Observation A 10. 
Abridged Description of the Body of an Anorchid dissected at 
the Royal College of Surgeons in Ireland. 
Subject No. A 10. Age uncertain (between 20 and 30 ?), Male. Cause 
of death, Septic Peritonitis. Stature, 1675 
General Description (see fig. 4 b). 
The subject was thin and ill-proportioned, the most striking peculiarity 
of his form being the great breadth of the perineum, and the long slope 
outwards between the crest of the ilium, and the prominence of the great 
trochanter. The cheeks were hollow and the face small ; the skin freckled 
and glabrous. The penis and testicles were small. 
The first step in the dissection was to remove the testicles. They 
measured 28 mm. in height, 19 mm. in antero-posterior diameter, 16 mm. in 
transverse diameter, in place of the normal 45 x 25 x 20 mm. (38) of the 
average adult testicle. 
As in A 9, the examination of the body was divided into three parts : 
(1) Microscopic examination of the testicles and ductless glands ; (2) Dis- 
section of the body ; and (3) Examination of the macerated skeleton. 
The testicles were functionless organs. No material abnormalities were 
discovered in the course of dissection. 
The Skeleton— The skull closely resembled the skull of A 9 (see fig. 5). 
There was a similar failure of the development of the anterior part of the 
antrum of Highmore, with its consequent diminution in the breadth of the 
face and nasal height. A similar increase in the depth of the alveolar process 
of the superior maxilla and in the symphysial height of the mandible. 
The vertebral column was of interest. The ossification of the cervical 
and lumbar vertebrae was complete, whereas that of the dorsal vertebrae 
was incomplete, none of the dorsal epiphysial plates being joined.
