No. 397.] COLLECTIONS OF HUMAN BONES. I5 
The arrangement of specimens for exhibition differs much 
from that for storage. It should be based on at least two 
principles, namely: The normal bones should be arranged in 
series showing all their variations, the pathological and anoma- 
lous bones in series showing as many grades or steps as pos- 
sible in the evolution of their specific characters. The series 
are arranged according to the order in which the bones of the 
human body are generally treated in anatomical works or lec- 
tures. . Wherever possible, the series should be supplemented 
by casts or pictures and by specimens from lower mammals, fit 
for comparison. Explanatory labels with references, and, if 
possible, with a special card catalogue for the museum, com- 
plete the value of the exhibitions.
