My dear Sir

The woodcut¹ will now, I think, do very well: but please observe & take steps to rectify two errors in the spelling of the names of valves.— for upper lateral read Upper capital L Latus for cardinal read Carinal

Please direct all 4 blocks to be cut close for type.

I suppose it will not signify, but I wrote to M^r Bowerbank² for instructions who sh^d. cut the block & suggested to him to leave it in your hands, to get done, & then the drawing & cutting w^d be one charge: if any difficulty arises, I will let you hear.—

Though you had to pay only 1^s/2^d for the parcel I had an extra shilling to pay for porterage; but you will not have any other parcel to send, for, as I said, I will come up to London to compare the proof-sheets of the Engraved Plates, with the specimens.—

I sh^d be greatly obliged if you could inform me (when the time comes) as soon as you know on what day I shall have the proof-engravings, so that I may know a few days before hand when I shall have to come to London.—

There will be no use to send a proof of one Plate before all 4 are ready.—³

I am truly glad that you are making progress

Yours sincerely | C. Darwin

I must see proofs of woodcuts but the Blocks themselves had better be retained by you.—
