Dear Sir

I am much obliged for the kind gift of your Zoolog. atlas. I have not knowledge enough to make any criticisms, but I sh^d. think that the work would be most useful to students. I see only one cause of fear that the clearness of the illustrations, might make some idle students neglect practical anatomy.—¹ Would it not be well to urge this caution on their attention?—

I remain, Dear Sir | Yours faithfully | Ch. Darwin
