5. Maximum diameter between the two great trochanters of the thigh- 
bones. 
6. External conjugate diameter of the pelvis—From a point behind 
midway between the posterior superior iliac spines to the upper and fore- 
part of the pubic symphysis in front. 
Measurements of Chest. 
Circumference (taken with tape). 
Direct subject to hold his arms straight up over his head. 
Pass the tape round horizontally at the level uf the junction of the 
fourth rib-cartilage with the sternum or breast bone, then lower arms, and 
holding tape tightly, note circumference at— 
7. Deep inspiration ; 
8. Complete expiration.—This latter is easily attained by asking the 
subject to count twenty aloud quickly without inspiring. 
Before removing tape, mark the level with a blue pencil around the 
chest. 
The fourth rib can be found by noting the projecting ridge on the 
front aspect of the upper part of the sternum and taking the second rib- 
cartilage below this. 
Diameters (taken with callipers). 
9. Antero-posterior from mid-line in front to mid-line behind (sternum 
to spine of dorsal vertebra) at the level of the blue Jine previously marked. 
10. Lateral.—The maximum lateral diameter found with the callipers 
held horizontally and blades tangential to side of chest at the level of the 
blue line before referred to. 
Both these latter measurements should be recorded : (1) in deep inspi- 
ration ; (2) in complete expiration. 
G. Upper Lins. 
1. Length of the upper arm.—From the outer margin of the acromion 
to the lowest point of the external condyle of the humerus, or prominent 
point on the outer side of the arm bone as it is felt on the back of the 
limb in the flexed elbow-joint. 
2. Length of the forearm.—From the lower margin of the external con- 
dyle of the humerus on the back of the elbow to the tip of the styloid process 
or pointed projection directed downwards from the lower end of the 
radius and easily felt on the thumb side of the wrist. This gives the length 
of the radius. 
3. Length of the ulna.—From the tip of the olecranon or point of the 
elbow to the extremity of the styloid process of the ulna, the pointed 
projection of bone directed downwards from the forearm on the little tinger 
side of the wrist. 
4. Length of the cubit.—The elbow joint being flexed, the measurement 
is made from the tip of the elbow on the back of the arm to the tip of the 
middle finger. 
5. Length of the hand.—Measured on the dorsum. The hand being 
dorsi-flexed, the position of the radio-carpal joint can be determined. 
Measurement made from this to the tip of middle finger. 
6. Length of the thumb.—From the base of the metacarpal bone to 
the tip of the thumb.
