Note 112 — Chapter II
Reading edition
Such instances as George Guest's Cherokee system, and the crude attempt of a Vei (West Sudanese) Negro, if genuine, are not here in question, as both had the English alphabet to work upon. A like remark applies to the old Irish and Welsh Ogham, which are more curious than instructive, the characters, mostly mere groups of straight strokes, being obvious substitutes for the corresponding letters of the Roman alphabet, hence comparable to the cryptographic systems of Wheatstone and others.
