Feet. Also symmetrical. 
Tarsus. The external and middle cuneiform bones are probably absent. 
Metatarsals. 5th alone present. 
Digits. A small and very much curved little toe only is present ; it probably has 
the normal number of bones in it. 
For photograph of hands and feet : see Plate XXVI, Fig. (xi). 
Thos. IF. Wh. V. 31 (P. P., then unborn). Hands resemble those of his brother (V. 30) in 
every respect : but have more marked grooves between metacarpal heads. 
Feet Right 
Tarsus. The presence of the middle and ex- 
ternal cuneiform bones is doubtful. 
Metatarsals. 5th alone present. 
1st present, rudimentary. 
Digits. 5th alone present and curved. 
Small mass of fibrous tissue overlies 
the rudimentary 1st metatarsal. 
Left 
Apparently normal. 
Probably a rudimentary 1st. 
5th present. 
5th normal in number of bones, but 
curved. 
This child is only five years of age and it is difficult to say with any degree of certainty which 
bones are present and which absent in the case of the carpus, tarsus and the metacarpal and 
metatarsal bones. This is true also of the following case. 
For photograph of hands and part of feet : see Plate XXVI, Fig. (xii). 
R. Wh. V. 32 (P. P., then unborn). Hands and feet deformed. 
The hands are symmetrical and probably have the trapezium, at least, absent. Either the 
inner two or three metacarpal bones are present, but are badly developed, except the innermost. 
One digit, the little finger, alone is present, and has the usual three bones ; it is very much 
curved. 
The feet are asymmetrical. 
Right Left 
Possibly normal, though the cuneiform bones are not palpable. 
Tarsus. 
Metatarsals. 
Phalanges. 
1st rudimentary, 5th normal. 
Three bones in 5th digit. 
1st and 5th present. 
The first toe is long, and apparently 
composed of two bones. 
The little toe is as long as a child's 
middle linger, perfectly straight 
and without a nail. Three bones 
present. 
For photograph of hands and feet : see Plate XXV, Fig. (viii). The photo does not give a 
proper idea of left foot which looks more as in diagram. 
— Wh. V. 33 (P. P., then unborn). An infant, three months old. Hands and feet deformed, 
the deformity of the hands resembling those in V. 32. 
The feet both show a well-developed little toe, and a mal-developed great toe.
