Digiti Lingua Or the Most Compendious, Copious, Facile and Secret Way of Silent Converse Ever Yet Discovered, 1698
Kessinger Publishing, Jul 1, 2003 - Language Arts & Disciplines - 48 pages
This volume shows how any two persons may be capable, in half an hour's time, to discourse together by their fingers only, and as well in the dark as the light. The directions herein given are so clear and the method so extensive (yet both superlatively easy) that if six persons are in company (and each of them well versed in the design) yet two of them may discourse together, and the other four wholly ignorant of what they mean. Due to the age and scarcity of the original we reproduced, some pages may be spotty, faded or difficult to read. Written in Old English.
