In women those figures are slightly less, while inchildren the area of the heart measures relatively more than inadults. Tf the median line is taken as the landmark from whichto measure, Ilondcohrs figures must be increased by 1 to centi-metre, which, according to Ebstein, is half the Midth of the ster-num. Consecjuently it is found that Vierordts and Hornkolilsestimates are not so much at variance as they at first appear. Three methods of percussion are in use, and mentioned in the.

I do not propose to discuss the advan-tages or disadvantages of employing a pleximeter and hammer,but merely to express my very positive preference for the use ofthe fingers, for the reason that thereby one is enabled to obtainvaluable information from the sense of resistance. In ascertaining the area of absolute dulness light strokes areessential, while the reverse is the case as regards deep-seated dul-ness. Moreover, in outlining the area of relative dulness thepleximeter finger should be pressed firmly against the chest-vi^all,to exclude so far as possible the vibrations of the bony is the ahgeddmpfte percussion of the
