In the ordinary experience of psychological physicians, whose sphere of observation is largely in private practice and within the walls of an asylum for the middle and higher classes of society, many circumstances arise which do not present themselves, at least with the same distinctness and prominence, to those whose experience may be upon a much more extensive scale, yet almost exclusively among the artisan and pauper classes of the community, in large public institutions. The reports and the disquisitions with which the medical superintendents of these latter establishments enrich, from time to time, the records of psychological medicine need no commendation from individuals; the profession have fixed their value; and it is universally conceded, indeed, that from psychologists and philanthropists alike they justly claim the very highest measure of approval.
