I wonder if there is an on-line source for Leibniz' correspondence? I have a reference from Dickson's _History of the Theory of Numbers_ to a letter he sent to Johann I Bernoulli. I would be interested in seeing the letter if it's on-line anywhere and, in any case, I would like to know when the letter was actually written. Dickson gives the date of the letter as 1669, which challenges my credulity since Bernoulli was only born in 1667! (Yes, I'm sure Bernoulli was precocious, but not THAT precocious!)
I suppose it's likely a typo and the correct year is 1699. Dickson's reference is not to the current collected writings and letters, but to the _Leibnizens mathematische Schriften_ edited by Gerhardt: Band 3, vol. II, p.601. Any help dating the letter or locating it on-line would be greatly appreciated.
