This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1885 edition. Excerpt: make it unnecessary to cover the eyes; the pupils were obliged to state the number of beats made each time. The words employed in testing with whispered speech were exclusively the numbers from 1--99. They furnish sufficient variety to permit the formation of an opinion respecting the power of understanding speech generally. I also have convinced myself, especially during these examinations of large numbers, that we should by no means expect, in continuing to employ the same words, successively easier guessing. On the contrary, this fault, all the children knowing that they are tested for numbers, applies equally to all those examined, and hence can be disregarded. At all events, in using whole sentences, much more is liable to be guessed than with single words. Besides, it is found that certain words or numbers are not gradually guessed more easily on continuing the examination, but always some of their consonants are misunderstood or not heard at all by all the persons examined, until we have reached the limit of perception of the individual. It was these latter numbers which served mainly as the measure for ascertaining the limit of audition. Besides the number 100, which in proportion to all the other numbers is heard at too small a distance, it was the numbers 7, 5, 9 which were understood with the greatest difficulty both at the beginning and at the end of double numbers, and therefore always had to be interposed again between the other numbers. 5 (in German " ftinf") and 7 are always mistaken for each other or for 6 until we are at the limit of audition; 5 as a rule is heard at a smaller distance than 7.
