and by no means as probable as the author 
maintains. The oceans of boiling water remind 
one of the cataclysmal hypotheses in vogue in 
earlier geological speculation, and raise the 
question whether here also there may not be a 
less sensational interpretation of facts. 
The lunar temperature, on the other hand, 
in regard to which we have some knowledge 
derived from quantitative measurements, is not 
so much as mentioned in the book. 
Barnard’s fifth satellite of Jupiter is given a 
whole page, which, while commendable as an 
account of recent astronomical progress, seems 
to show a‘lack of perspective, since only an 
equal space is‘devoted to the other four moons 
with their wonderful harmony. Moreover, in 
spite of the prominence given to this excessively 
minute body, the moon, which continues to be 
called by an anachronism by the Roman nu- 
meral I, is alluded to as ‘ the innermost.’ 
The ‘invisible rays’ of the solar spectrum 
are treated as if they were synonymous with 
the ultra-violet rays. Over a page is given to 
this topic, but there is no mention anywhere 
of the much more extensive infra-red part of 
the spectrum which comprises rays of greater 
intensity and of more importance to the earth. 
The statement on page 39 that ‘we find each 
one of the multitude of lines in the artificial iron 
spectrum agreeing to the last degree of precision 
with the corresponding line in the solar spec- 
trum,’is not in accordance with facts. Along 
with many wonderful coincidences, there are 
some notable differences which are of very great 
importance as furnishing a possible key to 
further solar mysteries. 
The description of the solar corona and of 
sun-spots in Chapter II. is inadequate, and some- 
thing more than a bare mention of the fact that 
there are different classes of stellar spectra is 
desirable ; but the list of shortcomings is not 
long, and the book is to be commended for its 
attainment of an exceptional standard of ex- 
cellence.
