28 ALE& HRDLIKA 



as to its position is given by the cutaneous fold of the lower part of 

 the abdomen in this situation. 



8. *Spinous process of the 5th lumbar vertebra: to ascertain this ana- 

 tomical landmark with exactitude, the subject shall be caused to bend 

 forwards from the hips, when the spinous process of the 5th lumbar 

 vertebra will become prominent. 



9. Sitting height: the subject sits on a horizontal and resisting seat 

 about 30 to 40 ctm. high (this height being proportionate to the sta- 

 ture of the subject) : the knees are flexed: the dorsal aspect of the trunk 

 is to make contact with a vertical plane, or with the anthropometric 

 rod at two points, viz. in the sacral region and again between the 

 shoulder-blades. The axis of vision is horizontal, as in No. 1 (supra). 

 The height of the vertex above the surface of the seat is to be measured. 



10. Pelvic height: the subject retains the position adopted for the 

 sitting height (No. 9). The height of the summit of the iliac crest 

 above the surface of the seat is to be measured. 



11. *Acromion: anatomical landmark: superior and external border 

 of the acromion process. 



12. *Great Trochanter: anatomical landmark: upper border of the 

 great trochanter. 



13. * Anterior superior iliac spine: anatomical landmark: the sum- 

 mit of the anterior superior spine of the ilium. In cases of difficulty, 

 the point is found by tracing Poupart's ligament to its iliac termi- 

 nation which defines the point precisely. 



14. *Elbow: anatomical landmark: the radio-humeral articulation. 



15. *Wrist: anatomical landmark: the tip of the styloid process of the 

 radius. 



16. *Tip of the middle finger. 



17. *Knee: anatomical landmark: upper border and edge of the 

 inner tuberosity of the head of the tibia. 



18. * Ankle: anatomical landmark: tip of the internal malleolus. 



19. Span: the subject is placed against a wall, the arms extended 

 horizontally, the palms of the hands directed forwards. Measure the 

 distance between the tips of the middle fingers of the two hands. 



If a wall is not available, the rigid anthropometric rod is to be placed 

 behind the subject, who assumes the position described in the pre- 

 ceding paragraph. The same measurement is to be made. 



In either case, the maximum span of the subject is to be recorded. 



20. *Bi-acromial diameter: maximum distance between the two acro- 

 mial points (cf. No. 11).
