Sitting Height. 



The sitting height varies ia the males from 33 to 39 inches, the mid- 

 sitting height being 35 inches, while at the "ioth grade it is 344 inches 

 and at the 75th grade 364 inches, giving a probable deviation of 1 inch. 

 In the females the sitting height varies from 30 to 36 inches; the mid- 

 sitting height is 338, the 25th grade 32'4, the 75th grade 342 inches, 

 giving a probable deviation of "9 inch. The following is the detailed 

 table of results : —

Span of Abms. 



The span of the arms in the males varies from 64 to 7G inches ; the 

 mid-span is 6l)8 inches, the 25th grade-span is 67-4! inches, the 75th 

 grade is 7 15 inches, and the mean deviation is 2 inches. In the females 

 the span varies somewhat more, measuring from 56 to 71 inches. The 

 mid-span is 62' 7 inches, the 25th grade-span is G0"5 inches, the 75th 

 grade-span is G45 inches, and the probable deviation is 2 inches. The 

 span exceeds the statdre in by far the greatest majority of males — indeed, 

 the reverse obtains in only eight cases, while in four the two measure- 

 ments are practically eqnal. The mid-stature of the males is 67 inches, 

 while the mid-span is 698 inches, .showing a difference of nearly 3 inches 

 in favour of the span over the height. In the females the statm-c in the 

 greater number of cases equals or exceeds the spaii, so that while their 

 mid-stature is 638 inches their mid-span is only G2"7 inches. These 

 results correspond to those of the Laboratory at the Health Exhibition, 

 taken from a much larger number of cases than the present. At the 

 Health Exhibition it was found that the mid-stature of the males was 

 €79 inches and the mid-span 698 inches, while in the females the mid- 

 stature was 63'3 inches and the mid-span 63 inches. The following tables 

 give the analyses of the span in the two sexes : —
