"The irritability formerly considered to be peculiarly characteristic of doctors, poets, and painters, is a disease, says Dr. Gibson, seldom seen, except among hot and rebellious graduates, fresh from the schools. The courtesy and respect which have appeared to distinguish your intercommunications as students, indicate the honorable, frank, and straight-forward course of conduct which will distinguish your future professional career. Professional etiquette, gentlemen, sums itself up in one great golden precept."
