Major There Brandt, whose therapeutic invention I have tried to establish on a scientific basis and to elucidate in this book in the simplest possible manner. The dear features of my “old friend,” as he was wont to sign himself in his frequent epistolary correspondence with me, impart life to the cold letters, thus creating the impression in the mind of the reader as if he himself were speaking to us. Mr. Brandt, an ever-active, restless man, died in August, 1895, at the age of seventy-three years, in the midst of his professional and literary pursuits. He was ever desirous both of learning and teaching. Up to his death he kept up an instructive scientific correspondence with the author. For more than a year, now, he has been reposing in his last resting place. To give this method the largest possible publicity for the benefit of suffering women, is immeasurably better than the erection of a monument, and in all likelihood more according to the wishes of this remarkable man. In this sense, therefore, I warmly press the hand of the translator, Dr. Westerschulte, across the Atlantic Ocean. My method differs essentially from that laid down in numerous other works on this subject. Proceeding from the simple to the complicated, not only the method per se, but also the diseases indicated are described; whereas, the other works at most give only extracts of Brandt’s own book about his method, or simply contain more or less practical suggestions for the modification of a part of the method.
