ment in scurvy is an involvement of the vagus and that it is 

 hard to understand the predisposition of the right heart to 

 enlarge unless this is associated with a disturbance of the cir- 

 culation in the lungs. He mentions also the frequent occur- 

 rence of pneumonia in the course of scurvy. 



In this series bronchopneumonia was diagnosed as terminal 

 and slight in two cases of infantile beriberi (autopsies 1616 

 and 1618), and description of the lungs is as follows: (4) 



Scattered over the surface are a few darker colored areas which are 

 slightly firmer on section, are not elevated above the surface, do not appear 

 granular, and on slight pressure considerable edema fluid can be expressed. 



BRONCHOPNEUMONIA 



Disease of the respiratory tract is second in rank in the 

 causes of infant mortality in Manila and first in other big cities 

 (Albert). (2) 



This vulnerability or weakness is, according to Holt, (27) due 

 to its structure, for the trachea of the young is relatively larger, 

 the bronchi are more numerous and occupy greater space, 

 the air sacs are much smaller, and the interstitial tissue is more 

 abundant ; besides that, the capacity of the thorax is encroached 

 upon by the high position of the diaphragm, the large size of the 

 thymus gland, and the frequent distention of the stomach and 

 intestines. 



The seasonal and age incidences in this series, which comprises 

 180 cases, or 18 per cent, without including tuberculosis, is as 

 follows :
