PART VI. {Conclusion) 



Chronology : Recent Discoveries 



We now approach the last and most difficult portion of our 

 task, and must endeavour to assign the stages of human industry 

 we have already discussed to their appropriate places in some 

 scale of time, such as that to which we were led by our studies 

 of the glacial epoch. 



But, as if this problem were not complicated enough in 

 itself, it involves another not less so, for the scale we have 

 adopted is by no means universally accepted by those who 

 have given most attention to the subject. Some there are, like 

 Mr. Lamplugh among English geologists, and Prof. Geinitz in 

 Germany, who, adopting the views of the late Prof. Carvell 

 Lewis, recognise only a single undivided glacial epoch, and 

 reject in the most uncompromising fashion all notion of inter- 

 vening genial episodes. It would be impossible to enter here 

 into the elaborate arguments which have been adduced on both 

 sides in this thorny controversy, but on a review of the facts it 

 does not appear that any evidence has yet been adduced suffi- 

 ciently cogent to invalidate the conclusions set forth in our first 

 article. In the camp of the " Interglacialists " themselves, 

 however, differences of opinion are not wanting ; thus Prof. 

 James Geikie, who is not content with less than six glacial 

 ages, has a numerous following, especially in America, where 

 it is even said that as many as seven of these ages can be 

 recognised ; on the other hand, Prof. Marcellin Boule and the
