My dear Sir

The enclosed M.S. will occupy as nearly as I can calculate 330 pages of size of that used by D^r. Baird: there will be preface, index & description of Plates.—¹

I have enclosed instructions which you can read to M^ess. Adlard on all points, except size of type.— My M.S. looks atrociously bad, but the Printers make it out better than you could believe possible: I offered to the Pal. Soc. (& do to you) to pay for corrections, if heavier than the average high corrections; I had not, however, to pay anything.—

I most urgently desire, & trusting I may be permitted, have so instructed M^ss. Adlard, to print 3 of the woodcuts, explanatory of the nomenclature used, on a separate folding Page, so as to be easily accessible to the Reader.—²

I think I told you that I have failed (after repeated attempts, in getting any of the Plates coloured, which required fresh specimens: but I have, (partly in consequence) had 10 instead of 8 Plates engraved: if this costs the Soc^y. more than the estimated colouring of the Plates, I am bound & will pay as much as the Council may direct; but I do not wish to pay more than such excess, if the Council are pleased to admit of this arrangement, as the preparatory drawings have cost me ^£10.— Will you be so kind as to lay this part of my letter before the Council.

I should be grateful if you would urge M^ss. Adlard to print the M.S. as quickly as possible; as I shall do nothing till the volume is printed off.

I will send my servant in about 8 or 9 days to you, to take the M.S to M^ss Adlard: but I will send a line to say on which day he will call.— My address in London till the 9^th or 10^th, is “7. Park St Grosvenor Sq^r.”—³

Dear Sir | With thanks | Yours very faithfuly | C. Darwin D^r Lankester.

P.S. | I hope the Council will be enabled to arrange to print the second vol. of my Cirripedia at the end of the ensuing year, by which time the M.S. will be ready.—⁴ Probably they will be able to judge better, after the present vol. is published, how many Plates, they can afford me.

I do hope the present volume will be worthy of the Ray. Soc^y.

P.S. I presume you received my subscription⁵ by Post office order for current year, but forgot to acknowledge it, in your obliging note received yesterday.
