Hereditary Split-Foot or Lobster-Clem 
border of the hand is due to a displaced phalanx, or to two phalanges fused and displaced*. The 
hands as in the majority of cases show poor muscular development ; the five metacarpals are 
palpable on the left hand. 
Hands 
Carpus. Apparently normal. Normal. 
Metacarpals. 1st absent, 2nd rudimentary, 3rd Normal but the middle three are de- 
rudimentary, but larger. fleeted towards the thumb. 
4th and 5th of normal length. 
Phalanges. In both hands a bone is felt lying between the heads of 4th and 5th meta- 
carpals, probably a phalanx of ring finger : see diagram above. 
5th digit shows three phalanges. 1st digit rudimentary. 
5th digit, three phalanges. 
The feet show the same deformity as those of Eliza Wh., his sister. 
For photograph of hands : see Plate XXVII, Fig. (xvii), to right. 
Henry Wh. V. 18 (P. P. IV. 6). Hands and feet defective. Hands have one digit only on 
each ; feet resemble those of his sister, Eliza W/t., V. 16. 
Hands, symmetrical. 
Carpus. Trapezium and trapezoid bones probably absent in both hands. 
Metacarpals. 3rd metacarpal probably present but very imperfectly developed. 
4th metacarpal better developed. 5th metacarpal normal. 
Digits. 5th only present on each hand, much curved, and joints partially anky- 
losed. 
For photograph of hands : see Plate XXVII, Fig. (xvii), to left. 
William Wh. or Sm. V. 19 (P. P. IV. 7). Dead. Hands said to have one finger only present- 
Feet normal. 
Alfred, Wh. or Sm. V. 21 (P. P. unborn). At present in one of Dr Barnardo's homes. One 
finger only on each hand, the 4th, well developed. Feet. The outer digits alone present, though 
feet appear well developed save for the absence of the toes. 
We are indebted to Dr C. T. Ewart of Claybury Asylum for the facts and photograph of 
this case. 
For photograph : see Plate XXV, Fig. (vii). 
William Wh. V. 30 (P. P. IV. 15). Hands and feet deformed. 
Hands. Right and left are symmetrical. 
Carpus. Trapezium probably absent. 
Metacarpals. The inner three alone present- 
Digits. Little finger only present and has three phalanges with freely moveable 
joints. 
* This case is of peculiar interest as showing in the S.-farnily the occurrence of the same " bridge" 
type or " cross-bone " type that Lewis and Embleton have illustrated by skiagrams in the G. -family ; see 
Biometrika, Vol. vi. p. 41 and plates.
