"Professor Young is an authority on 'The Sun,' and writes from
intimate knowledge. He has studied that great luminary all his
life, invented and improved instruments for observing it, gone
to all quarters of the world in search of the best places and
opportunities to watch it, and has contributed important
discoveries that have extended our knowledge of it."--_Popular
Science Monthly._
Spectrum Analysis, in its Application to Terrestrial Substances,
and the Physical Constitution of the Heavenly Bodies. Familiarly
explained by Dr. H. SCHELLEN, Director der Realschule I. O. Cologne.
Translated from the second enlarged and revised German edition by
JANE and CAROLINE LASSELL. Edited, with Notes, by WILLIAM HUGGINS,
LL. D. With numerous Woodcuts, Colored Plates, and Portraits; also,
Angstroem's and Kirchhoff's Maps. 8vo. Cloth, $6.00.
"This admirable work does credit to, or should we say is worthy of,
the author, the translators, and the editor. The first part treats
on the artificial sources of high degrees of heat and light; the
second on Spectrum Analysis in its application to the heavenly
bodies. We must approve the method followed in the translation and
by the editor. In many translations the views of the author are
suppressed, in order that the views of the translator or editor may
be expounded; but here Dr. Huggins, however leniently such a fault
might have been looked upon with him, has permitted the author's
views to remain intact, clearly stating his own and wherein lies
the difference."--_The Chemical News._
"Certainly, as regards mere knowledge, the 'Spectrum Analysis' has
let us into many secrets of the physical universe which Newton and
Laplace would have declared impossible for man's intellect to
attain. The science is still in its infancy, but it is prosecuted
by some of the ablest, most patient, and most enthusiastic
observers, and some of the keenest thinkers, at present existing
on our little, insignificant physical globe."--_Boston Globe._
Studies in Spectrum Analysis. By J. NORMAN LOCKYER, F. R. S.,
Correspondent of the Institute of France, etc. With Sixty
Illustrations. 12mo. Cloth, $2.50.
"The study of spectrum analysis is one fraught with a peculiar
fascination, and some of the author's experiments are exceedingly
picturesque in their results. They are so lucidly described, too,
that the reader keeps on, from page to page, never flagging in
interest in the matter before him, nor putting down the book until
the last page is reached."--_New York Evening Express._

"'The Expanse of Heaven' can not fail to be of immense use in
forwarding the work of education, even when it is read only for
amusement, so forcible is the impression it makes on the mind from
the importance of the subjects treated of, while the manner of
treatment is so good."--_Boston Traveller._

Inhabitants, considered as illustrative of Geology. By Sir CHARLES
LYELL, Bart. Illustrated with Maps, Plates, and Woodcuts. A new and
entirely revised edition. 2 vols. Royal 8vo. Cloth, $8.00.

of experience and observation in every region of the world, the work
has incorporated with itself each established discovery, and has
been modified by every hypothesis of value which has been brought
to bear upon, or been evolved from, the most recent body of facts.
