My dear M^r Sclater

I send today two sheets, but the first few pages do not relate to Birds. I hope the corrections will not much interfere with the facity of reading.²

Kindly look to footnotes, as they often include names. If you find only names to correct (which is almost too good to be hoped for) please return the sheets to M^essrs. Clowes, whose address is given at foot of first page, as this will save time.³ If there are more serious corrections please return the sheets here

You will save me from making many disgraceful misspellings, which would have been widely spread, for 5 foreign editions are now preparing.⁴

Yours very gratefully | Ch. Darwin
