ON ANTBROPOMETEIC INVESTIGATION IN THE BRITISH ISLES. 36| 



2. Length of the forearm.— 'Evom. the elbow-joint interval as defined in 

 No. 1 to the tip of the styloid process of the radius. 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. 



4. Length of the cubit. — The elbow-joint being flexed, the measure- 

 ment is made from the tip of the elbow on the back of the arm to the tip 

 of the middle finger. 



5. Length of hand. — Measured on the dorsum. The hand being dorsi- 

 flexed, the position of the radio-carpal joint can be determined. It may 

 be regai'ded as corresponding to the bottom of the angle which is formed 

 between the hand and the forearm. Measurement is 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. 



7. Length of the four fingers. — The three phalanges only are to be 

 measured in each case. The measurement should be taken when the 

 lingers are strongly flexed at the metacai'po-plialangeal or knuckle joints 

 from points on dorsal aspect immediately in front of knuckles. 



8. Breadth of the hand. — Taken across the knuckles. 



9. Maximum circumference of the upper arm. — The upper limb should 

 be straightened, but the muscles must not be contracted. The tape 

 should then be passed round the upper arm where this shows the greatest 

 girth. 



10. Maximum circumference of the forearm. — The upper limb should 

 be straightened, and the tape passed round the forearm where this shows 

 the greatest girth. The muscles should not be contracted while the 

 measurement is being taken. 



G. Lower Limc. 



1. Length of the thigh. — From upper edge of the great trochanter to 

 the margin of superior extremity of tibia on outer side of knee-joint. 



2. Length of the leg. — From the margin of the superior extremity of 

 the tibia on the inner side of the knee-joint to the tip of the internal 

 malleolus. This measurement gives the length of the tibia. 



3. Length of the foot. — Two measurements : {a) from back of heel to 

 extremity of second toe, counted from inner side ; (6) from back of heel 

 to extremity of great toe. Both measurements taken with the foot 

 resting on the ground. 



A tracing of each foot should be taken. 



4. Breadth of the foot. — Measured across the heads of the metatarsals, 

 i.e., from the prominent point on the inner side of the joint at the root 

 of the great toe to the prominent point on the outer side of the foot at 

 the base of the little toe, when the foot rests on the ground. 



.5. Circumference of the thigh. — This measurement is to be taken mid- 

 way between pelvis and knee. The limb should be straightened, but the 

 muscles of the thigh should not be contracted. 



6. Maximum circumference of the calf — The muscles should not be 

 contracted while this measurement is being taken,
