To M. J. Berkeley 3 July 
Down Farnborough Kent
My dear Sir
It has occurred to me that you possibly might like to hear how some of my longest soaked seeds get on, so I report to you, that the following have germinated
Beet after 65 days, but
Rhubarb in the cold water
Orache 82 days, cold.—
Oats after 70 days at
Canary seed ordinary temperature
Cress after 70 days but
Lettuce only a few of each have
Radish come up, with a prolonged
Carrott period of germination.
Celery after 85 days.—
This last seems to me a very striking fact.
My dear Sir | Yours very sincerely | Charles Darwin
The Peas you were so very kind as to send me are growing splendidly.—1
Reports success of seed-soaking experiments. Celery and onion germinate after 85 days’ immersion.
