Note 140 — Chapter VI
Reading edition
The art here mentioned was first made known to Europeans by a Frenchman, M. Du Vigneau, in a work entitled "Secrétaire Turc, contenant l'Art d'exprimer ses pensées sans se voir, sans se parler, et sans s'écrire:" Paris, 1688: in-12. Von Hammer has also given an interesting paper on this subject in the "Mines de l'Orient," No. 1: Vienna, 1809. (Note to Marcel's "Contes du Cheykh El-Mohdy," iii. 327, 328: Paris, 1833.)
