[All Rights are Reserved.] ΤΟ SIR WILLIAM JENNER, BART., M.D., D.C.L., F.R.S., I Dedicate this Book. HOW MUCH I OWE TO HIS TEACHING I CANNOT ESTIMATE, BUT THE EXAMPLE HE HAS SET ME OF PURITY OF PURPOSE AND OF UNFLAGGING INDUSTRY HAS ENCOURAGED ME TO PERSEVERE AGAINST DIFFICULTY WHILE THE ENJOYMENT OF HIS FRIENDSHIP HAS BEEN FOR TWELVE YEARS A SOURCE OF THE HIGHEST HAPPINESS TO ME. BERKELEY HILL. PREFACE. I HAVE attempted to arrange in a systematic description of Venereal Diseases, the large contributions which recent research has brought to our knowledge. In doing so I have striven to render the work complete, while keeping it concise and suitable for the student as well as the practitioner. As the Syphilitic virus is not now supposed to be the cause of all venereal sores, the local contagious ulcer, or chancre, is treated in a separate division of the book. Syphilis is a constitutional disorder from the first : the effects of the virus may penetrate every organ of the body while the disease is in progress, and continue perceptible until the poison grows inert or languishes in some local sequela. Not long ago it was impossible to describe the whole course of Syphilis, for it is only recently that we have been able to assign to their true origin the numerous lesions which are now recognised as common sequences of the disease. b |
