John Batchelor,
An Ainu–English–Japanese Dictionary
(1905)
“ But does the close resemblance between some of the words found in ancient Japanese and Ainu vocabulary tend to unify or in any way prove the two races to have been originally one? The reply is “yes” and “no.” In the sense now generally meant by races being one, the verdict must, I think, be “no,” certainly. If, however, we go back far enough,—if, for example, we travel back to the time of the confusion of tongues,—to the time when people were fewer and the continents as now found not existing—we may reply, “yes.” ”
