Anyone who has informed himself through the foregoing as to the great number of diseases and forms of disease that are directly or indirectly connected with tuberculosis, will now be able to estimate the farreaching import of Koch's discovery. It will now be clear to him that pulmonary consumption constitutes only a part, although a great part of tuberculosis and that there are a great many diseases besides that can now be surely cured, it is hoped, with the aid of Koch's method. But this much should be remembered by everyone that this remedy also acts best and surest during the _beginning_ of a disease. We hope that no one will allow valuable time to slip unimproved; it may easily happen that it is too late for successful treatment. Everyone will be able to recognize the symptoms of diseases, which Koch has taught to cure, from the foregoing complete description, and it is better to apply the remedy once too often than miss the proper time for application. Koch's first communications relating to the subject have just been published and will be given unabridged in the following pages. As these communications are written for physicians we will add such explanatory notes as are deemed essential for general intelligence. [Illustration: DR. KOCH IN HIS LABORATORY] THE FIRST COMMUNICATION _Relating to a Method to Cure_ TUBERCULOSIS, BY Prof. R. KOCH, Berlin. In a lecture, delivered by me several months ago, at the International Medical Congress, I referred to a remedy, which makes animal subjects impervious to the inoculation of Tubercle-bacilli, and in the case of diseased animals, checks the progress of the tuberculous disease. In the meantime experiments have been made with human subjects, about which I will report in the following. Originally I intended to complete my investigations and especially gain sufficient experience concerning the practical application of the remedy and its production on a larger scale before I published anything concerning it. In spite of all precautions too much has already been published about it, and that distorted and exaggerated, so that I was obliged, in a way, to prevent false conceptions, to give even now a synopsis of the method as far as it has progressed at the time being. Under present circumstances it must necessarily be short and leave unanswered many important questions.
