FIELD.—"The book can be in the strongest manner recommended to those for whose benefit it has been written. We know of no work from which a more truly scientific account of the Protozoa, Echinodermata, and other lower forms of animal life could be gained."
VOLUME II.
Flatworms and Mesozoa, by F. W. Gamble, D.Sc.; Nemertines, by Miss L. Sheldon; Threadworms and Sagitta, by Sir A. E. Shipley, G.B.E., M.A., F.R.S.; Rotifers, by Marcus Hartog, M.A., D.Sc.; Polychaet Worms, by W. Blaxland Benham, D.Sc., M.A.; Earthworms and Leeches, by F. E.

CAMBRIDGE REVIEW.—"Most of the articles are of a very high order of merit—taken as a whole, it may be said that they are by far the best which have as yet been published.... We may say with confidence that the same amount of information, within the same compass, is to be had in no other zoological work."
VOLUME III.
Molluscs, by the Rev. A. H. Cooke, M.A.; Brachiopods (Recent), by Sir A. E. Shipley, M.A., F.R.S.; Brachiopods (Fossil), by F. R. C. Reed, M.A.
TIMES.—"There are very many, not only among educated people who take an interest in science, but even among specialists, who will welcome a work of reasonable compass and handy form containing a trustworthy treatment of the various departments of Natural History by men who are familiar with, and competent to deal with, the latest results of scientific research. Altogether, to judge from this first volume, the Cambridge Natural History promises to fulfil all the expectations that its prospectus holds out."
