inces and formed the Triassic Arctogaeal 

 province. Then followed a depression during 

 the Triassic period with a checking of further 

 development there, and a consequent progres- 

 sive modification and development elsewhere. 

 In the latter Mesozoic there was an upheaval 

 around the shores of the Atlantic, and a move- 

 ment of vertebrate Fauna westward increasing 

 in extent up to and in some directions even 

 after the Miocene epoch. 



It is difficult to estimate the value of these, 

 but relatively the second is worthy of the 

 greater consideration and is borne out, in some 

 particulars at least, by facts derived from vari- 

 ous sources. A great deal of stress has been 

 placed upon the synchronism of geological strata, 

 but as Huxley well remarks, "All that geology 

 can prove is that local order of succession, 

 homotaxis (similarity of arrangement) and 

 synchronism (identity of date) with regard to 

 geological strata are not contemporaneous and 

 prove nothing. The hypothesis of evolution 

 explains the facts of Miocene, Pliocene, and 

 recent distribution, and no other supposition 

 even pretends to account for them."

There is no longer any doubt as to the posi- 

 tion man now occupies in the order of created 

 things. Even the most radical unbelievers are
