Scope and content

7 Camden Street, Camden - Whewell is to receive a copy of De Morgan's paper on logic. He has Sir William Hamilton's system of logic in the work of Hamilton's pupil, Thomas S. Baynes, An Essay on the New Analytic of Logical Forms. The requisites of this essay made the foundation of Hamilton's charge on him of intellectual theft. He and Boole come in for a lecture against meddling with logic with help of mathematics. He asks Whewell to read it and inform him 'if these things will strike others as being as monstrous as they do me' De Morgan will next look at 'the relation between the laws of enunciation and the laws of thought', and reminds WW of their former discussion on enunciation.
