MY LORDS AND GENTLEMEN, The following OBSERVATIONS are respectfully submitted to YOUR notice, as the vigilant and humane Guardians of an _Institution_ which performs much good to society, by diminishing the SEVEREST amongst human calamities, By, My LORDS and GENTLEMEN, Your very obedient and humble Servant, THE AUTHOR. PREFACE. As the office I hold affords me abundant means of acquiring information on the subject of mental disorders, I should feel myself unworthy of that situation, were I to neglect any opportunity of accumulating such knowledge, or of communicating to the public any thing which might promise to be of advantage to mankind. The candid reader is therefore requested to accept this sentiment, as the best apology I can offer for the present production. It has been somewhere observed, that in our own country more books on Insanity have been published than in any other; and, if the remark be just, it is certainly discouraging to him who proposes to add to their number. It must, however, be acknowledged, that we are but little indebted to those who have been most capable of affording us instruction; for, if we except the late Dr. JOHN MONRO'S Reply to Dr. BATTIE'S Treatise on Madness, there is no work on the subject of mental alienation which has been delivered on the authority of extensive observation and practice. It is not intended to present the following sheets as a treatise, or compleat disquisition on the subject, but merely as remarks, which have occurred during the treatment of several hundred patients. As a knowledge of the structure, and functions of the body, have been held indispensably necessary in order to become acquainted with its diseases, and to a scientific mode of treating them; so it would appear, that he who proposes to write on Madness should be well informed concerning the powers and operations of the human mind: but the various and discordant opinions, which have prevailed in this department of knowledge, have led me to disentangle myself as quickly as possible from the perplexity of metaphysical mazes.
