In this abstract I mention only the more modern and important 
cases. They are more fully discussed in my original paper. 
1) Murray, Medico-Chirurgical Trans, Vol. XLVI, London 1863. 
This is a very noteworthy case especially in connection with the one 
which is the subject of this paper. A woman, thirty-eight years old, 
living at Brighton, had two hands of four fingers each on the left arm, 
united at the radial side. 
2) Grratpbs, Maladies chirurgicales des enfants. A case of a child’s 
hand with eight fingers in two sets and no thumb’). A clear case of 
two nearly perfect hands fused at the radial sides. GIRALDkS refers to 
two similar specimens which, having injected and dissected, he placed in 
the Musée de l’amphitheätre des höpitaux. Of these Fort?) says in 1869: 
„Nous ne les avons pas trouvées.“ 
3) Grratpis, Bull. Soe. Chirurg., Nov. 1865. M. Gimatpés said: „I have 
had an opportunity to see in my service a case of two entire hands on 
a single forearm. M. Gurrsant has seen the same person.“ 
4) Fumacatui, Sulle deformitä congenita della ditta. Annali Univ. di 
Med. Milano, Vol. CCXVI, p. 305, 1871. A girl of four months without 
family predisposition had the right hand with eight fingers and no thumb. 
The two sets were united by the radial side. The double hand was 
anchylosed at a right angle to the forearm. The extra fingers had less 
motion than the normal ones. Their metacarpal bones were incomplete. 
5) Kuant, Virchow’s Archiv, Bd. LVI, 1872. A German recruit 
twenty-one years old. Each hand consists of the ulnar half of two hands 
fused. The left hand consists of five fingers and no thumb. Three of 
the fingers apparently are of the left hand to which are added the ring 
and little fingers of a right hand. The right hand is less symmetrical. 
There are the three normal fingers of the ulnar side to which are added 
two fingers and a rudiment of a third of a left hand. 
6) Grreuini, Gazetta Med. Ital.- Lombardo, No. 51, 1874. A boy 
five years old had six fingers on each hand divided into two groups. It 
is a clear case of the fusion of the ulnar sides of two hands. 
7) F. Jotty, Festschrift, RupoLr Vırcmow gewidmet, Bd. I, Berlin 
1891. This case is the most important one. 
8) Carré, Séance publique de la Société royale de Médecine, Chi- 
rurgie et Pharmacie de Toulouse, 1838, pp. 28—30. This case differs 
from the others; for there is one complete hand and a part of another 
fused with it. A goldsmith had on his right arm, beside the normal 
hand, an extra thumb and index finger. The latter thumb was next to 
the normal one and the index further from it showing that of course 
they belonged to a left hand. Indeed the two thumbs were united and 
1) This is the case erroneously attributed to Lanceraux, in: ZIEGLER'S 
Lehrbuch der pathologischen Anatomie, 1892.

1869.
