Sexta and Quinta [9 to 11 years]. The quality of work did, indeed, become poorer in all classes, al- though the maximal number of errors was by no means made in the last study period. The decline in quahty was also much more rapid in the lower than in the higher classes. The method is, of course, open to improvement. Ebbinghaus is quite right, for instance, in conclud- ing after his experiment that the time allowed for supplying the elisions was too long. His experi- ments, it must be remembered, were all preliminary experiments, and, imfortunately, the test proper that was to follow them was never carried out. Moreover, despite Ebbinghaus' proposals {Neue Methode, 47 f.), the most serious difficulty still re- mains—that it is even less possible than in the case of dictations to work out any very large number of texts of equal difficulty, or to recognize and make due allowance in computing results for either these un- *Tliis example, from the translator's Manual, p. 448, is substi- tuted for the German text.
