In Naples, as we are told by Dr. James Johnson and other writers, this disease is endemic, and is very reasonably attributed by them to the chilling tramontanes, which are constantly surprising the inhabitants enervated by sultry skies and siroccos. It is possible that the foreign particles abounding in the air of Bristol, may have something to do with the frequency of bronchitis. We seldom find this disease fatal in its acute form, when judiciously treated, but it is very prone to pass into the chronic form, and then becomes extremely intractable.
Of the chronic diseases of the lungs, phthisis maintains its predominance here as elsewhere. Sometimes it supervenes on acute inflammation of the bronchial membrane, or of the pulmonary tissue, but far more frequently it takes its origin solely from the peculiar structural degeneration in which its essence consists.
