TO PROFESSOR LEWIS CAMPBELL.

                                                              Glenlair, Dalbeattie, 3d November 1868.

     I have given considerable thought to the subject of the [346] candidature, and have come to the decision not to  stand. The warm interest which you and other professors have taken in the matter has gratified me very much, and   the idea of following Principal Forbes had also a great effect on my feelings, as well as the prospect of residing  among friends; but I still feel that my proper path does not lie in that direction.—Your afft. friend,

                                                                             J. CLERK MAXWELL.
