CAMBRIDGE AGRICULTURAL MONOGRAPHS

General Editors: T. B. Wood, M.A., Draper’s Professor of Agriculture in the University of Cambridge, and E. J. Russell, D.Sc., Director of the Rothamsted Experimental Station, Harpenden, Herts.

Each volume of this series will contain a summary of the present position on some particular aspect or branch of agricultural science by an expert of acknowledged authority.

The treatment will be critical and impartial, and sufficiently detailed on all points of fundamental importance to be of use alike to all readers, but especially to those who are not in touch with an institution possessing a well equipped reference library. Full references will be given, and a bibliography attached for the benefit of those who wish to follow up any particular point.

The following volumes are in preparation:

The Strength of Wheat Flour. By Professor T. B. Wood, M.A.
The Constitution of the Soil. By E. J. Russell, D.Sc.
Disease Resistance. By R. H. Biffen, M.A., F.R.S., Professor of Agricultural Botany in the University of Cambridge.
Poisonous Plants. By H. C. Long.

THE CAMBRIDGE FARM INSTITUTE SERIES

General Editors: Professor T. B. Wood, M.A., and E. J. Russell, D.Sc.

The volumes of this series are intended to meet the needs of the many Farm Institutes already in existence or about to be formed. They are intended for the average student whose object is to farm, rather than for the exceptional man who wishes to become an agricultural expert.

Every endeavour will be made to attain a high standard educationally, by training students to take an intelligent interest in their daily work and to appreciate the beauty of the common objects among which their life will be passed. On the other hand the fact that farm students must earn their living on the land will not be lost sight of.

The following will be among the first volumes:

Farm Accounts. By C. S. Orwin. [Now ready
Plant Life in Farm and Garden. By Professor R. H. Biffen, M.A.
The Feeding of Farm Animals. By Professor T. B. Wood, M.A.
A Student’s Book about Soils and Fertilizers. By E. J. Russell, D.Sc.
Common Fungus and Insect Foes. By F. R. Petherbridge, M.A.

SELECTION FROM THE GENERAL CATALOGUE OF BOOKS PUBLISHED BY THE CAMBRIDGE UNIVERSITY PRESS

THE CAMBRIDGE BRITISH FLORA

By C. E. Moss, D.Sc., F.L.S., assisted by specialists in certain genera. Illustrated from drawings by E. W. Hunnybun. The work will be completed in about ten volumes. Volume II is now ready.

The styles of binding and the prices will be as follows:

	Published Price per volume	Price per volume to subscribers to the whole work
Paper boards, with canvas back and paper label, each volume in two parts, the first containing the text and the second the plates	£2 10s net	£2 5s net
Quarter morocco, in two parts divided as above	£6 net	£5 5s net
Paper boards, with canvas back and paper label, in one volume, the plates mounted on guards and bound interspersed with the text	£3 net	£2 15s net
Quarter morocco, in one volume, the plates mounted on guards and bound interspersed with the text	£6 net	£5 5s net

“The appearance of Dr Moss’s work has been anticipated by British botanists with the greatest interest; not only to them does it appeal, for its completeness and attention to detail entitle it to rank among works of Continental importance. The Cambridge University Press has been fortunate in securing the services of Dr Moss, than whom no one more competent for the task could be found. By a combination as admirable as it is rare, Dr Moss is at once an acute field botanist, a diligent investigator of herbaria, and a student of botanical literature.... Mr Hunnybun’s drawings are all made from living plants, so that the work may be regarded as representing more fully than has been hitherto done our knowledge of British Botany at the present day.”—Journal of Botany.

FOOTNOTES:

[ [1] This idea of a selectivity of the roots has been recently revived by [Colin and Lavison (1910)] who found that when peas were grown in the presence of barium, strontium or calcium salts no trace of barium could be found in the stem, strontium only occurred in small quantities, while calcium was present in abundance. They concluded that apparently salts of the two latter alkaline metals could be absorbed by the roots and transferred to the stem and other organs, but that this is not the case with salts of barium. They obtained similar results with other plants, beans, lentils, lupins, maize, wheat, hyacinth. Their proof is not rigid, and exception could be taken to it on chemical grounds.

[ [2] Vide [Daubeny, Journ. Chem. Soc. (1862), p. 210].

[ [3] These are “grains of Paradise,” Guinea grains, or meleguetta pepper. They are the seeds of Amomum melegueta and A. Granum-Paradisi, N.O. Zingiberaceae.

[ [4] The English translation in Just’s Bot. Jahresber. speaks only of a “solution of copper,” and in no case is the specific compound mentioned.

[ [5] 44 mg. ZnSO₄ . 7H₂O = 10 mg. Zn = 1/22,727 ZnSO₄ . 7H₂O approx.

[ [6] This is equivalent to about ·1% of poison.

[ [7] m probably = gram molecular weight.

[ [8] 0^{µ gr.}, 1 = 0·0001 mg.

[ [9] 30 grams arsenious acid to 30·7 “cubik Decimeter” soil = about ·1%.

[ [10] In the present state of our knowledge such a concentration seems relatively strong!

[ [11] The exact compound is not specified in the abstracted paper, ¹⁄₁₀₀₀–¹⁄₁₀₀% Natr. Ars. being given.

[ [12] According to Engler’s classification this plant belongs to N.O. Myrsinaceae.

[ [13] “Il apparaît donc que les graines fournies par des plantes ayant crû en présence d’une quantité de bore élevée présentent une accoutumance vis-à-vis de cet élément; les plants auxquels elles donnent naissance semblent non seulement faire un meilleur emploi des petites doses de bore qui leur sont offertes, mais encore supportent les doses toxiques plus facilement que les plants témoins, issus de graines non accoutumées.”

[ [14] As no analysis of the mineral is given it is obviously impossible to say to what constituent the increase is due in this case.
