ls it, is one of surpassing
interest. His treatment is a marvel of clearness and comprehensiveness;
discarding non-essential details, he selects with a fine historic
instinct the main currents of history, traces them with the utmost
precision, and tells the whole story in a masterly fashion. His little
volume will be a text-book for older quite as much as for young
readers.--_Christian Union_ (New York).

"You must allow me to thank you for the very great interest with which I
have at last slowly read the whole of your work.... I never in my life
read so lucid an expositor (and therefore thinker) as you are; and I

his acceptance of the utmost logical results of recent scientific
discovery is Mr. Fiske's assurance that the foundations of spiritual
truths, so called, cannot possibly be shaken thereby.--_The Atlantic

To each study the writer seems to have brought, besides an excellent
quality of discriminating judgment, full and fresh special knowledge,
that enables him to supply much information on the subject, whatever it
may be, that is not to be found in the volume he is noticing. To the
knowledge, analytical power, and faculty of clear statement, that appear
in all these papers, Mr. Fiske adds a jus
