evolution of dramatis persone rising out of the limitless spaces, passing 
across the astronomical stage and descending again into the depths 
whence they rose, Itis a work of immense learning.—New York Home 
Journal. 
The systematic and very comprehensive way in which the author has 
treated most of the important questions of the day that concern equally 
the sciences of astronomy, geology and physics, makes the work a most 
timely one, and the candor, research and independent thought which 
have been given to this task are points of excellence that the scientist as 
1. 
well as the popular reader will appreciate. * * * * A perusal of 
the book has led the writer to think that it is one of the most important 
contributions to science that has appeared in America, at least for years. 
—The Sidereal Messenger. 
We know of no other work in which the reader can find a full, con- 
nected and systematic presentation of the results of cosmical research 
that will compare with this.—Popular Setence Monthy, Feb., 1884. 
1884. In rapid succession appeared ‘Geological Excursions, ”’ 
a rudimentary book for young learners in geology, and ‘‘Geolog- 
ical Studies,”’ a text-book of higher grade, both published by 8. 
C. Griggs & Co., of Chicago. The immediate instigation to the 
preparation of the former was a request for such a work from a 
Boston publisher. It appeared in May, 1884. It is ona plan 
entirely new among text-books of geology. The etfort was made 
to do for geology what has been done especially for botany, in 
directing the learner's attention to the characters of some of the 
most familiar objects, instead of putting before him an array of 
abstract definitions, theories and classifications which cannot be 
appreciated by those faculties in easiest and most active exercise 
in the child. 
He contributed an article to the //lour/letic Monthly CN, Ye 
March, which appeared in a ‘*Symposium” on the question: ‘Is 
the Darwinian theory of evolution reconcilable with the Bible?” 
Other writers in this symposium are Rey, Drs. Patton and MeCosh 
of Princeton, and Dr. Gulliver, of Andover, THe contributed 
matter amounting to 45,000 words to ‘‘Johnson’s Animal King- 
dom Illustrated,” mainly on zoological topics, and distributed 
through 22 different articles. This was published in the early 
part of 1885. 
1885. In the Supplement to ‘*‘MeClintock and Strong’s Cyclo- 
pedia” appeared his article on Evolution. This is a general ex-

speculations, theories and literature, consisting of 9,000 words
