breeds of pigeons about the wing bars. I SUSPECT it will throw light on the colour of the primeval horse. So do help me if occasion turns up...My health has been lately very bad from overwork, and on Tuesday I go for a fortnight's hydropathy. My work is everlasting. Farewell.
My dear Fox, I trust you are well. Farewell, C. DARWIN.
CHARLES DARWIN TO J.D. HOOKER. Moor Park, Farnham [April 26th, 1858].
...I have just had the innermost cockles of my heart rejoiced by a letter from Lyell. I said to him (or he to me) that I believed from the character of the flora of the Azores, that icebergs must have been stranded there; and that I expected erratic boulders would be detected embedded between the upheaved lava-beds; and I got Lyell to write to Hartung to ask, and now H. says my question explains what had astounded him, viz., large boulders (and some polished) of mica-schist, quartz, sandstone, etc., some embedded, and some 40 and 50 feet above the level of the sea, so that he had inferred that they had not been brought as ballast. Is this not beautiful?
