What is now observed in man ? We refer in the first place to 

 figs. 12 and 13. In 12 a horizontal section is given through 

 the orbits of a new-born infant, in 13 through tlie orbits of an adult

 we wish to answer the question whether the orbits are also in man

 extent this happens, we have only to compare the position of the 

 orbits in both figures with regard to this line. It then appears that 

 thei'e is no evidence of such a shifting. For in the infantile as well
