Take for example the two instruments uporwhich we place today our chief reliance for obtaininoordinary routine|clinical data—the thermometer andthe watch. Although the former instrument datesback to the time of Galileo, and was used by him asa means of estimating body temperature, the neces-sity of thermometric observations in disease had nowidespread clinical recognition until after the publi-cation of Wunderlichs classical monograph in 1868.Today one wishes to know, not as in pre-Boerhaav-ian times solely by manual palpation that there is amore or less evident pyrexia, but the degrees orfractions of degrees of variation, which our instru-ment of precision alone can supply.

At the present time, largely owing to theconvenience of our timepieces, pulse-rate is com-monly recorded alongside of the temperature andperhaps of the respiration on our clinical charts, tothe utter neglect of a numerical record of that vascu-lar quality which in many conditions is incompar-ably of greater clinical consequence, namely, arterialtension. The familiar query is raised. Are we not surfeitedwith instruments of accuracy in clinic
