Views oF THE Microscopic Wortp.* — An American handbook 
of microscopy is too much wanted to be received in any other than 
a kindly spirit. Prof. Brocklesby’s “ Views of the Microscopie 
World,” Dr. King’s “ Microscopist’s Companion ” and Dr. Wythe’s 
“ Microscopist,” have been unavailable for years; and Dr. Rich- 
ardson’s recent work is interesting exclusively to medical readers. 
Yet any one who takes up the new book with a determination to 
be unreservedly pleased with it, cannot but be disappointed to find 
it only a new edition of one of the old ones, which ignores its pre 
decessor, and changes its name with the manifest intention of 
seeming like a new work. 
‘“* Views of the Microscopic World ” written by the same accom- 
plished author twenty years ago, was properly described, both by 
its name and in its preface, as no manual of microscopical vork, 
but as a common-place book of microscopic views, a collection of 
almost disconnected descriptions and illustrations, each valued for 
its own merits, of what were then unfamiliar microscopic objects. 
It was written in a thoughtful, philosophical and devout spirit. 
Fresh from the study of Ehrenberg and Mantell, and from the en 
thusiastic and successful use of a (then) remarkable microscope, 
the author briefly introduced and described the instrument, and 
then, evidently with a will, gave the longest chapter of the À 
full of interesting descriptions of the diverse organisms cl 
by Ehrenberg under the vague name of Infusoria. Next came 7 
teresting medley of information in regard to Fossil Infasori® 
Larger aquatic animals followed, up to insects, in a short chapter. 
Then came two chapters, the most valuable because the _ 
unique, with numerous lithographic illustrations of woot i 
and of artificial crystallizations. A final chapter reviews m 
parts of insects, and threw into the bargain mammals, w 
tiles and fishes— to say nothing of mollusks and vegetables. its 
volume, now little known, was pleasant and conversational or 
tone, the more so, perhaps, because informal, unclassified and me 
yond the reach of scientific criticism; and though published of
