Autograph letter signed : Aberdeen, to William Angus Knight, 1887 March 8.

Thanking Knight for sending a copy of his book on David Hume; making two "critical observations" about the book and clarifications that he believes should be made in it: first, that Hume's name does not appear in the records of classes at Edinburgh University, and that therefore evidence is lacking to prove that he attended classes there, and second, that Hume's practices as a historian were suspect, to the point of "conscious dishonesty", as John Stuart Mill attested to in an article that Bain referred to in his own book on Mill; writing "It is a fact that neither of the Mills paid any attention to Hume's philosophic writings, much as they are talked of as continuing his opinions in philosophy"; offering to send Knight his books on the Mills; sending him a copy of his recently published volume "On Teaching English".
