§ MR. WELBYasked the Postmaster General, If he will state to the House, with special reference to invoices, orders, and similar commercial communications, what writing may, and what may not, be sent under halfpenny book-post wrappers?
§ LORD JOHN MANNERS, in reply, said, that they would be admissible at the halfpenny rate of postage only when they were not in the form of letters.
