Excerpt from On Obscure Diseases of the Brain, Disorders of the Mind: Their Incipient Symptoms, Pathology, Diagnosis, Treatment, and Prophylaxis 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 indi vidual 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 re served for prefatory observation. The general design of this work, as well as my estimate of the great importance of the subject analysed, will be found there fully detailed.
