A Ready-Reckoner of the World's Exchanges. By J. H. Norman.

(Sampson Low, Marston, and Co.)—This is an account of the monetary system of many countries, more than one hundred and fifty. It cannot be mastered without some effort. Mr. Norman, like other experts, does net deb diffieulties quite as plainly as he might ; but that it will be very helpful cannot be doubted. A future edition might, we think, be improved by being prefaced with some danitions,—the technical word "par," for instance. It is not every one who knows even the literal meaning of the word. We wonder whether any one of our readers has ever been puzzled by the fact that an unquestionable paper security or a Bank-of-England note is worth more for exchange purposes than gold. It is the cost of transmission that gives the advantage. It costs more to send back five sovereigns from Paris to London than to send a .45 note.
