we shall not only have circumnavigated the 
globe, but have done it in an orderly man- 
ner, and at the same time have kept near 
to the line of the physical development of 
the races. 
Naturally, when we come to select the 
groups and tribes to be represented there 
will be more difference of opinion, but the 
main point is to select such groups as are 
types, those which show decided variation 
from their neighbors, either in color, in 
stature, in hair, or in physiognomy. The 
limit to be put on the number of the groups 
will, of course, be determined very largely 
by the means at our command for this pur- 
pose, but certainly an exhibit which in- 
cludes less than sixty groups would be in- 
complete and more or less unworthy of the 
subject. 
There is next to be determined the exact 
character or nature of the material which 
is to be included in each group. This again 
must, to a large extent, be a matter of expe- 
diency or possibility. For some groups an 
abundance of material will be available; for 
others we must be content with a scant 
amount. But still it will be possible to 
keep in mind a standard below which it 
will be unwise to fall. There should be on 
the one side the group of casts, colored and 
dressed with the utmost accuracy and scien- 
tifie precision. From these figures can be 
studied the color, shape, size, hair, facial 
expression, relative length of limbs, shape 
of hands, feet, etc., as accurately as from 
the living subject. This should include at 
least three figures—the man, woman and 
child. By their side we may show the 
mounted skeletons, the scaffolding of the 
body. On the opposite side are series of 
skulls, shoulder-blades, pelves, long bones, 
etc., selected in such a manner as to present 
the typical osteological characters of the 
group we are representing. At the center 
and in the back are type photographs, an- 
thropometric charts, diagrams of sections

of hair, etc., and a map showing the exact 
geographical distribution of the group. 
Other maps or charts showing the physi- 
ography, fauna, flora and climate should 
be added whenever possible. Every ob- 
ject exhibited is to have its own individual 
label, and there is, of course, to be in the 
center a comprehensive label which sets 
forth in brief, concise language the chief 
characteristics of that particular group. 
In other words, as the first section il- 
lustrates the aims, objects and methods of 
physical anthropology, as the second section 
defines and exhibits the species man and 
sets forth his position in the animal world, 
so this, the third section, is an illustrated 
text-book of races and peoples, of ethnog- 
raphy. 
But we are not yet concluded with our 
scheme for an ideal museum, for so far pro- 
vision has only been made for the casual 
visitor and the thoughtful student; provi- 
sion must also be made for the investigator. 
A museum which fails to have its study 
series can never be considered complete. 
The museum can not, it does not, aim to 
supplant the universities, but it should aim 
to supplement them. It should clearly be 
borne in mind that the museum of to-day, 
if it is to be worthy the name, must be 
built up from the results of field exploration 
and investigation. No systematic or com- 
prehensive scheme for a scientific museum 
can be carried out from random gifts and 
occasional purchases. Accessions from 
such sources as these may in time grow into 
vast curio halls, but never into the scientific 
museum worthy the building which houses 
it, or the time of its care-takers. 
It is rare, indeed, that it is possible or de- 
sirable to place on permanent exhibition 
all the material which may be gathered 
from any single expedition. The duplicates, 
thus acquired, are too often regarded as en- 
cumbrances, fit only for purposes of ex- 
change, or, if that be impossible, they are
