He loves ; the “ New Jerusalem ” with its “ walls and gates ; 
the “ nations cf the saved ” ; “ the kings of the earth bringing 
homage and offerings thither”; the “ Tree of Life in the

APPENDIX TO AN EXAMINATION OF TEE BOOK 
ENTITLED “ THE UNSEEN UNIVERSE .” 
55. Professor Clifford ( Fortnightly Review, June 1, 1875) 
concedes, that the writers of The Unseen Universe, with 
whom he severely remonstrates, “speak from the 
ciiftord’s°cri- standpoint of a wide and accurate knowledge of 
tidsms. physical science, accurately and clearly expounded, 
as far as it was wanted” (p. 777), but he proceeds both jocosely 
and seriously to criticise them and their science. He says : 
“ The Unseen Universe, which they defend, lies within the 
limits of those physical doctrines of continuity and conserva- 
tion of energy which are regarded as the established truths of 
science.” It is something which is to the luminiferous ether, 
what the luminiferous ether is to molecules. “ It is of finer 
structure, and receives the energy which the ether loses by 
friction”— (just as the luminiferous ether receives the energy 
which the molecules lose). 
As we notice the course of Professor Clifford’s scientific 
objections to this work and its authors, we at once learn, per- 
haps, something as to the value of the religious inferences from 
the premisses when estimated by a physical science critic. 
56. We linger not on the Professor’s preliminary objection 
to the interpretation given in this book of the Im- 
mortality desired by man. If, as he supposes, it 
would satisfy all the historical facts of our immortal 
longings to say that man simply “shrinks from 
His mini- 
mizing the 
desire of im- 
mortality is an 
oversight.
