¬ ment, was fomething too hard for his judgment. Dr. Smith, it feems, 0 has chofe to be very con- cife in regard to the fits of eafy reflexion and tranttniffion of light, upon which I have adven¬ tured to expatiate. His vcompleat Syflem of Opticks, we are told, is upon this argument fo very deficient, that thefe alternate fits of reflexion and tranfmijfion of light are not fo much as mentioned by namey where he has undertaken to exhibit Sir Ilaac Newton’r difcoveries in Opticks.q There can hardly begiven a better inftance of the candour and ingenuous behaviour of Mr. Robins and his afiociates with regard to Dr. Smithy than this laft cited paffage, which hills fo naturally in my way.
