of loose morals and of a peculiar temperament, which is recorded 
from the similarity to Dr. JoLLy’s case. Figure 1 represents a cast 
taken after death which also is in the Museum of the Harvard Medical 
School. It shows a left forearm and a very broad hand having four 
normal fingers and, in place of the thumb, the three inner fingers of 
a right hand which were smaller than 
the others. The hand is flexed and 
somewhat pronated, so that this figure 
shows the back of the elbow and the 
palm of the hand. The dissected 
specimen is in much the same posi- 
tion but less strongly flexed. The 
carpus and metacarpus are arched 
transversely so as to form a deep 
hollow in the hand. Dr. JACKSON 
said in his report of the case to 
the Boston Society for Medical Im- 
provement in the summer of 1852: 
„the hand was not merely very useful 
to him in the way of his business, 
but gave him some advantages, he 
thought, in playing upon the piano, 
upon which instrument he was a 
performer. The three upper fingers, 
supposing the hand to be laid in 
a state of semipronation, were used 
efficiently as a thumb to oppose 
the three!) others. Various obser- 
vations were made upon the mo- 
tions of the hand and fingers.“ Un- 
fortunately these were not recorded in the hospital records and no 
notes bearing on them can be found among Dr. Jackson’s papers. 
The left arm was shorter than the right. Dr. Jackson gives the 
length of the left forearm as 8'/, inches and that of the humerus as 
10 inches, the right ulna measuring nearly 10 inches and the humerus 
13 inches. The scapula is very peculiar. The supra-scapular notch 
1) Dr. Jackson says „three“ instead of „four“ as he looked on the 
normal index as a central finger with three on either side of it — a view | 
to which I cannot agree, though it has some support in the plan of the 
extensor tendons.
