are completely glabrous ; the voice is small, and surprisingly infantile. The 
breasts are large, the pelvis is very wide. Examination of the genital 
organs show them to be extremely rudimentary; the skin is slightly 
pigmented and hairless. The penis is well formed, but is hardly as big as 
the little finger. The testicles are of the size of sparrows’ eggs, and devoid 
of normal sensation. The patient has never experienced sexual desire. 
Observation A 2 (1). 
Y, aged 53, is thin and tall. His height is 1777 mm. The lower limbs 
are disproportionately long. The pelvis is broad. The genital organs are 
abnormal ; the scrotum is small ; the penis is very small. The right testicle 
feels like a small bean ; the left is quite impalpable, owing to the presence 
of a scrotal hernia. At the operation for the hernia it was seen to be small, 
about the size of a pea, and fibrous. 
Observation A 3 (1). 
Z, aged 38, is unusually tall. His height is 1782 mm. His lower limbs 
are very long relatively to his height. The pelvis is very broad. The 
penis is smaller than usual ; palpation of the scrotum reveals the presence 
of two very small and completely insensible testicles. There is no sexual 
desire.

From these measurements tables showing minimum and maximum 
percentages of excess of length can readily be constructed in the manner 
employed in Tables XX. and XXV. 
These tables show that individuals X, Y, and Z, who possessed function- 
less testicles, were the subjects of an abnormal development of the long 
bones of the appendicular skeleton. The excess of growth was more 
marked in the tibia than it was in the femur, and more marked in the 
radius than it was in the humerus. It is clear that the method of com-
