keeping of them before they can be taken out again. The five per cent which the bank gains, when deposits either of coin or bullion are allowed to fall to it, may be considered as the warehouse-rent for the perpetual keeping of such deposits.

The sum of bank money for which the receipts are expired must be very considerable. It must comprehend the whole original capital of the bank, which, it is generally supposed, has been allowed to remain there from the time it was first deposited, nobody caring either to renew his receipt or to take out his deposit, as, for the reasons already assigned, neither the one nor the other could be done without loss.

But whatever may be the amount of this sum, the proportion which it bears to the whole mass of bank money is supposed to be very small.
