mperatures which this instrumentindicates are proportional to the quantities of heat which it receives. Hence,if in the above experiment a plate of glass causes the temperature to rise 1°and a plate of lead 6°, it follows that the quantity of heat reflected by thelatter is six times as great as… … By this method Leslie determined the reflecting powers of the followingsubstances, relatively to that of brass, taken as 100 :— Polished brass . . 100 Indian ink Silver • 90 Glass Steel . 70 Oiled glass Lead . 60 Lampblack The numbers only represent the relative reflecting power as comparedwith…
