Thanks for AG's trouble about the seeds. Is curious to see their germination and the early seedling growth.
Asks for cotton seeds, as he observes odd movements of the cotyledon.

My dear Gray
It is uncommonly good of you to have taken so much trouble about the seeds; but it makes me feel rather guilty, for though I was very curious to see them germinate, yet the points in question were not of much importance. Ipomœa leptophylla has not yet germinated, but I have a good many seeds to sow again in the early spring, if those already sown do not germinate; & I have often suspected that some kinds of seeds have an obstinate inherited habit of not germinating & dying if sown in the winter.— I have just put 5 of the seeds of Megarrhiza to soak, but only one sinks & this alarms me.— I very much want to see whether the curious heel-like projection at the base of the hypocotyledonous stem, described by Flahault, & which splits the seed-coats so beautifully in other Cucurbitaceæ, is here absent, as I hope & as ought to be the case as the cotyledons are not withdrawn from the seed-coats.
Now do not waste your very valuable time, but if you c
