1. KuEFF. De Conceptii. Frankfurt, 1587, Plate 41. In the text it is stated that 

 there are twelve fingers but, according to Morand and to Tarnffi, the plate shows a child 

 having two hands joined hy the idnai- side, each with five fingers. There were also 

 double feet.

 side. 



3. Kerkrixg. (Jhscrcat. Aunt. Amsterdam. 1670, p. lo, (Jbs. XX, with plate. 

 A skeleton of a boy with seven fingers on each hand of which the longest were in the 

 middle. On the right there were seven metacarpals but a thumb could not be recognized. 

 On the left hand there were apparently five metacarpal Ijones. The first phalanx of 

 the thumb arose on the outside of the 7th finger. One foot had eight toes and the 

 other nine. [This is on the authority of Tarufiti. It seems the least certain of these 

 cases.] 



4. Dii CouRAi. Journal des Savants. 1696. An infant with eight fingers on the 

 right hand, of which the two indices were joined together as well as the two little fingers. 

 [It is not easy to see how this could occur unless the hands were put face to face.] There 

 were seven fingers on the left hand of which the indices were joined and the rest separate. 

 It seems from the context that there were no thumbs. Both hands were bent inwards 

 on the wrists and could not be extended. The metacarpus was a third longer than usual. 

 Each foot had seven toes, of which the great toes of each foot were united. The head 

 was monstrous.

7. Murray. Medlco-Chirunjical Trans. Vol. XL VI, London, 18Go. This is a very 

 noteworthy case especially in coimection with the one which is the sultject of this paper. 

 A woman, thirty-eight years oM, living at Brighton, had two hands of four fingers each 

 on the left arm, united at the radial side. '-The fingers of l)oth hands are clubbed at 

 their tips. The middle and ring fingers of the .supernumerary hand are webbed as far as 

 their proximal joints and the movements of the fingers of this hand are somewhat stiff 

 and imperfect. The thumbs .seem to be represented only by the prominence on the dor- 

 sal surface seen in figure ?>." This is a very poorly shown little projection apparently on 

 the back of the proximal phalanx of the index of the normal hand. [It may be advis- 

 able to point out that when, as in this case, we have two hands united by corresponding 

 sides, one of them must be a right hand and the other a left hand. The one which is of
