24. Proportions ivhich the Tipper Limb hears to the Stature and to its 

 different Segments, and the ')nean lengths of the latter. 



(a) The proportion -whioh the -whole upper limb bears to the stature 



in the males is 43-2 per cent. 



(b) The proportion wliich the length of the cubit bears to the stature 



is 26-7 per cent, in the males and 25-9 per cent, in the 

 females. 



(c) The lengths of the three segments of tlie upper limb as obtained 



by subtraction from the corrected means of the last three 

 measurements (21, 22, and 33) are as follows : — 



Males Females 



Upper arm ...»', ^ 283-1 — - 



Forearm 265-6 244-4 



Hand 1929 1739 



(d) The pi-oportion which the length of the upper arm bears to the 



stature is 16"5 per cent, in the males. 



(e) The proportion which the lengtli of the forearm bears to the 



stature is 15-4 in the males and 15"1 in the females. 

 (/) The proportion which the length of the hand bears to the 



stature is 11-2 in the males and 10-8 per cent, in the females. 

 (g) The proportion which the length of the forearm bears to that 



of the upper arm (the latter being taken as 100) is 94-5 per 



cent, in the males. 

 (h) The proportion which the length of the hand bears to that of 



the forearm (the latter being taken as 100) is 72"6 per cent, in 



the males and 71 "1 in the females. 



25. Span of Arins. — This is measured across the back, while the arms 

 are extended at right angles to the long axis of the body. 



26. Maximum Bihumeral or Shmdder Breadth. — This gives the greatest 

 breadth of the shoulders, and is measured between the most prominent 

 external surfaces of the deltoid muscles. 



27. Maximum Bitrochanteric or Hip Breadth. — This is the greatest 

 width from the external surface of the trochanter of the one femur to that 

 of the other measured while the subject stands erect with the fee close 

 together and parallel.
