Preface.

_The alarming increase of Insanity, as might naturally be expected, has

incited many persons to an investigation of this disease;--some for the

advancement of Science, and others with the hope of emolument._

_More than ten years having elapsed since the publication of the

"Observations on Insanity," a trifle, which the Profession has held in

greater estimation than its intrinsic merits could justify: the present

work is modestly introduced to the public notice, as a corrected copy of

the former, with considerable additions, which the extensive scope of

Bethlem Hospital would have furnished more liberally to a more intelligent

observer._

_To have taken a comprehensive survey of the human faculties in their

sound state; to have exhibited them impaired by natural decay, and

transformed by disease, would have implied an ability to which I cannot

pretend; would have required many volumes to unfold, and perhaps more

patience than any rational experience could have attributed to the reader.

The contents of the following pages are therefore to be considered as an

abbreviated relation, and condensed display of many years observation and

practice, in a situation affording constant opportunities and abundant

supplies for such investigations._

_It is natural to presume, that amongst my professional acquaintance the

subject of Insanity must have been frequently introduced as a topic of

discourse; and I am ready to acknowledge, that I have often profited by

their remarks and suggestions: but I should be ungrateful were I not to

confess my particular obligations to my esteemed friend, Anthony Carlisle,

Esq. Surgeon to the Westminster Hospital, for many corrections, and some

communications, which I shall ever value as judicious and important._
