THIS work was originally intended as an introductory chapter to a treatise I have for some time been preparing for publication on "Softening, and other types of Organic Disease of the Brain."

In consequence of the great and unexpected length to which the contemplated prefatory essay extended, it occurred to me that it would be more consistent with a scientific analysis of the subject to continue my researches, and publish them in a distinct and separate volume, "On the Incipient Symptoms of Obscure Diseases of the Brain, and Disorders of the Mind," as an avant courier, or introduction to the work which is exclusively to relate to the specific and individual types of encephalic disease. Such briefly is the origin of the present treatise.

I have anticipated in the first chapter what, strictly speaking, should have been reserved for prefatory observation. The general design of this work, as well as my estimate of the great importance of the subject analyzed, will be found there fully detailed.
