Constantly engaged in the treatment of diseases of the female genitals, I had been often foiled in dealing successfully with hysterical and other nervous affections complicating these lesions, without being able to assign a satisfactory cause for the failure. Dr. Brown-Séquard’s researches threw a new light on the subject, and by repeated observation I was led to the conclusion that the cases which had puzzled me, and defied my most carefully-conceived efforts at relief, depended on peripheral excitement of the pudic nerve. I at once subjected this deduction to a surgical test, by removing the cause of excitement. I have repeated the operation again and again, and it is the object of this book to show the results. Daily experience convinces me that all unprejudiced men must adopt, more or less, the practice which I have thus carried out; and I have no doubt that, in properly selected cases, it will prove as successful in their hands as in mine. It will be observed that the majority of the cases I publish have been taken from the records of the London Surgical Home. I have drawn my illustrations chiefly from this source, because the practice of the Institution being freely open to the profession, the cases have been observed by numerous medical men; and, I may add, that many have become firm converts to my views. ON THE CURABILITY OF CERTAIN FORMS OF INSANITY, EPILEPSY, CATALEPSY, AND HYSTERIA IN FEMALES. CHAPTER I. INTRODUCTORY. As the title of this book implies, I do not intend to occupy the attention of my readers with all the numerous varieties of insanity and other nervous disorders to which females are liable, but only those which I believe to be curable by surgical means; nor is it my intention in this category to include slight cases, but to confine myself to such as cause more or less severe functional derangement, or which lead to serious organic lesions. The class of diseases on which I shall dwell are those depending on (or arising from) a loss of nerve tone, caused by continual abnormal irritation of a nerve centre.
