Mar 3.

My dear Sir

I received a week since your most kind present of your work on Radiolariæ. It is one of the most magnificent works which I have ever seen, & I am proud to possess a copy from the author.

It is very interesting & instructive to study your admirably executed drawings; for I had no idea that animals of such low organization could develope such extremely beautiful structures.—

I hope you are able to work hard on science & thus banish, as far as may be possible, painful remembrances.

With cordial thanks for your magnificent present, & with sincere respect | Believe me my dear Sir | yours very faithfully | Charles Darwin
