_Principle of Association_ (Vol. iii., p. 424.).--I cannot but doubt
whether "La partie réelle de la métaphysique" means "all that has yet
been done in the philosophy of the human mind." I apprehend it means the
material, or physical part; that which is connected with the structure
of the body. This would apply to Hartley, though not to Mr. Gay: but I
speak in the dark, for I have not that edition of La Place which your
correspondent refers to.
