Highly honoured Sir!

The interest which your late masterly work on the Power of Movement in Plants shows that you take in the germination (Keimungsgeschichte) of the Cucurbitaceae induces me to take the liberty of sending you my dissertation in which I have touched upon that subject.¹

I may add that I experimented on, and observed, germination in sawdust of the fir tree tribe (Nadelholtz) as early as the spring of 1871, and that since then I have found the germination of many of the different Cucurbitaceae to be on the whole identical.²

I hope to return (to this subject) with additional observations in a treatise to be published later, and to complete my first fruit work at present of a fugitive, and far from lucid character.³
