At 11 to 33 there are in this table two cases of unusual gi'owth 

 among the girls, viz., 6'1 and 4"9 inches in one year respectively ; and it 

 is remarkable that in the first case the girl grew only 0'7 inch in the pre- 

 ceding year, and in the second case the girl (a difi'erent one) grew only 

 0'9 inch in the succeeding year. No such remarkable case occurred 

 among the boys. After eliminating these two cases, the excess in this 

 period remains in favour of the girls, but after 13 it preponderates greatly 



among the boys : — 



Boj's Girls 

 From 11 to 13 the excess among the girls, averaging annually 3"2 to 41 inches 

 „ 13 „ 17 „ „ boys, „ „ 3-7 „ 24 „ 



7° Ti'eating the minima in the same way, those of the boys are uni- 

 formly lower than those of the girls up to the age of 7, viz. : — 



Boj-s Girls 

 From 1 to 7 the excess among the girls, averaging annually 1-7 to 2-1 inches 

 ,, 7 „ 11 „ „ boys, „ „ 1-6 „ 1-3 „ 



At 11 to 13 the minima of the girls are, like their maxima, exceptional; 

 showing that in these two years the growth of girls is not only excep- 

 tionally, but at both ends of the scale usually, in excess of that of boys. 



Boys Girls 

 From 11 to 13 the excess among the girls, averaging annually 10 to 1-8 inches 

 » 13 „ 19 „ „ boys, „ „. 0-7 „ 02 „ 



8° The following table would be of considerable interest if it were 

 based on a larger number of cases. As far as it goes, it shows that in both 

 sexes a rapid annual growth, of 3 inches or more, occurs chiefly between 

 the ages of 1 to 3 and 11 to 16, the proportion being greater among girls 

 at the latter age, while it is greater among boys between 4 and 11.
