Dear Sir

I write merely to thank you for your note & information, & to express a hope that you may receive benefit from your present residence. I had previously heard of the Australian caterpillars; but no one knows how they cause such severe pain.¹ In Africa there is a species believed to belong to the same genus, which is so venomous that if a hand touches a surface previously touched by the caterpillar, dreadful inflammation follows over nearly the whole surface of the body.

With my thanks & hopes for your recovery I remain | dear Sir | yours faithfully | Ch. Darwin
