Physical Signs.—In some instances the hypertrophy of the unaffectedlung is extraordinarily great. This may be apparent on inspection sound side is seen to be much larger, and the range of the expansilemoAements unusually large. This is more apparent because of theabsent or very restricted motion of the opposite or diseased side. Further-more, the latter side is not uncommonly retracted. If the right lungis h^-pertrophied, the apex beat of the heart will be seen to have beendisplaced to the left, partly because of the mediastinal contents being.

Compensatory emphysema of leftlung Tvhich extends to the right border of the sternum. crowded over to the left by the enlarged lung, and partly because it ispulled over by fibroid changes on the left side. In some instances withright-sided hypertrophy and left-sided disease, the heart is drawn up-ward, the apex beat being most marked in the fourth or even the thirdinterspace. If the left lung is hypertrophied and the right diseased,the heart is displaced to the right in exactly the same way. In bothinstances the extent of the hypertrophy on the one hand, and the diseaseon the other will determine how great the displacement will be. It isnot uncommon to see the heart parth^ pushed and parth pulled so far tothe right as to resemble a case of dextro-cardia. The displacement of the heart toward the diseased side instead ofaway from it, distinguishes this condition at o
