30 THE- ROYALE SOCIETY;OF CANADA 
The child was a typical chondrodystrophic dwarf. The trunk 
was about the normal size for his age, but, as compared with the limbs, 
disproportionately long. The umbilicus was situated below the centre 
point of the body. The legs were short, measuring twelve inches 
from the crest of the ilium to the sole of the foot. The defect was 
mainly due to abnormal shortening of the femora, though there was 
also slight curvature. The arms were short, measuring ten inches 
in length, the defect here being likewise in the proximal portion of the 
limb. The tips of the fingers reached only to the crest of the ilium, 
instead of half way down the thigh as in a normal individual. The 
trunk was well-formed and there was no lordosis. The abdomen 
was prominent. There was no beading of the ribs. 
The total height of the body was thirty inches, as compared 
with thirty-seven in a normal child of the same age. The head 
was distinctly hydrocephalic, measuring twenty-three inches in 
circumference, as compared with twenty-two in a normal child of 
the same age. As the head was larger than normal, also, in a vertical 
direction, it will be seen that the defective height of body was due 
to the shortening of the femora. The body otherwise was plump 
and robust. The anterior fontanelle was open, and the enlargement 
of the head was very noticeable posteriorly. The nose was broad, 
the root retracted. The mouth was broad and the child was apt to 
protrude the tongue. Dentition was very imperfect, and most of the 
teeth were decayed away. 
The fingers were plump, somewhat pointed at their extremities; 
the second, third, and fourth fingers were almost of the same length, 
and the hand showed the characteristic ‘‘trident’’ deformity. 
It is worthy of note that the second and third toes of the left 
foot were partially webbed. 
The mentality of the child was fair, though it was stated Ga he 
was slower in walking and talking than the other members of the 
family. 
Skiagrams showed that the femora and humeri were considerably 
shortened, and also somewhat curved, and that the ends of the long 
bones were distinctly enlarged. So far as I could tell, there was 
no ingrowth of the periosteum between the epiphyseal discs and the 
cartilages. 
As bearing on the possible etiology, it was interesting to learn 
that the first child of the family presented spina bifida: also, one 
maternal uncle was somewhat dwarfed, and another had the second 
and third toes of the left foot webbed. There was, however, no 
other similar case in the family, or among the forebears, according 
to the information of the parents.
