Sorar ‘Puysics.* — Our geological readers will feel an interest 
in a work by one of the pioneers in the new series of researches — 
on the nature of the sun, which have tended to take astronomy 
out of the exact sciences and place it on a rank with its sister 
science, biology. The work is largely an essay on cosmical geol- 
ogy. In many ways it ‘commends itself to the geologist and biol- 
ogist, and is a fresh illustration of the close connection existing 
between the various branches of physical science. It is divided ee 
into two parts: I. A popular account of inquiries into the physical A 
constitution of the sun, with special reference to recent spectro- 
scopic researches ; and II. Communications to the Royal Society i 
of London, and the French Academy of Sciences, with notes. a 
The first part is naturally of more general interest, embracing a 
topics of which the following are some of the subjects: „Whati 
a Sun; The telescopic Appearance of the Sun; The Sun as a 
Type of the material Universe; The Place of life in a ‘Universe 
of Energy; The Atmosphere of the Sun, and several chapters on — 
the Eclipse. The style is clear and interesting, while the spirit of 
the writer is sanguine and bold, such as has marked the editorial — 
éonduct of “ Nature,” in which Journal some of these essays gee 
appeared. | 
Certainly the author has reason to thank his publishers for the 
sumptuous appearance of the volume, taking. rank as it does with 
the most beautiful works of a similar nature that have appe 
recently in England and'France. All devout astronomers’should, 
as becoming their profession, thank heaven for the appearance of : 
so fair and enticing a work, which will win its way to the warm 
. appreciation of many a non-astronomical reader. -
