Unnecessary severity is criminal

Let it be indelibly impressed on the physician and attendants, that all the fury, disposition to mischief, attempts to injure, and all the noise and exertions of maniacs, as well as their abuse, keen sarcastic, cutting observations, &c. are the result of disease, and ought to be allowed for accordingly, and imputed to this source; that any virulence of expression should never be regarded by the attendants or physician; nor injury or violence inflicted on them be resented or returned; unnecessary severity is unmanly and highly criminal.
