line drawn across the hinder borders of the maxillary bones, 

 and its width between the outer borders of the alveolar arch 

 immediately above the middle of the second molar tooth. 

 The zygomatic projection is shown by the terms Phaeuo- 

 zygous (P.) and Cryptozygous (C), and was ascertained by 

 Sir William Turner's method. The breadth of the ramus is 

 its antero-posteria diameter on a line with the alveolar 

 border. 



The projections given were determined by Topinard's 

 craniophore, and the two angles arrived at by trigonometrical 

 calculation. 



We greatly regret that we have been compelled to omit 

 several angles and curves owing to our inability to procure 

 proper goniometers. However, we hope shortly to remedy 

 this. By the way, we found the craniometer figured in 

 Flowers' Osteological Catalogue very useful in measuring the 

 various diameters. 



In taking the important measurement of capacity, we have 

 used No. 8 chilled shot, and a funnel made according to Sir 

 William Turner's instructions. In fact, we here followed 

 closely Turner's method, excepting that as we could not 

 obtain the two litre measures, we were compelled to use the 

 one litre and half litre measures of Broca. This measurement 

 was taken separately by each of us, and again together in 

 each case.
