Anthony Babington.
—Can any of your correspondents inform me whether William Kempe's Dutiful Invective against the moste Haynous Treasons of Ballard and Babington, &c. &c., has been reprinted in any collection of rare tracts, or otherwise? and also whether his Censure of a loyall Subiect upon certaine noted Speeches and Behaviour of those 14 notable Traitors (Ballard, Babington, &c.), has also been reprinted?
I should also be glad of references to any other tracts or ballads referring to Babington and his conspiracy.

Sir Isaac Newton, Cicero, and Gravitation.
—How is it that Sir Isaac Newton has obtained so world-wide a renown for his discovery of the law of gravitation, when the following passage in the Tusculan Disputations proves it to have been well known to Cicero?
"Qua omnia delata gravitate medium mundi locum semper expetant."
