Note 164 — Chapter XII

I may add that the hypothesis admits of corroboration from sources not mentioned by its author. For Archdeacon Farrar wrote in 1865:—“The neglected children in some of the Canadian and Indian villages, who are left alone for days, can and do invent for themselves a sort of lingua franca, partially or wholly unintelligible to all except themselves;” and he quotes Mr. R. Moffat as “testifying to a similar phenomenon in the villages of South Africa (Mission Travels).” He also alludes to the fact that “deaf-mutes have an instinctive power to develop for themselves a language of signs,” which, as we have seen in an earlier chapter, embraces the use of arbitrary articulations, even though in this case the speakers cannot themselves hear the sounds which they make.
