PREFACE 
NEBULA TO MAN is an attempt to present a sketch of the 
evolution of the Earth on the Nebular Hypothesis ; to note 
also subsequent sea and land movements, and successive appear- 
ances of life, as revealed by the geological strata. The 
geological record of past life remains very imperfect ; still 
many additions, notably from strata in Egypt and North 
America, have been made to it in recent years ; and, studied 
in the light of the doctrine of Evolution, its revelations 
have become much more intelligible. 
To attempt a work of this kind in rhyme is, I know, a 
bold experiment. But, however severely scientific in some of 
its aspects, the story of Geology is truly the most enchanting 
story in the world ; and rhyme may well be regarded as an 
appropriate form in which to present it. Indeed it is a fit 
theme for presentation in a much higher form than this ; and we 
may well hope that some day it will be taken in hand by 
some great poetic genius. 
My friend, the Rev. H. N. Hutchinson (author of Extinct 
Monsters, Creatures of Other Days, etc.) kindly read 'through 
my manuscript ; and I gained the benefit of his wide 
scientific knowledge, in many useful criticisms and suggestions. 
Mr Hutchinson also rendered me much assistance in 
working out restorations of extinct animals.
