To Fritz Müller   16 May 1878

My dear Sir

Your letter just received is highly interesting, & I have forwarded it to M^r Meldola, who is Sec^y. to the Entomolog. Soc., & no doubt will be delighted to read extracts at the next meeting.¹ I am astonished at the many new & curious facts which you continually observe.

Many thanks for the information about the Mimosa; when it is in flower, will you kindly send me a few dried flowers & leaves that I may get the species named.² At any time when walking in the rain, & you sh^d pass near a Cassia, please to observe whether the leaves are all deflexed.

I was very glad to receive the seeds of Cassia neglecta; but the greater number were destroyed by a curious beetle, which had been developed & were alive in the packet. I sent this beetle to the Entomol. Soc.³

When next you write, please to tell me whether Cassia neglecta is the species which grows near the sea-side, of which you before sent me seeds.⁴

In my former letter I said that none of the seeds of Pontederia had germinated; but now 4 seedlings have come up!!⁵

With cordial thanks for all your great kindness, I remain | my dear Sir | yours sincerely | Charles Darwin

I am very sorry to hear about the yellow Fever.—⁶
