I am, moreover, well assured from lono- and careful observation, that chronic bronchitis is sometimes the direct consequence of some consti- tutional vice, apart from exposure to any external exciting cause. In confirmation of this opinion, I may remind you that bronchitis, although certainly far more prevalent in the colder season of the year, is by no means peculiar to it; and in some cases, even, has a definite tendency to recur periodically in summer, instead of in winter, and usually, on such periodical recurrence, to be associated with some well-marked constitutional disorder. I have already alluded to the intimate relations between chronic bronchitis and various other ail- ments, local or constitutional. These relations may be those either of cause or of consequence: as when, on the one hand, bronchitis produces some secondary lesion either of the lungs or heart, or some more remote sequence, such as disease of the liver or kidneys ; or as when, on the other hand, bronchitis is itself the secondary result of some constitutional vice, such as gout or sj'philis, or of soane local affection, such as cardiac or renal disease. Bronchitis may thus be either a primary or a secondary affection. Primary, when it is the mere result of exposure to cold or wet, or when the irritation excited by the inhalation of dust develops the disease. Secondary, when the bronchial affection arises out of some constitutional vice, or some other
