Horizontal Circumference. — We find the average horizontal 

 circumference of six males and five females to be 502. J. B. 

 Davis, in 10 skulls, finds an average of 507. Topinard, 

 taking the averages of the two sexes combined, as in the 

 other instances quoted, one of 514. In the Cambridge col- 

 lection, two skulls give an average of 500. Combined, these 

 figures give an average horizontal circumference of 506mm. 



Bizygomatic Diameter. — The diameter, which shows the 

 maximum breadth of the face, averages 129mm. in the five 

 skulls which we were able to measure. In 10 skulls, J. B. 

 Davis finds an average of 130. Topinard, one of 127. In 

 one skull in the Cambridge collection this diameter measured 

 124mm. These figures combined give an average bizygomatic 

 diameter of 127mm. 



In conclusion, we wish to express our thanks to the Fellows 

 of the Society and to the other gentlemen who have given us 

 assistance in various ways. First of all to the Museum 

 authorities for their courtesy in allowing us the use of their 

 room in the evenings. To Mr. J. B. Walker for the loan of 

 books and papers. To Mr. Russell Young and Mr. Arthur 

 Butler for the excellent photographs which accompany this 

 paper. To Mr. Ward and others for the loan of measuring 

 glasses, instruments, shot, etc. Lastly, Mr. Chairman, ladies, 

 and gentlemen, we thank you for your kind attention to a 

 paper which, in order to be scientifically accurate, must 

 necessarily be somewhat tedious to any but an enthusiastic 

 anthropologist.
