Though now he is renowned as an experimentalist,
Benjamin Franklin's formulation of a general theory of electrical

Franklin responds to a number of his friend's questions about
electricity and the Leyden jar, an early form of electrical condenser.
In a document that is more a draft scientific
report than a letter, it appears that Franklin wrote his answers

the questions, which he wrote in red ink.
