DE-. Gardner's Lecture Last Evening" Sr


One of the most interesting lectures of the
season was that delivered last evening by the
above eminent professor, in the Chemical Lecture
Room of the University. A very crowded class
embracing pupils Of different ages, varying from
blooming nineteen, through the "sear and yellow
leat," down to the ''slippered panlaloon' were in
attendance, and seemed quite fascinated with the
opening address of DR.. GARDNER He commenced
on the subject of

be repeated twice q week.
