A Manual of Structural Botany.

By M. C. COOKE, Author of "Seven Sisters of Sleep," &c. "Condensed, yet clear, comprehensive, but brief, it affords to the learner a distinct view."-Globe.

"This excellent little volume was more particularly intended for the use of students in the Botanical Classes established for operatives, into whose hands it was most desirable to place some written record of the lessons they were attending; but its usefulness is by no means limited to such readers, as it forms one of the very best as well as simplest and most comprehensive introductions to Botany we have ever met with. Every difficult scientific word-those great stumbling-blocks to beginners-is not only explained, but well illustrated by a woodcut introduced in the text, so that any misunderstanding of what is meant is rendered impossible, and the learner takes in the lesson doubly enforced: taught, that is, to both mind and eye at once. We are confidently able to recommend the little volume to public favour, its very low price (is.) bringing it within the range of all purchasers.”—Era.

It contains intelligible descriptions of all the terms used in botanical science, with a collection of beautifully-executed illustrations at the end of the volume. To all who do not, but are willing to know the full meaning of such terms as Campylospermous, Sterigmate, and Perichætium, this volume may be safely recommended."-Critic.

"This book affords special facilities for the acquisition of the technicalities of botanical science to such as are not already masters of the dead ianguages. It is illustrated by numerous explanatory diagrams."-The Dial.

The British Fungi

"The author is a thorough mycophagist, well acquainted with the peculiar features by which the most remarkable of the edible kinds of Fungi may be known."Gardener's Chronicle.

"A very readable volume upon the lowest and least generally understood race of plants. For popular purposes the book could not have been better done."-Athe

næum.

"This is a very commendable little book. In the work before us we find associated accurate scientific knowledge, full and satisfactory illustration by coloured lithography and woodcuts, and ample and interesting information.”—Lancet.

"The book is a very useful one, supplying, for a few shillings, information not hitherto attainable except at a much larger cost.”—Field.

"The author of this, at present, the only work written to popularize the study of Fungi, has produced a remarkably neat and well illustrated hand-book to this tribe of plants."-Parthenon.

"Not only plain and easy, but elegantly illustrated.”—Athenæum.

"Mrs. Lankester has given us a handy pocket volume, with a great deal of information about the uses, supposed and real, of the Ferns, and hints for their cultivation."-Guardian.

"A charming little guide to one of the pleasantest of quiet country amusements. It is small, cheap, elegant in form, and illustrated with coloured plates. Its description blends popular with scientific information; there are instructions for drying and collecting, and a glossary of scientific terms. The work is one that may be used by a lady without any previous training as a botanist. It is elegant enough to lie on a drawing-room table, small and light enough to be carried about without trouble in bag or pocket, and referred to by the heath side."-Examiner.

"Mrs. Lankester thoroughly understands how to make her science bend gracefully to common comprehension."-Era.
