x PREFACE TO VOL. XIX. 
“On Mvolution by Natural Selection,’ to which paper some 
remarks by Provessor VircHow on Evolution are appended. 
Mx. Hassell adds a second paper, entitled, ‘‘ Was Primeval 
Man a Savage?” in which the difficulties which beset the 
opinion that man was originally in that state are considered ; 
it is followed by an able review of the present state of the 
question of Hvolution and Development by the Rev. J. Wurre, 
M.A. The late Mr. W. P. Jamus, F.L.8., “ On the Relation of 
Fossil Botany to Theories of Evolution” ; this essay is followed 
by remarks from Sir Ricuarp Owen, K.C.B., F.R.S.; Mr. W. 
CarrutHers, F.R.S., F.L.8.; Dr. J. Braxron Hicks, I'.R.8., 
and others, which add to its high value. Lastly, Mr. D. Mackin- 
vos, F.G.8., gives a paper ‘On the recency of the Close of 
the Glacial Period in Nngland and Wales,’ which is followed 
by remarks by Proresson T. Rururr Jones, F.R.S., and others ; 
and a Note on the Falls of Niagara, with diagrams illustrating 
the important Report of the United States Government 
Survey thereof: all who remember how many arguments 
have been founded upon incorrect data as regards the rate of 
the recession of these Falls, will recognise the result of the 
surveys as being a distinct gain to geological science. 
To these, and to others who have added to the value of the 
present volume, the best thanks of the members and associates 
wre due. 
In conclusion, it may be permitted to recall the time when 
the Institute was founded, mainly because “ the idea that 
Science and Revelation were directly opposed to each other, 
was spreading with fearful rapidity,” and it was considered 
necessary “to investigate fully and fairly, but rigidly, all 
the facts and arguments put forth as truths newly discovered 
by Science, and regarded as being contradictory to the 
Scriptures.”’—(Youndation Address, 1865.) The volumes
