To J. D. Cooper   22 February 1882

Down, | Beckenham, Kent.

Feb 22— 1882

My dear Sir

I now send two other drawings to be engraved, and please to attend to the following instructions.1

Both drawings to be reduced to 23 of present scale.

They are to stand as shown by the pencil bounding square   They are highly magnified sections, therefore all the lines must be very fine.

You will see that in fig. 1 that some of the cells in the space marked c contain many rounded granules & these must be attended to in the cuts. These are closer together in the long cells marked b.

In the exterior cells marked d, and in the cut-off root-hairs, marked e the granules are to be omitted as I have written down.

The tubes or ducts marked a are crossed by fine transverse lines.

The same remarks apply to fig 2, but here the granules, & small spheres and elongated masses in the cells d and in the root hairs e are to be carefully shown.

The letters a, b, c, d, e are to be engraved in both figs. where now placed   The blocks had better be sent to me when drawn; and I particularly beg you to have them done as soon as possible

My dear Sir | Yours sincerely | Ch. Darwin
