adequate attention.

      De Haen's successor in Vienna, Maximilian Stoll, treated Auenbrugger's work very differently from his predecessors, and was the first to introduce it practically into clinical medical training. Stoll did not hesitate in his clinic, on the strength of what was discovered by means of percussion, to attempt the evacuation of fluid from the pleural cavity on a number of occasions. It can be easily understood that with their lack of knowledge of the necessity for thorough cleanliness in the surgical sense, such an operation might readily be followed by discouragingly fatal results. This actually happened in Stoll's own experience. He does not, however, seem to have abandoned his practice of tapping the chest because of this. He insisted to his students that Auenbrugger more than anyone else had experience in removing fluid, and especially purulent collections, from the chest, and he recommended the practice to them. He added that medicine owed as much to Auenbrugger for his rational method of treating effusions into the pleural cavity, whether of pus or serum, as for his diagnostic sign by which the presence of the fluid could surely be recognized.

      Some of Stoll's pupils took up the work of commending Auenbrugger's method, and a little book written by one of them, Eyerel, came into the hands of the distinguished French physician, Corvisart. Eyerel did not hesitate to say, in his treatise on empyema, that the practice of percussion of the thorax, a diagnostic method introduced by the very distinguished Vienna physician, Auenbrugger, had been of great help to them in the study of this disease.

      Once the great French professor of medicine, Corvisart, took it up, the new method of diagnosis was destined to have an immediate and world-wide vogue. Corvisart was not only a power in medicine because of his faculty of observation and his thorough appreciation of the work of others, but he was the court physician of the first Napoleon, and this gave any ideas that he favored many adventitious chances for publicity. Napoleon's well-known faculty for selecting men for special positions whose genius was calculated to be of service to him was never less at fault than when he violated most of the court medical traditions in Paris and chose Corvisart for the imperial physician. Corvisart's selection was the result of Napoleon's appreciation of his new method of diagnosis, namely, that of percussion, in chest diseases.

      The Emperor himself was suffering from a persistent cold and was told that Corvisart, instead of following the traditional method of feeling the pulse, looking very wisely at the tongue and then gazing learnedly into space, conducted an actual examination of the chest and sounded it carefully all over, in order to determine where abnormal conditions might exist. This struck Napoleon as a very practical and possibly valuable feature of diagnosis. Accordingly Corvisart was summoned to give his professional opinion. After the consultation he was made the Emperor's private physician. When Corvisart took up the subject of percussion of the chest, it was practically unknown in Europe outside of Vienna. Even in the city of its origin, as we have seen, it was not well appreciated. Auenbrugger's little book had fallen into oblivion. Corvisart obtained his hint as to the possible value of percussion from Stoll's and Eyerel's appreciative remarks with regard to it. The Frenchman used the method to some extent and, realizing its value, resolved to call the attention of his countrymen and the medical world to this very helpful aid in diagnosis. It was at this time that he came upon Auenbrugger's original monograph. Instead then of writing himself on the subject, he translated Auenbrugger's little book into French and made a commentary on it.

      Corvisart was Laennec's patron in medicine, his favorite teacher, and the man to whom the great French physician owed much of his early inspiration. It is no little merit in Corvisart's career thus to have been the connecting link between the men who did most for the practical science of medicine, and especially for the important but obscure chapter of diseases of the chest. He did not attempt at all to claim for himself any of the merit that he felt should rightfully go to Auenbrugger, and while his own observations and writings established percussion upon a firm basis and extended its knowledge, he shares the immortality of his discoverer, and comes down to us in medical history as an example of the reward of having rendered faithfully what was due, where it was due. It has been the custom to praise Corvisart for his justice toward Auenbrugger. Mere justice seems scarcely a worthy reason for praise of a great man, yet the history of medicine is so full of failures on the part of subsequent observers to acknowledge priority of discovery, that perhaps the praise does not seem quite as futile as it otherwise would.

      It is not surprising then that Corvisart's pupil Laennec should have appreciated very thoroughly the value of Auenbrugger's discovery. In the preface of his book on Mediate Auscultation, Laennec bewails the fact that men are generally neglectful of discoveries made in their own time, and fail to give them the attention they deserve. He attributes this neglect rather to the well-known carelessness of men than to any deliberate failure to recognize the merit of contemporary work. He says:

      "Lack of attention is an extremely common failing of all men. What it takes years and hard labor to acquire, is not infrequently passed over without notice. Auenbrugger's method, published some fifty years ago, though capable of being learned in a few days, and without difficulty, and of being put into practice without the use of any instruments, although snatched from oblivion by my illustrious preceptor, Professor Corvisart, and made clearer than it had been left even by the author himself, is not as yet in ordinary use among physicians. Even the wonderful invention of the illustrious Jenner, though received with so much praise, and with regard to whose efficaciousness numberless confirmatory observations have been made, is already somewhat less prominent in the minds of men than it should be, or at least it would be, only for the fact that the governments of many countries, provinces and cities, the foresight of the clergy, of the authorities of all kinds, and the advice of the best physicians have exerted all their influence to keep it at public expense constantly in practice."

      After about ten years of service at the Spanish military hospital, Auenbrugger resigned his position there and took up private practice. In this he was eminently successful, being, as might be expected, especially in demand for cases involving affections of the thorax. His practice appears to have been to a great extent among the better class of people, but he seems never to have neglected the poorer patients whom he had come to know during his hospital experience. There are traditions in Vienna of his unfailing willingness to assist the poor and even to put himself to considerable inconvenience in order to be of service to them.

      Tradition tells that he was very conscientious in the pursuit of his vocation as a physician, and among the family relics there is preserved a small lantern which he kept always by his bedside, to light him on his visits to the sick when called out at night. It must not be forgotten that city streets were not regularly lighted at the end of the eighteenth century, and night calls even in city work must have been a source of great annoyance and discomfort. There is a family tradition, too, that the night bell at his house was connected directly with Auenbrugger's room, so that the others of the household might not be disturbed when night callers came for him. Every tradition points to him as a man among men in his unselfish readiness to save others trouble, and do all the good in his power.

      Auenbrugger was, according to well-grounded traditions, especially admirable in his relations toward other members of the medical profession. This may not seem a very significant sign of amiability to those outside the profession, but it is well recognized that even great physicians have not always been known to get on well with brother practitioners. Auenbrugger has, besides, the pleasant reputation of having been of great material assistance to a number of needy medical students during the time of their university careers, and to have frequently lent a helping hand to young practitioners in the city, who probably found it quite as discouraging, beginning practice in those days, as any of their young confreres of this generation find it at the present time.

      To physicians and medical students when ill, Auenbrugger was almost unceasing in attention. Two or three physicians of the generation immediately after his attributed to his unselfish care and devotion to them their recovery from what would otherwise have been mortal illnesses. In this way Auenbrugger seems to have been a man whom everyone who came to know him, even slightly, learned to love and respect. His relations to his family and relatives were always of the most happy, kind character, and family traditions show that his fatherly care was befittingly returned to him in his old age. The number of his friends was very great, and he counted among them some of the most distinguished inhabitants of the Austrian capital.
