PATHOLOGY OF PULMONARY CONSUMPTION. 285 a most significant fact relative to the genesis of pulmonarydisease through the instrumentality of the nervous system,for, as has previously been shown, such narrowing andocclusion are common characteristics of chronic catarrhaland interstitial pneumonia in man. On this subject Hamil-ton* says: In many of the smaller arteries, however, thereis a lesion, which I have always found associated withchronic interstitial pneumonia, and which, perhaps, mightaccount for many anomalous appearances seen in them. Itis that extremely important disease of the inner coat of theartery, called arteritis obliterans by Heubner and Fried-lander, and which is referred to by the latter as ensuing in.

It is of so frequent occurrence and gen-erally so widely spread that I cannot help believing that itplays a most important role in bronchitis whenever there isany consecutive interstitial pneumonia present. In Fig. 26is seen the thickened intima of one of the branches of thepulmonary artery. Professor Hamilton further states that as a result of thisobliteration two changes are conspicuous, viz., caseation andsoftening of the pulmonary tracts supplied by the affected* Op. cit., p. 76. . 286 DISEASES OF THE LUNGS. vessels, and dilatation of the capillaries in the , in discussing the influence of a
