CHAPTER XXI. 



MAN AND THE GLACIAL PERIOD. 



When, in 1863, Sir Charles Lyell published his great 

 work upon " The Antiquity of Man," the general public was 

 somewhat surprised to find that one hundred and sixty pages, 

 or almost one third of the entire volume, was devoted to a 

 discussion of glacial phenomena. This course was justified 

 by the fact that rough-stone implements, undoubtedly of 

 human manufacture, had recently been found in deposits 



supposed to be of 

 glacial age in north- 

 ern France and 

 southern England, 

 making the question 

 of the antiquity of 

 man one no longer 

 of mere history or 

 archaeology, but of 

 glacial geology. A 

 further reason for 

 the prominence giv- 

 en to the discussion 

 of purely glacial 

 questions in Sir 

 Charles Ly ell's work 

 was the comparative 

 ignorance, at that 

 time, of the character, extent, and significance of glacial phe- 

 nomena. The discussions running through the previous

 The large one in the middle row is from Amiens, 

 France. The two at the left of it are from France. 

 The one at the right is from up:>er Egypt. These
