GROUP G. 
The Structural Peculiarities of Eunuchs. 
Observation C 1 (4). 
Skeleton of a Eunuch (a negro from the Sudan). 
Age at death, 24-25 years. 
Total stature of skeleton . . . 1790 mm. 
Allow for soft parts . . . . 30 „ 
Estimated stature of individual in life . 1820 mm. 
Relatively to the length of the bones of the appendicular skeleton, the 
axial skeleton is short. 
The long bones are exceedingly slender, of feminine type, and show no 
projecting crests for muscular attachment. 
The humerus is long ; the radius and ulna are definitely longer in 
proportion ; the metacarpals and phalanges are extremely elongated, so 
that the hand is almost simian in appearance. 
The femur is very weak, is devoid of its normal curve, and is unduly 
long ; the tibia and fibula are even longer in proportion, and are very 
slender ; the metatarsals and phalanges are very long and slender. 
The measurements of the longer bones of the limbs are recorded in 
Table XXXVI., column 2. The remainder of the columns of the table 
were worked out in the manner already indicated in connection with 
Tables XX. and XXV.

From this table it is obvious that, relatively to the total stature of the 
skeleton, all the bones of the limbs are unduly long ; those of the proximal 
segments, however, to a markedly less extent than those of the distal.
