ANNOUNCEMENTS, 
We take pleasure in announcing the Manual of Zoology, by Prof. 
A. S. Packard, of Brown University. — At various times there have ap¬ 
peared from American authors, Text-books on Zoology, some of which 
have filled their places in the literature of science, while others have been 
noteworthy only from their errors and misstatements. Eaton’s “Zoolog¬ 
ical Text-book” (Albany, 1826,)was, we believe, the first American book 
embracing the whole animal kingdom ; since then, Ruschenberger, Agassiz 
and Gould, Hooker, Tenney, Morse, Orton and Steele have written text¬ 
books on this subject; and now appears this new work which seems to us 
a model in its way. 
Professor Packard’s work is intended for use in colleges, and is ad¬ 
mirably adapted for that purpose. It gives a clear, concise account of 
the Animal Kingdom, from Protozoa to Man, giving the anatomy and em¬ 
bryology of the various groups, and omitting (a feature which pleases us) 
much of the systematic work which has been a prominent feature in all 
other American books. It combines the advantages of laboratory work 
with that of the class-room, while, at the same time, it leaves nothing to 
be asked by the general student. The plan is briefly this : a detailed ac¬ 
count of the anatomy of some easily obtained form is given with illustra¬ 
tive figures, and this is made a type by which all allied forms are compared, 
and their resemblances and differences pointed out. The work, in every 
way, represents the present state of zoological science, and should be in 
the hands of every lover of nature. The author’s reputation as an authority 
on zoological subject is, we think, recommendation enough for the work. 
A New and Valuable Work on Archaeology.—We can furnish copies of the 
Memoir of the University of Tokio, Japan, “Shell Mounds of Omori,” 
by Prof. E. S. Morse. This book consists of 1 quarto vol. of 37 pages of 
text, and 18 double-paged plates containing over 300 figures of the pottery 
of that interesting country, printed by lithography, and very finely executed. 
Prof. Morse has just returned from Tokio, and lias written the work from 
his own observations. Persons interested in archaeology will find this 
book a valuable adjunct. The American Naturalist, after giving a synop¬ 
sis of the character and contents of the work, concludes by saying:— 
“In conclusion, we consider Prof. Morse’s Memoir one of the most impor¬ 
tant contributions to archaeology for the year 1879. 
Mr. John Robinson, author of “Ferns in their Homes and Ours,” has 
in manuscript, shortly to be published by the Essex Institute of Salem, 
Mass., quite an extensive paper entitled “The Flora of Essex Co., Mass.” 
It consists of an enumeration of the Flowering Plants, Ferns, Mosses, 
Lichens, Chara, Seaweeds, etc., growing in the vicinity, and those other
