My dear M^r Sclater,

I send by this post 3 sheets, & tomorrow I will send another. This, with the exception of about $\frac{3}{4}$ of a sheet, completes the part on birds, & I sincerely congratulate you and thank you for your labour will then be completed.¹ Some of the sheets are terribly corrected, but they are chiefly parts in which few names are included. I am so tired with my work that I shall leave this place before post time on Thursday the 8^th, & shall stay at “6 Queen Anne Street” for a week.² I will call some early day to see you.

Yours very truly obliged | Ch. Darwin
