From Charles Dixon   19 January 1880

Sir

Some few days ago I happened to be dissecting a Common Heron, shot on one of the streams near this place. Upon examining its plumage I found the inclosed seed firmly fastened among the breast feathers. I consider this another instance as to how seeds are conveyed from one place to another. Doubtless when the bird preened its plumage the seed would have been cast forth, to germinate or not according to circumstances.¹

There are many other seeds which depend upon animals and birds, too, for dispersal, by sticking firmly to the fur or feathers of a bird or animal walking amongst the plants.

I trust, sir, that you will excuse me troubling you on the matter, and let my enthusiastic desire for assisting in working out Nature’s problems, be my apology for bringing before your notice what seems such a trivial circumstance.

Believe me, Sir, | Very respcty yours | Charles Dixon
