IN TIMOR'LAUT. 353 



Notes ox the Table of Measukemexts. 



All the measurements given in tlio preceding tabic correspond to 



those recommended hy Broca in the ''Instructions Craniologiques " 



(Paris, 1875), except the following, some of "which are not given in that 

 work : — ■ 



The transverse arcs. — These arc measured with the tap3 from the point 



on the ridgo at the posterior root of tlio zygoma immediately above the 



middle of the external auditory meatus, where the ridge is crossed by 



the auriculo-bregmatic line (the cotirbe ans-avriculare of Broca) over the 



respective parts of the cranium, to the correspondicg point uu the 



opposite temporal bone. 



Nano'olveolar length. — From the nasion to the alveolar jRunt. 



Falatine regioiu — The maxillary length is measured from the alveolar 

 point to the middle of a line drawn across the hinder borders of tlie 

 maxillary tuberosities. This is easily done by stretching a i)]cce of fine 

 wire across the back of the mouth, the wire resting on each side in the 

 groove between the pterygoid and the tuberosity. The width is tak 

 between the outer borders of llie alveolar arch immediately above the 

 middle of the second molar tooth. 



Facial angle, — The angle formed by the meeting of the auriculo-alvco- 

 lar base line with the ophrj'o-alveolar face line at the alveolar point 

 measured with Broca*s median goniometer. 



Nad-malar angle, — The angle formed by the nasal liones and the ex- 

 ternal margins of the orbits at a point a little below the fronto-malaj 



articulation. 

 Nasi-maxillary angle. — Explained in the text, page 344. 

 Basilar angle.— Thi^ is the angle N B Y of the " Instructions," p. 92, 



or the naso-basio-opistliial angl3. 



Bi'zygostephanic Index. — Defined in the text, page 343. 



Conoroid height— From the gonion to the top of the coronoid process. 



Gonio-symphesial height measured with the calipers. 



The size of the glabella, nasal bones, and spine, inion, wormian bones, 

 and wear of teeth, are indicated by Broca's descriptive numl^ers given 



in the *' Instructions. 



Explanation of Plate (pp. 344, 345). 



All the figures represent the skulls with the alvcolo-condylar plane 



horizontal. 



The photozincograjjlis wore reduced from drawings by Mr J. G. 

 Goodchild, the outlines of the skulls from which they are taken having 

 been previously geometrically projected by means of Broca's stcreograi^h 

 by myself. ^ , , . ,
