and grown individuals, separated into males and females. In 
large series the embryos, adolescents, and very old may be 
advantageously separated from the others. The best way to 
preserve these collections is in tiers of sliding shelves or 
drawers. The anthropological collection as a whole is arranged 
on the basis of race and type, and further subdivided according 
to the geographical distribution. A zoólogical collection is natu- 
rally best arranged on the basis of the grade of evolution of 
the animals. This rule may be followed from the most com- 
prehensive zoólogical subdivision to individuals. 
The method of arrangement in large collections of human 
bones of a comparatively homogeneous character, such as the 
bones of whites, when the object of these collections is to be 
a possibility of a thorough investigation on the bones, must 
differ from the above. 
Anatomy is past the stage of study of single normal bones, 
just as it is past the stage of study of any single normal organ 
in the body. The present and future anatomical investigations 
can only deal with large numbers of specimens. The points 
which are to be settled by the investigations concern, in the 
first place, the regular changes or life history of each indi- 
vidual bone. We are further to learn the prevalent types of 
each bone and their meaning; to complete our knowledge 
of the more primitive, recurrent, and anomalous, and define 
the prospective characters of each bone; and to establish the 
influences on the various bones of recent as well as hereditary, 
normal, and abnormal characters. 
In order that such studies may be possible, all the bones in 
our collections must, in the first place, be identified; in the 
second place, they must be supplemented with certain data on 
the subjects from which they proceed ; and in the third place, the 
bones must be so stored as to present the utmost facility for any 
study desired. 
So far no osteological collection of hick I i any knowl- 
edge comes fully up to the stated requirements ; the collection 
that comes nearest to the desired standard is in all probability 
that of Prof. Geo. S. Huntington, in the College of Physicians 
and Surgeons, New York City. However, as the value and
