ng nose (5.5 cm.) The
man (No. 2) whose nasal index is 100 has the mesaticephalic cranial
index of 78.3 (almost the average index). The other man (No. 4)
whose nasal index is 100 has a head of exactly the average length
(18.5 cm.) and the greatest breadth (15.4 cm.), and the brachycephalic
cranial index of 81.2. The man (No. 17) with the lowest nasal index
of 71.4 has a very short head (17.7 cm.), and the brachycephalic
cranial index of 82.2.

The following tables, however, illustrate the fact that the
measurements of these twenty men do not appear to indicate, as
regards them, any marked connection between stature, cranial index,
and nasal index.

Order in stature (beginning with the shortest):

20--1--19--6--7--17--5--15--18--2--3--11--16--4--12--13--14--9--8--10.

Order in progress upwards of cranial indices:

8--13--3--6-20--5--ll--7--1--16--18--2--14--9--15--4--12--17--19--10.

Order in progress upwards of nasal indices:

17--9--6--8--15--19--3--13--7--16--20--11--10--14--18--12--1--5--2--4.

I brought home three Mafulu skulls, which Dr. Keith kindly had measured
at the Royal College of Surgeons, with the following results [28]:--

Skull
| Length in cm.
| | Breadth in cm.
| | | Height in cm.
| | | | Cranial Index.
| | | | | Proportion of
| | | | | height to length.

A 17.6 14.0 12.2 79.5 69.3
B 18.2 14.1 13.2 77.5 72.5
C 17.3 12.7 12.5 73.4 72.3

It will be observed that the lowest of these three cranial indices is
a trifle higher than the lowest of those of the head measurements,
that the highest of them is much lower than the highest of those
of the head measurements, and that their average (76.8) is a little
below the average of those of the head measurements.

Dr. Keith had further measurements made of these skulls from the
point of view of prognathism and characters of noses and orbits,
with the following results:

Skull.
| Basi-nasal length.
| | Basi-alveolar length.
| | | Height of nose.
| | | | Width of nose.
| | | | | Height of orbit.
| | | | | | Width of orbit.
