| [1230] In a footnote to Fontaine’s description of Jurassic plants |

| of Oregon, Lester Ward writes:—“Seward treats _Sagenopteris_ as a |

| fern, classing it now (_Jur. Fl. Yorkshire Coast_, 1900, p. 161) in |

| the family Polypodiaceae, although in his _Wealden Flora_, 1894, p. |

| 129, he placed it in the Schizaeaceae.” [Ward (05) p. 83, note _b_. |

| My words are “I am disposed to regard _Sagenopteris_ as probably a |

| genus of ferns” (_loc. cit._ 1900, p. 161). I have never referred |

| this plant to the Polypodiaceae or Schizaeaceae or to any other |

| family. |

CAMBRIDGE: PRINTED BY JOHN CLAY, M.A. AT THE UNIVERSITY PRESS.

CAMBRIDGE BIOLOGICAL SERIES

General Editor, A. E. SHIPLEY, M.A., F.R.S.,

Master of Christ’s College.

=A Text-Book of Zoogeography.= By FRANK E. BEDDARD, M. A., F.R.S.,

Prosector of the Zoological Society of London. Crown 8vo. With 5

maps. 6_s._

=The Elements of Botany.= By FRANCIS DARWIN, Sc.D., M.B., F.R.S.,

Fellow of Christ’s College. _Second edition._ Crown 8vo. With 94

illustrations. 4_s._ 6_d._

_Journal of Education._ A noteworthy addition to our botanical

literature.

=Practical Physiology of Plants.= By FRANCIS DARWIN, Sc.D., F.R.S., and

E. HAMILTON ACTON, M.A. Crown 8vo. With 45 illustrations. _Third

edition._ 4_s._ 6_d._

_Nature._ The authors are much to be congratulated on their work, which

fills a serious gap in the botanical literature of this country.

=Morphology and Anthropology.= By W. L. H. DUCKWORTH, M.A., M.D.,

Fellow and Lecturer of Jesus College, University Lecturer in

Physical Anthropology. Demy 8vo. With 333 illustrations. 15_s. net._

_Athenæum._ Mr Duckworth has managed to produce in his “Morphology and

Anthropology” just such a text-book as students have long been asking

for.... It is no easy task to have undertaken such a work and the

author is to be congratulated on the success which has attended his

efforts. The volume can be confidently recommended to all whose studies

lead them in this direction.

=Lectures on the History of Physiology= during the Sixteenth,

Seventeenth and Eighteenth Centuries. By Sir M. FOSTER, K.C.B.,

M.D., D.C.L. Demy 8vo. With a frontispiece. 9_s._

_Nature._ There is no more fascinating chapter in the history of

science than that which deals with physiology, but a concise and at

the same time compendious account of the early history of the subject

has never before been presented to the English reader. Physiologists

therefore owe a debt of gratitude to Sir Michael Foster for supplying

a want which was widely felt.... No higher praise can be given to the

book than to say that it is worthy of the reputation of its author.

=The Soluble Ferments and Fermentation.= By J. REYNOLDS GREEN, Sc.D.,

F.R.S., Professor of Botany to the Pharmaceutical Society of Great

Britain. _Second edition._ Demy 8vo. 12_s._

_Nature._ It is not necessary to recommend the perusal of the book to

all interested in the subject since it is indispensable to them, and

we will merely conclude by congratulating the Cambridge University

Press on having added to their admirable series of Natural Science

Manuals an eminently successful work on so important and difficult a

theme, and the author on having written a treatise cleverly conceived,

industriously and ably worked out, and on the whole, well written.

=A Treatise on the British Freshwater Algæ.= By G. S. WEST, M.A.,

A.R.C.S., F.L.S., Lecturer in Botany in the University of

Birmingham. Demy 8vo. With a frontispiece and 166 illustrations.

10_s._ 6_d._ _net_.

_Nature._ Its aim is stated as “to give the student a concise account

of the structure, habits and life-histories of Freshwater Algæ, and

also to enable him to place within the prescribed limits of a genus

any Algæ he may find in the freshwater of the British Islands.” To do

this within the limits of an octavo volume of less than 400 pages, in

which are numerous illustrations, is a task possible of accomplishment

only by one very familiar with the subject and skilled in concise

expression; but that it has been successfully done will, we think,

be the verdict after testing the book thoroughly.... Prof. West’s

treatment of his subject is instructive and stimulating.

=A Manual and Dictionary of the Flowering Plants and Ferns.= By J. C.

WILLIS, M.A., Sc.D., Director of the Royal Botanic Gardens, Ceylon.

_Third edition._ Crown 8vo. 10_s._ 6_d._

_Field._ Taking this handy volume and a local flora, the traveller

or student may do an enormous amount of practical field work without

any other botanical literature whatever.... The result is a work that

ought to be included in every library of botany and horticulture or

agriculture, and it is certainly one that the nomadic botanist cannot

afford to leave at home.... We have used the original edition of this

work since its publication, and have found it to be one of the most

useful and comprehensive works on plants ever produced.

_Athenæum._ The whole is well abreast of modern research, and a

thoroughly business-like volume, lucid though compact.

=Agriculture in the Tropics.= An elementary Treatise. By J. C. WILLIS,

M.A., Sc.D. Demy 8vo. With 25 plates. 7_s._ 6_d._ _net._

=Palæontology—Invertebrate.= By HENRY WOODS, M.A., F.G.S., University

Lecturer in Palæozoology. Crown 8vo. _Fourth edition._ With 151

illustrations. 6_s._

=Outlines of Vertebrate Palæontology for students of Zoology.= By

ARTHUR SMITH WOODWARD, M.A., F.R.S., Keeper of the Department of

Geology in the British Museum. Demy 8vo. With 228 illustrations.

14_s._

_Athenæum._ The author is to be congratulated on having produced a work

of exceptional value, dealing with a difficult subject in a thoroughly

sound manner.
