My dear Sir

I hear from M^r. Sowerby that the 10 Plates for my volume are ready for Printing off,² & he would be much obliged for the order to this end.

He has had a Fire & suffered some little loss, & would therefore be grateful if in your power to pass his account for ^£23 ’ ^s 10 pretty soon, & let him have the cash.

I wrote sometime since about my not having had some Publications of the Ray Soc. which I fancy are published, but perhaps I am mistaken.—

I am now correcting the 200^th page of my Volume.—

My dear Sir | Your’s very faithfuly | C. Darwin

PS. | Upon reflexion, I think I had better advance, under the circumstances, the money to Sowerby, & then he can hand over to me, your cheque whenever paid to him—³
