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.”

FIELD.- -“The Cambridge Natural History series of volumes is one of very great value to all students of biological science. The books are not intended for popular reading, but for utilisation by those who are desirous of making themselves thoroughly acquainted with the branches of zoology of which they treat.”

KNOWLEDGE.—“If succeeding volumes are like this one, the Cambridge Natural History will rank as one of the finest works on natural history ever published.”

ATHENÆUM. -" The series certainly ought not to be restricted in its circulation to lecturers and students only ; and, if the forthcoming volumes reach the standard of the one here under notice, the success of the enterprise should be assured.”

SCIENCE GOSSIP.—“Every library, school, and college in the country should possess this work, which is of the highest educational value.'

Mr. F. G. AFLALO IN COUNTRY LIFE.-"The editors will, on the completion of the series, have the satisfaction of contemplating a work with which, for thoroughness and interest, no other of recent appearance can compare."
