It was thus observed whether or not he heard the tone at a greater distance than did the native; the distance at which the watch or the Politzer acuometer was audible to the experimenter always being the denominator of a fraction standing for the acuity of the native tested. Thirty-five natives were tested for hearing. Although the tests, as has just been indicated, were extremely rough, they served to show that Papuans, on the whole, do not hear as well as do Europeans, though some of the individual Papuans, indeed, heard better than did either Myers or Rivers. On their return to England, Myers compared his own hearing and that of Rivers with the hearing of other Europeans and these comparisons seemed further to confirm the relative inferiority of the auditory acuity of the Murray Islanders. Prom the second point of view of my measurements of hearing, the literature is voluminous. Anything like a comprehensive review of all of its phases would, therefore, at once carry us entirely too far afield. Indeed, it would be a bootless task, by reason of the diversity of methods employed and devices used, which it would be wholly impossible to place into any scale of equivalents. Very considerable work has been done on the continent of Europe in the way of establishing quantitative auditory measures. Something in the same direction has been accomplished in the United States, and Lord Rayleigh, in England, has pretty thoroughly broken the ground in the way of making it possible to determine the energy proceeding from certain sonorous sources. I shall not, at this time, attempt to review the merits of the variou...
