The main journals of the Royal Society, the Philosophical Transactions and Proceedings, from Volume One, Issue One in March 1665, have been put online, but they will only be free until December.

Also great fun for browsing. In the first volume, I came across the account from the great Robert Boyle:

By the same Noble person was lately communicated to the Royal Society an Account of a very Odd Monstrous Birth, produced at Limmington in Hampshire, where a Butcher, having caused a Cow (which cast her Calf the year before) to be covered, that she might the sooner he fatted, killed her when fat, and opening the Womb, which he found heavy to admiration, saw in it a Calf, which had begun to have hair, whose hinder Leggs had no Joynts, and whose Tongue was, Cerberus-like, triple, to eash side of his Mouth one, and one in the midst. Between the Fore-leggs and the Hinder-leggs was a great Stone, on which the Calf rid … The Stone, according to the Letter of Mr David Thomas, who sent this Account to Mr Boyle, is with Doctor Haughteyn of Salisbury, to whom he also referreth for further Information.

This struck me as a fascinating combination of early attempts at a scientific method – sources of information and pre-existing circumstances are carefully detailed – with what in the end amounts to exactly the same contents as the popular pamphlets that described similar events. Although I suppose they aren’t trying to draw a political or religious message from them, as a pamphlet would.
