The above table shows the distribution by age and sex of the ¢“ habitual 
stutterers” in the Boston public schools in May, 1893. In calculating 
she percentage of stutterers I was obliged to employ the figures given in 
columns 2, 5, and 8, which stand for the number of pupils at each age 
belonging to the schools on January 31, 1893. The percentages printed 
full-faced type should be particularly noted, since it would appear that 
the maximum incidence of stuttering is not even relatively similar for 
boys and girls of a given age. The percentage of stutterers to total 
aumber of pupils is 0.78 ; that of boys who stutter, to total number of 
ooys, 1s 1.13, and the corresponding percentage of girls is 0.41. These 
results agree with the statements of various European observers; viz., 
that stuttering is about three times as frequent among males as among 
females. The table also shows, what has frequently been noted, that 
stuttering is most frequent at the period of second dentition, and at the 
onset of puberty, which are periods when the nervous system is specially 
susceptible to disturbance.

This table is comparable to Table I., but differs from it in that it is an 
analysis of the returns of the enumeration made January 31, 1894, and 
of that made May 1, 1893, combined. On January 31, 1894, the total 
aumber of stutterers in 65,686, the total number of pupils, was 498, or 
0.77 per cent. Of the total number of stutterers there were 376, or 
1.11 per cent., in 34,290 boys, and 122, or 0.40 per cent., in 31,396 
iris.
