The above Table is that which is given by Mr. Gilpin in the 84th Vol. of the Philofophical'Transactions, and is of eflential ufe for taking the Specific gravities both of folids and fluids,by enabling the operator to reduce the weight or bulk of the diftilled water employed in anycafe to that which it would have at any other common temperature, and particularly to 6o°which is the ufual ftandard. Thus, for example, fince the Specific gravity of water at 47 0 . is1.0008, and .at 6o°. is 1.00000, (and consequently 10008 grs. at 47 0 are equal in bulk to 10000grs. at 6o°) it follows that it would require 252.708 grs. at 47* to equal the Space of a cubicinch; for 10000 : 10008 :: 252.506. (the weight of a cubic inch at 6o°.) 1252.708. The re-markable anomaly of the Specific gravity of water decreafing through all the degrees of tempe-rature below 40°. or thereabouts, that it remains uncongealed, has been noticed under the articleWater , but the difference for one or two degrees above or below 40° is fo trifling, that it hashardly yet been ascertained with perfeft accuracy.
