[To me Emma or THE " SeEcricoa."1

Sin,—To the decimal system advocated in your last number there is one serious objection in the fact that a coin would be intro- duced half the sine of the smallest coin in actual use for many years. Consequently all the numbers used in our calculations would be immediately doubled. Oar second cask column would have three figures. If we made a double-florin our fundamental unit, divided into one hundred email units, we should have a mach simpler system. If the terms " dollars " and "cents" were objected to, we might say "doubles" and "quits" or "bits." Our second column would be reduced to two figures. Our numbers would not be doubled. Prices would run 25, 60, 8/25, 1/40, Ate. Only eight coins would be wanted—two gold (a sovereign, a half- sovereign), two silver (a double and a florin), two nickel (ten-bits, five-bits), and two bronze (two-bite and one-bit). The greatest objection would be that our present statistics would have to be reduced to the new basis. But we should only have to add men- tally a nought and divide by two: 677 sovereign. become 3,985 doubles. Surely to the statistician this is as easy as simple copying.—I am, Sir, Ac., Hums Jones. 20 Oaker Arena., West Didsburg, Manchester.
