Note.

(c) It was with these however that I set out a great many
years ago: — and of these a considerable variety had presented itself to
me, each of them promising to be of itself adequate to the intended
purpose. —

I will subjoin an extremely summary but comprehensive
view of them, rather for curiosity than use. —

1. Employing a stamp in one or more places, for framing the
letters expressive of the sum. — Colour might be used with the stamp,
not so much by way of security against obliteration (it being but a
precarious one) as to render the letters more conspicuous in common use. —
The protuberance produced by the stamp could not (it is supposed) be
reduced for the purpose of falsification: at least if such a degree of depth
were given to it as might be given to it. — Among the particles forced
in, some of them being borrowed as it were from parts of the paper
more and more distant, according to the depth of the impression, could
not afterwards (it is supposed) be restored. For rendering the absence or presence
of the protuberances the more discernable, it might perhaps be
better that, in one place at least, no colour should be employed. —

2. To increase the difficulty, of obliterating the genuine letters, and
inserting spurious ones without laseration, a stamp producing perforations
might be employed for tracing out all or some of the letters, with or
without a stamp of the ordinary or simply-impressive kind. Whether
the texture of the Paper employed will bear in a degree sufficient for
use such solutions of continuity (to borrow a word from surgery) is in a
way to be proved by experience: punctures (with what precise view
I do not exactly apprehend) having of late been discernibly disposed in two
