17. Span of Arms. 



As compared -with the corrected mean height when standing, the 

 corrected mean length of span is 36 millimetres greater than that of 

 the stature in the males, -while in the females the span is shorter than 

 the mean stature by 14 millimetres. Taking the stature as 100, the pro- 

 portion -which the span of arms bears to it in the males is 100-2, and in 

 the females 99. In 9 males the span of arms was shorter than the stature, 

 but in all the others it -was greater. In the females, on the other hand, 

 in 27 cases the span of arms -was less than the stature, in 18 it was 

 greater, and in one case the two measurements were equal. 



18. Weight. — Owing to the weighing machine and weights having 

 to be got on the spot English pounds and ounces had to be used. The 

 figures of weight below are consequently pounds and decimals of pounds. 



19. Pull. — When the strength of pull of one arm and hand differs 

 from that of the other, a mean of the two arms has been taken as the 

 strength of pull of the person. 



The dynamometer being graduated to English weight the following 

 figures represent pounds and decimals of pounds.

In the males the right arm is the stronger in 28 out of 65 cases, or in 

 50"9 per cent. ; the two arms are equal in 16-4 per cent. (9 cases), and the 

 left arm is the stronger in 32-7 per cent. (18 cases). In the females the 

 right arm is the stronger in 23 cases out of 49 cases, or in 46-9 per cent. ; 

 both arms are equal in 28-6 per cent. (14 cases), and in 24-5 per cent. 

 ■the left arm is the stronger (l2 cases). 



■ 20. Vital Cafacitrj of the IyMW^.9.— This was ascertained by means of 

 Stanley's spirometer, graduated in cuhic inches, so that the following 

 figures represent cubic inches and decimals of cubic inches. 



21. Circumference of the Chest. — This measurement was only ascer- 

 tained on males. During forced inspiration the circumference of the 

 chest was as follows : —
