amount of the debit and credit fides of the account, and take their difference; then if the debit fide be the heavier, that difference fhews the fum due you by that perfon; but if the credit fide be the heavier, the difference is the fum you owe him. Laftly, debit or credit the account for the difference (as the cafe requires) to or by balance, debit or credit the balance account accordingly, and that account is clofed.

4. In the various accounts kept with foreigners, wherein exchange is concerned, two columns for the feveral amounts of drafts and remittances are used, the inner column, for the foreign money, and the outer one for your country currency. And by reafon of the conftant fluctuation of the rate of exchange, a confiderable profit or lofs may arise therefrom.

5. Balance the inner columns firft, valuing the difference at the proper rate of exchange, and carry the fame to the outer correfpondent column; then debit or credit the account and that of balance, as above. Now if the outer columns be unequal, as generally happens, take their difference, and debit or credit the account for that difference, to or by Profit and Lois, and carry the fame to that account, being the fum you have gained or loft by the rife or fall of exchange; and then that account is closed.

Imaginary Accounts.

6. The inferior imaginary accounts, fuch as Infurance Charges, &c. are all clofed by the aid of Profit and Lofs account; that account itself is clofed by the aid of Stock Account; and laftly, balance account is also closed by the aid of Stock Account, and the difference of the total of the two fides in balance account, fhews the nett ftock or whole property; provided the debit fide be the heavier, but if the other be the heavier, the difference is the negative property. -Stock account clofes of itself, if all be right.

Then the inventory for a new fet of books is made out from the balance account.

THE following Errata has been discovered in the different fheets as they came from the Prefs; if any other have escaped notice, the Author hopes the friendly eye of the literati will not pass them over without making a remark, and informing him thereof, that they may be corrected in the next edition.
