result of an anthropometric survey of thirty of these eunuchs. His 
conclusions are — 
1st. In the case of individuals castrated before puberty, the ablation of 
the testicles determines an increase of stature. This increase is con- 
siderable ; the average stature of the eunuchs easily surpasses the average 
for normal men of the same ethnic group. 
2nd. The increase in length of the lower limb is the important factor 
in the general increase, the trunk developing relatively little. The pro- 
portion between the length of the lower limb and height is greater in 
eunuchs than in men of the same stature. 
3rd. The length of the upper limb of eunuchs is relatively greater, and 
absolutely much greater, than that of men. 
4th. On the other hand, the height of the head is relatively less in 
eunuchs than in men. 
5th. The maximum antero-posterior diameter of the cranium, which 
normally increases proportionately with increased stature, in the Skoptzys 
shows an inverse proportion. 
6th. The maximum transverse diameter also bears an inverse proportion 
to the increase of stature. 
7th. Castration retards the growth of the skull; it must also affect 
adversely the growth of the brain. 
8th. It retards or restrains equally the transverse growth of the 
forehead. The development of the frontal minimum, which in normal 
men is proportional to the increase of the stature, becomes inversely 
proportional. 
9th. The effects of castration are also seen in the development of the 
height of the skull (auriculo-bregmatic diameter). This development is 
normally inversely proportional to the total stature. This order of growth 
persists, but it is retarded. 
10th. Castration retards, and probably ultimately arrests, the lateral 
development of the face (represented by the bizygomatic diameter), and 
also, probably, its vertical height. It is especially the lower part of the 
face which is affected, and probably more especially the height of the 
inferior maxilla. 
11th. In the Skoptzy eunuchs the region of the ophryon appears less 
developed. 
12th. Castration causes an arrest in the growth of the nose, especially 
in height. 
13th. It appears, on the other hand, to produce an increase in the depth 
of the orbit.
