The Biochemical JoUrnal is conductd by the Biochemical Society and is publishedby the Cambridge University Press.

This Society has been instituted for the purpose of facilitating intercourse betweenthose biologists and- chemists wh-o are interested- in the investigation of problemscommon to both, such as the chemiclproblems connected with Agriculture, Brewing,Animal nd Vegetable Physiology and Pathology, &c. Persons interesd in Bio-chemistry are eligible for election.

Meetings are held at different centres for the communication of papers to theSociety.

The annual subsription is 358., which includes a copy of the Journal, and becomes"due on January -1st. Further- information may be obtained on application to theHon. .Sec. Dr P. Hartley, National Institute for MMedicl Research, Mount Vernon,mpstad,Lndon, N.W. 3, or to the Hon. Treas., Mr J. Addyman Gardner, 13 Campden

Grove, Kensington, W. 8, to whom subscriptions should be sent.Papers for publication should be sent to Prof. A.-Harden,. F.R.S., Lster Institute,

Chelsea Gardens, S.W. I. Communications respecting the printing of the articles, orrespecting the purchase o; offprints should be addresed to the University Press,Cambridge..

The Journal is issued about every two months and the date'at which each paperis received by the editors is printed at-the beginning of the paper.

All communications respectinrg the purchase of copies of the parts or volum,whether _current or back issues, or respecting subscriptions in the case of non-members of the Biochemical Society (£3 net per volume (post free) payable inadvance) should be addressed to The Cambridge University Press, Fetter Lane, LIondon,E.C. 4, or to the Hon. Treas., Mr J. Addyman Gardner, 13 Campden Grove, Kensington,W. 8.

offered to any other Journal for prior- or simultaneous publication.:3. All communications intended for publication must be type-written.4;. References. References to literature- should be' arrnged alphab-etically

according to authors' names at the end of the: communication, each accompaniedby the date, title-of Journal,-volume and page, thus: Ackermann (1912, 1), Zeit8ch.«Bio. 59, 17. I[n the tet the reference should be indicated by the Aautr's name andthe date, enclosed- i- brackets, thus fAckermann, 1912, 11. If reference: is made toseveral papers published by one author in a-single year, these should-be numberedin sequence and thel number quoted along with the year- both ihn the text and in thecollected' references.

5. Chemical formulae should be written, as far as possible, in a single horizontal line.6. Illustrations and -curves accompanying the- papers must be carefully drawn,

about- twice the size of the- finished, block, on smooth white Bristol boards in-Indianink. Any lettering on- these drawings shtiold be lightly inserte in pceicil. Furtherinformation can be obtained.from- the Editors.

-MSS. f-or the' successive numbers of Vol. 20 should be in thehands, of the Editors- before-the 1st of January, ,Mach, May, July,September) and- November respectively. -Contributors8 are speciallyrequested -to arrange .references in the manner uniformly adopted inthiss Journal.
