to be the cuneiform bone. There is but one bone to represent radius and 

 ulnar and that is united to the humerus without any elbow joint, and 

 there is a long, extended internal condyle to the humerus. 



On the right arm the same arrangement for humerus, radius and 

 ulnar is present, but the one bone representing radius and ulnar is some- 

 what longer than the left. There is a rudimentary scaphoid, a trapezoid, 



05 magnum and unciform and a cuneiform, but the other carpal bones 

 are absent. There are three metacarpal bones, to the one is attached a 

 double phalanx made by the union of the proximal phalanx of thumb 

 and index finger, and then there are thumb, index, middle and ring 

 fingers but no little finger and no metacarpal bone of the thumb. In this 

 case the greater deformity is on the left side. 



Here is a similar deformity in a man of 55 years of age. On the 

 left side he has both radius and ulna with an apparent tendency to 

 fusion of humerus and ulna with lengthening of the internal condyle of 

 humerus. At the wrist joint, there is a scaphoid bone and rudimentary 

 trapezium, there is apparently an os magnum and unciform, the other 

 bones of carpus rudimentary, three metacarpal bones for fore finger, 

 middle and ring finger, none for thumb or little finger and the same 

 arrangement as in the boy's fingers of light hand. In the man's right 

 hand the radius and ulna are nearly perfect. There is a scaphoid, semi- 

 lunar and cuneiform blended, a pisiform but no trapezium, there is a 

 trapezoid os magnum and unciform, there is present a complete index, 

 middle and ring finger with a rudimentaiy thumb, and the metacarpal 

 bone of the little finger blended with the metacarpal bone of the ring 

 finger. 



The next is a club-foot on the left side and not on the right. 



The next (No. 9) is a deformity of the left leg, the tibia and fibula 

 end in expanded bony growths, and the bones of the foot are represented 

 by rudimentary points of ossification, and here is a case (No. 10) of 

 congenital absence of the left fibula. 



Here is a picture of another abnormal left arm recorded by Dr. 

 Jubb,^ Glasgoi7 Eoyal Infirmary. In this case the deformity is absence 

 of radius in its greater extent and of the carpal and metacarpal bones 

 of the thumb. This deformity is again on the left side.
