10 ANNIVERSARY ADDRESS. 
have been such as to break the continuity of mammalian life, and 
so to destroy Darwin’s theory. He himself admits, in the “ Origin 
of Species,” 6th edition, page 330, that there is evidence of every 
conceivable kind, organic and inorganic, “ that within a very 
recent geological period Central Europe suffered under an arctic 
climate ; and the ruins of a house burnt by fire do not tell their 
tale more plainly than do the mountains of Scotland and Wales 
tell their tale of glaciation.” And in the latest edition of the 
“Origin of Species” he says (pp. 448-50): “T had hoped to find 
evidence that the tropics, in some parts of the world, had escaped 
the chilling effects of the glacial period, and had afforded a safe 
refuge for the suffering tropical productions ; but all the geological 
evidence we possess relating to that period points to conditions 
that would render almost inevitable a break in the continuity of 
mammalian life.” 
Dr. Page, in his “Text Book of Geology,” referring to Britain 
and the North of Europe, says that “the large mammalia of the 
earlier tertiaries disappeared, and the land was submerged to the 
extent of several thousand feet. Sir Henry de la Beche, Sir 
Roderick Murchison, and Sir Charles Lyell all agree in the 
evidences of this glacial epoch, extending over the whole of the 
eastern hemisphere. Sir Charles Lyell says, in his “ Principles of 
Geology,” 11th edition, p. 253, that “in one part of the glacial 
period the desert of Sahara was under water between latitude 30 
and 20 (a breadth of nearly 700 miles), so that the eastern part of 
the Mediterranean communicated with that part of the ocean now 
bounded by the west coast of Africa.” Any retreat of the 
mammalia southward on the African continent would thus have 
been effectually cut off 
Tt has been confidently asserted that man had no existence in 
pre-glacial times, and that every attempt to prove otherwise has 
signally failed, Now, if before the glacial epoch man was not, but 
when it passed away man was there, when did the evolution take 
place? This is the question that has failed t ive a satisfactory 
solution. Everything seems to turn upon this one point—that is
