chap, xiii.] COMPLEX POLYDACTYLISM : MAN. 339 



regarded as the medius, there were two complete digits (3, 2) each 

 having three phalanges : and on the radial side of the innermost of 

 these digits there was a stump-like rudiment (1), apparently representing 

 another digit. [This case therefore differed from those of Win die and 

 Rijkebiisch in the fact that both the digits internal to the medius (m) 

 were disposed as though they belonged to a left hand, and Kuhnt, in 

 fact, states that each hand was, as it were, composed of parts of a pair 

 of hands, thus agreeing with Jolly's case, No. 499.] 



Left hand. In this hand there were only five digits, each of which 

 had three phalanges. None of them was fully opposable, but that on 

 the radial side (1) could to some extent be moved as a thumb. Of 

 these five digits the middle one was the longest, and on each side of it 

 there were two similar digits, those next to the middle finger being the 

 longest and those remote from it being a good deal shorter and having 

 the form of little fingers, which Kuhnt considers them to have been. 

 [This hand is perhaps in Condition II.] 



Right foot. The hallux (2, 3) was of abnormal width and its bones 

 were to some extent double, the ungual phalanx being completely so. 

 [The nail however is drawn as a single structure and the double character 

 of the toe was not apparent in its external appearance.] On the internal 

 (tibial) side of the hallux there were two supernumerary toes (1, 1) 

 having, so far as could be ascertained, a single metatarsus. The 

 number of phalanges in these toes is not distinctly stated. 



Left foot. The hallux (3, 4) was to some extent double, like that of 

 the right foot. Internally to it were two supernumerary toes (1, 2) 

 having apparently a common metatarsal. [Of these the most internal 

 is represented as being very wide and resembling a hallux, but this 

 feature is not mentioned in the description and the number of phalanges 

 is not given]. 



[It is greatly to be regretted that no fuller account of this important 

 case is accessible. According to Kuhnt's view each hand and each foot 

 were structurally composed of parts of a complementary pair of hands 

 and feet. As regards the hands the facts agree witli this description 

 and with what has been seen in other cases, but the condition of tin 1 

 feet is more doubtful, and without more knowledge of the details no 

 opinion can be given. It should be remembered that the original 

 description is very brief and Dr Kuhnt offers an apology for the im- 

 perfection of the figures.] Kuhnt, Virch. Arch, f path. Anat. u. Phy8.,

 case (No. 501). Ekstein, Prager Wochens., No. 51, 1891. 



502. Man whose right arm beside the normal hand bore an extra thumb 

 and finger. The two thumbs were united and had a common meta- 

 carpal joint. They were of equal size. They were flexed and extended 

 together and had the power of spreading apart. The extra finger was 

 beyond the extra thumb and was shaped like an index. Besides the 

 radius and ulna of the normal arm there was an extra radius on the 

 outer [1 internal] side of the normal radius. This bone had a joint of 

 its own at its elbow. The wrist was broad, suggesting the presence or' 

 additional bones. Nothing is said of a metacarpal bone for the new 

 index. Carre, Seance publ. de la soc. rog. <1> Mid., Ghir. et Pharm. de
