$THE LANCET, March 3. 1894. ON I THE PHYSICS OF THE CIRCULATION. | S)elivered before the Royal College of Physicians at the\ Essaviination Hall, Victoria Embankment, on Feb. 27th, 1894. By PAUL M. QHAPMAN, M.D., F.R.C.P.Lond., PHYSICIAN TO THE HEaEFORD GENERAL INFIRMARY. LECTURE I. Mb. PBB3IDBNT AND FELLOWS,—Ifc has been my object, •ever since my observation was first directed by Dr. Bardon Sanderson to the consideration of the graphic representation of the heart's action, to endeavour to obtain a more accurate olinicaJ knowledge of the state of the whole circulation than ■is obtained by the ordinary methods of the physician. For this purpose I have studied the literature of the subject and the results published by physiological laboratories in England and on the Continent, at the same time endeavouring to carry on clinical observations of my own by methods which I shall describg in the course of these lectures. It would be impos- eible to treat the whole subject of the Physics of the Circulation in three short lectures, and some explana- ^;ion is due from me as to the selection of my title, for which I must ask your indulgence. The aim of these lectures is to commend as strongly as possible ■a more close and accurate observation of the state of the circulation in the sick than is now employed in clinical medicine. The cardiograph has practically never been used by physicians, while the sphygmograph ■has fallen into disuse. The indistinct and largely imaginative ase of the senses of hearing and touch has led to the disuse, .and in Englatd to the distrust, of accurate instrumental measurement in medicine in favour of the employment of what we like to call our own unaided observation. I believe that partly reluctance to take trouble and partly the sense that our own individuality, rather than great accuracy in diagnosis, is the main factor in creating what is 'known as a successful practice, have more to do with this feeling than we are ever likely co acknowledge to ourselves. Be this as it may, it is the conviction of others besides myself •that the employment of the cardiograph alone may give us definite proof of conditions otherwise not recognisable-^stiU more, that the combined use of the cardiograph with the sphygmograph may be the only means in certain cases of arriving at a definite diagnosis. It is especially for the latter ■method of observation that these lectures are intended to be some preparation, and this can only be done by entering somewhat largely into the subject of the physics of the circulation, which will be dealt with in a kind of summary of our present knowledge. Tlio graphic representation of the arterial pulse and its relation to the cardiographic tracing •can then, and then only, be properly discussed. It will be found, in the course of these lectures, more convenient to consider the cardiographic tracing first by itself separately$
