To J. D. Hooker 18 [September 1869]1
Down. | Beckenham | Kent. S.E.
18th
My dear Hooker
We shall all be right glad to see you this day week; let us know Trains to Orpington & in all probability we can send to meet you.—
I much want a query answered.— Consult any of your colleagues learned in physiology.— When a large piece of bark is removed from a tree, does the bark ever regrow in isolated points, separate from the growing margins of the surrounding bark. I fancy I have heard that this is sometimes the case.— It bears on Pangenesis & on little powers of repair by plants.2
If you can answer in affirmative pray send me a line,—if I do not hear, I shall understand your answer is a negative—.
Yours affect, | C. Darwin
