214 OILMAN. 



Unresolved pneumonia was found in one case, with typical fibroid 

 induration of the entire lobe. The patient died of an acute beriberi. 



The following complications of pneumonia were presented: endo- 

 carditis in 2 cases, pericarditis in 1, nephritis in 5, and pleurisy in 

 all but 2 of the early cases. 



Primary broncho-pneumonia occurred in 3 of the 15 cases of this 

 disease, all of these being in children of 3 years of age. Seven cases 

 of the secondary form of disease had developed during the course of 

 infectious diseases and 5 were in old, emaciated subjects and were of 

 the aspiration or deglutition type. 



Other pulmonary lesions were encountered in the routine examination 

 of the organs from autopsies, as follows: oedema and congestion in 

 27 cases, infarction in 5, and emphysema in but 2 cases. 



HEART AND BLOOD VESSELS. 



Death could be ascribed to chronic cardiac change associated with 

 arterial degeneration in but 6 of the 100 cases, but it is also true that 

 a normal heart was the exception, some change in or within the walls 

 occurring in 62 instances. In 4 of the above-mentioned 6 cases, an 

 acute dilatation of an hj^pertrophied organ was found associated with 

 more or less rigid curling of the mitral valves and damage to the lining 

 of the aorta; in the other two cases, there was a marked grade of fatty 

 infiltration, the muscle fibers being completely occupied with rows of 

 small globules. Stenosis was observed but once, the mitral orifice being 

 affected. 



The common type of heart found in the majority of instances was a 

 flabby, relaxed, more or less dilated organ, showing practically no at- 

 tempt at hypertrophy. The heart muscle in these cases was pale brown- 

 ish or yellowish-brown in color, possessed a turbid appearance and was 

 very soft. Histologically, the fibers showed varying grades of granular 

 degeneration. Fragmentation was frequently observed and in the greater 

 number of the specimens studied very little new formation of scar tissue 

 had occurred. A condition of relative insufficiency was found in 26 

 cases. 



Acute disease of the endocardium followed an operation for imper- 

 forate anus in a child of 5 days, and occurred as a complication of pneu- 

 monia twice. In each of the cases there was a vegetative inflammation 

 of the mitral valves. 



Acute myocarditis was present in five instances, four in cases of beri- 

 beri and one in acute yellow atrophy of the liver. Acute pericarditis 

 occurred once in a child of 1 year and S months, who died of broncho- 

 pneumonia. 



Arterial changes were the exception in this series of examinations. 

 The vessels in only 6 of the 100 bodies showed thickening and loss of 

 elasticity and of the 6, but 2 evidenced a marked grade of degeneration
