Cran ial Ti/pe- Con tours 
Illustrations of the type zone contours for the three sections of English 
crania of the 17th century are given in Diagrams III, IV, V reduced to half 
working scale*. 
(4) It is not the purpose of the present paper to reproduce type contours for 
the anthropoid apes and the different races of man, but rather to illustrate the 
possible value of the method in craniological studies. Accordingly special 
illustrations of the method have been selected in order to bring out its possi- 
bilities. The following series have been selected^. All represent male crania. 
I a, b, c, the three contours of the Cro-magnon skull. These are not type 
contours, but are individual contours reproduced for comparison (Figs. VI — VIII). 
II a, b, c. Congo. Skulls brought in 1864 from Fernand Vaz. Contours taken 
of 50 £ crania (Figs. IX— XI). 
III a, b, c. Congo. Skulls brought in 1880 from Fernand Vaz. Contours taken 
of 20 J crania (Figs. XII— XIV). 
These two series, II and III, were brought from the Gaboon by Du Chaillu, 
and are in the British Museum, Natural History. Both series have been fully 
measured by Dr Benington, and his measurements will shortly be published. 
IV a, b, c. Type contours of 41 £ Congo crania drawn by the kind permission of 
Professor Keith at the Royal College of Surgeons. They came from the Batetelu 
race (Figs. XV— XVII). 
V a, b, c. Type contours of 100 </ Egyptian crania. From Series E in the 
Biometric Laboratory, University College. This series of nearly 2000 crania was 
brought by Professor Flinders Petrie from excavations in a single cemetery south 
of the Gizeh pyramids, and belongs to the XXVI — XXX Dynasties (B.C. 600 
to 200) (Figs. XVIII — XX) j. The measurements are in progress and have not 
yet been published. 
VI a, b, c. Contours of 31 </ Eskimo crania at the Royal College of Surgeons 
(Figs XXI— XXIII). 
VII a, b, c. Contours of 14 </ Guanche crania at the Royal College of Surgeons 
(Figs. XXIV— XXVI). 
VIII a, b, c. Contours of 100 English crania from the collection of 17th 
century English skulls in the possession of Professor Thane at University College. 
Measurements on these series were published by Macdonell : see Biometrika, 
Vol. in, p. 191 (Figs. XXVII— XXIX). 
IX a, b, c. Living head contours of 106 Royal Engineers (Figs. XXX — XXXII). 
* The size of the scale is most important ; it is impossible to work from true scale drawings, they 
are far too small ; nor is it really feasible to work from photographic reproductions like the illus- 
trations to this paper, the photographer, however careful, never gets in all cases the exact size of the 
originals, and is liable to introduce sensible distortions. 
t Throughout (a) denotes the sagittal, (b) the transverse vertical, and (c) the horizontal contour.
