III. ANGLES 



1. Spinal axis angle [AHD]; made by the intersection of the spinal 

 axis with the maximum length line. 



2. Infra-spinous angle [ABD]; made by the intersection of the infra- 

 spinous line (prolonged) and the spinal axis. 



3. Vertebral border angle [ABG]; the angle between a line drawn tan- 

 gent to the vertebral border and the spinal axis. 



4. Axillo-spinal angle [BKD]; the angle made by the line of the axil- 

 lary border length and the line of maximum breadth, meeting at the 

 point [K] in the diagram. 



The measurement of all of these angles can be best effected by the use 

 of knitting needles, fastened directly upon the bone by wax or plastillna, 

 and thus defining the lines. The angles are read off by a transparent 

 protractor. 



IV. TABLE OP SCAPULAR MEASUREMENTS* 



* The above results are those of various authors, as found in MOLLISON (1908) and 

 MARTIN (1914. pp. 977-978). The Europeans were studied by FLOWER and GARSON 

 (1880), the French by LrvoN (1879), and the Australians by TURNER (1886,. As 

 elsewhere, the numbers of individuals studied in each case are given in parenthesis 

 following the name of the race.
