That the eye is not always to be trusted will be readily 

 admitted by anyone accustomed to making comparisons 

 between objects differing only slightly from each other in 

 form. Even if the objects possess very considerable unlike- 

 ness, but have a complicated outline, mere inspection may

 to its length, than that of the pig ; whereas actual measure- 

 ments prove the converse to be the case. Anthropologists 

 long ago recognised the necessity for a system of cranio- 

 metry, by means of which they might be enabled to appre- 

 ciate accurately the differences in the skulls of men of 

 diverse races, or of men of the same race. And it has been 

 also felt by morphologists, working with other mammalian
