§ 5.
The amount of the guarantee-deposit, which is on every occasion to be paid in specie, will be always fixed by way of ordinance.

§ 7.
Of the money paid into the Orders' (Cheque and Clearing) Service of the Post Office Savings Bank there will always be kept in hand a portion in specie adequate to meet probable needs.
