Every step in scientific investigation, every proposition which relates to the interest and happiness of man, every statement and appeal involving a valuable consideration, must be submitted to the scrutiny and judgment of individual reason; for every person has the right to form his own conclusions, and justify them by experience. Those claims which are only supported by empty assertion are very doubtful. Misty theories vanish before the sun of truth. He who renders professional services cannot be successful, unless he be sustained by real merit.
TREATING PATIENTS WHO RESIDE AT A DISTANCE.
We can treat many chronic diseases as successfully without as with a personal consultation, as our vast experience enables us to correctly determine the malady from which the patient is suffering, from a history of the symptoms, and answers to questions furnished. We have not seen one person in five hundred of those whom we have cured.
Some may suppose that a physician cannot obtain, through correspondence, a sufficiently accurate idea of the condition of a patient to enable him to treat the case successfully; but a large experience in this practice has proved the contrary to be true, for some of the most remarkable cures have been effected through the medium of correspondence. In most long-continued cases, the patient has thought over his symptoms hundreds of times. The location of every pain, whether acute or mild, constant or occasional, and the circumstances under which it occurs, have been carefully noted. He has observed whether he had a rush of blood to the head, was feverish or chilly, whether troubled with cold hands and feet, whether full of blood, or pale and bloodless; and he states these matters with accuracy and common sense when writing to us, for he has a very good, if not a professional, knowledge of the relative importance of these symptoms. So in regard to digestion, he states what kinds of food agree with him, or whether he is troubled with excessive acidity or a flatulent condition of the stomach. He also informs us whether his tongue is coated and bilious, or clean and healthy, and gives many other particulars too various to enumerate, by which we are enabled to gain a perfect understanding of the case. If his description be not sufficiently complete to enable us to obtain a definite understanding of the case, he is requested to answer a list of important questions which are sent him. The people are far more intelligent in these matters than physicians are generally willing to admit. A patient is often confused while being personally examined by a physician, and gives imperfect or incorrect answers. After he has left the presence of the physician, he finds that he has failed to enumerate many of the most important symptoms. In consulting by letter, the patient is not embarrassed, he states the exact symptoms, and carefully reads over the letter to see if it is a complete and accurate description of his sufferings. In this way he conveys a much better idea of the case than if present in person, and subjected to the most thorough questioning and cross-examination. The timid lady and nervous young man write just as they feel; and one important reason why we have had such superior success in treating intricate and delicate diseases, is because we have obtained such true and natural statements of the cases from these letters, many of which are perfect pen-pictures of disease. As bank-tellers and cashiers, who daily handle large quantities of currency, can infallibly detect spurious money by a glance at the engraving or a touch of the paper, so the experienced physician, by his great familiarity with disease, becomes equally skilled in detecting the nature and extent of a chronic malady from a written description of its symptoms.
URINARY SIGNS.
A careful microscopical examination and chemical analysis of the urine is a valuable aid in determining the nature of many chronic diseases, particularly those of the nervous system, blood, liver, kidneys, bladder, prostate gland and generative organs. This important fact is not overlooked at the Invalids' Hotel and Surgical Institute, where an experienced chemist is employed to make such examinations and report the result to the attending physicians. Medical authors, professors, and practitioners of all schools, admit and even insist upon the importance of such examinations in diagnosticating diseases. Many practitioners neglect to take advantage of this invaluable aid, while others fear that if they attach much importance to such examinations they will be ranked with "uroscopian" or "water" doctors, a class of enthusiasts who claim to be able to correctly diagnosticate every disease by an examination of the urine. Persons consulting us and wishing to avail themselves of the advantages afforded by these examinations can send small vials of their urine by express. The vials should be carefully packed in saw-dust or paper and enclosed in a light wooden box. All charges for transportation must be prepaid, and a complete history of the case including the age and sex of the patient, must accompany each package, or it will receive no attention. This saves valuable time by directing the examination into the channels indicated, thus avoiding a lengthy series of experiments. As we are daily receiving numerous vials of urine, every sample should, to prevent confusion, be labeled with the patient's name.
There is a natural, definite proportion of the component elements of every solid and fluid of the human body. These proportions have been reduced to definite standards, a deviation from which affords evidence of disease. Thus, there being a fixed standard in a normal proportion of the elements of the blood, any deviation from it, as in anæmia, leucocythæmia, etc., indicates disease. So also the standard proportion of the urinary elements being known, any considerable change, either in quantity or quality of its parts, bears unmistakable evidence of disease. The invention of the microscope has provided increased facilities for detecting diseases by examination of the urine. By the aid of this wonderful instrument, we are enabled to discover with absolute certainty the various urinary deposits characteristic of different maladies; thus in Fig. 1, A represents in a general way the sediment of abnormal urine as seen under the microscope. In division B is represented oxalate of urea upon precipitation by oxalic acid. Nitrate of urea is represented in division C. A deficiency of urea in the urine, with albumen and casts present, is a most important guide in the diagnosis of Bright's disease. The average quantity of urea present during health is 21.57 parts in 1,000. The microscopic examination of the urine, notwithstanding the distaste, and even contempt, which many physicians manifest for such investigations, is pursued at the Invalids' Hotel and Surgical Institute, with inestimable benefit to our patients. It has revealed the existence of many serious affections, which, with all our other modes of investigation, we might have been unable to detect. It has also thrown light upon many obscure chronic diseases.
