the insertion of the flexor tendon. The curve on the upper side of 

 the claw is part of a circle with a radius of about 60 mm. On the 

 radial side is a marked vascular groove, which runs nearly to the 

 point. The claw appears to have been able to move on the phalanx 

 through about 60. The greatest length is about 105 mm. 



The 2nd metacarpal measures 80 mm. in length, and 39 mm. in 

 breadth at its proximal end and 35 mm. at its distal. It articulates 

 proximally with the small 2nd carpale. The upper side of the distal 

 end has the articular surface extending back for 20 mm., so that the 

 1st phalanx could have been bent back to about 75. 



The 1st phalanx is a short powerful bone measuring 42 mm. in 

 length. At the proximal end it measures 30 mm. in width and 

 28 mm. in depth. The distal end measures 28 mm. in width and 

 20 mm. deep. 



The 2nd phalanx measures 35 mm. in length. The proximal end 

 is 25 mm. by 25 mm., and the distal 23 mm. by 20 mm. 



The terminal phalanx probably measured 65 mm. in length and 

 the proximal end 20 mm. by 32 mm. 



The 3rd digit is rather more slender than the 2nd. The meta- 

 carpal is 75 mm. long. The proximal end is 38 mm. wide, and the 

 distal end 30 mm. The articular surface on the distal end does not 

 extend down the upper surface as in the 2nd metacarpal, and the 

 1st phalanx could probably not bend back more than 25, nor could 

 it have been flexed more than 30. 



The following are the measurements of the phalanges of the 3rd 

 digit :-

1st phalanx 32 mm. 24 mm. 18 mm. 22 mm. 13 mm.

Claw phalanx ... 43 ,, 14 ,, 20 



In the 3rd digit very little extension beyond the straight was 

 possible, and the amount of flexion was limited to about 45 

 in the case of the claw, and about 30 in the case of the 

 phalanges. 



In the best-preserved foot the 4th and oth digits seem to have 

 been affected with arthritis, and the phalanges are deformed. In 

 this left foot the 4th digit has only one phalanx and the 5th two. 

 In the right foot the 3rd digit has evidently had the toe cut off 

 beyond the 1st phalanx, as it alone remains, and the distal articular
