ANTHROPOMETRY 91 



Preparation of Specimens. — Before a series of crania (or bones) 

 can be submitted to measurement or examination, the specimens must 

 be not only well cleaned, but also carefully repaired, which is interesting 

 work and at times calling for not a little ingenuity. For repair, about 

 the most suitable cement is a thick paste made from fish glue, or from 

 Page's liquid glue, with plaster-of-paris and pigment. A box of dry 

 sand in which to place the skulls or bones while the cement is setting 

 will also be required. 



I'he specimens, furthermore, must be numbered and catalogued, 

 otherwise there would inevitably be confusion. The method of 

 numbering is immaterial, so long as the numbers do not duplicate 

 others in the collection. The number, tribe, locality, and sex are 

 marked with indelible ink in the most convenient location, which in 

 the skull is perhaps the antero-inferior angle of the left parietal; and 

 all specimens of one kind in the collection are marked in the same 

 place. If the bone is scaly or too rough, a small parallelogram is 

 covered neatly with oil paint and the mark made on this. 



Sexing.^ — In adults, the determination of sex, from the skull alone, 

 while generally offering few difficulties to the well-trained observer, 

 is not equally easy in all racers, or in all individuals. 



A typical masculine skull differs in practically every feature from
