ANALYSIS OF THE TWENTY CASES REPORTED AND SUM- 

 MARY OF PATHOLOGICAL FINDINGS. 



An analysis of the twenty cases of plague reported above shows 

 that the total figure is made up of: 



Cases. 



Group I. Primary uncomplicated bubonic plague 11 



II. Primary bubonic plague with secondary plague septico- 

 pyemia 4 



III. Primary bubonic plague with secondary plague pneumonia.. 1 



IV. Primary uncomplicated plague pneumonia 2 



V. Primary pneumonia with secondary septieo-pyemia 1 



VI. Primary plague septicaemia 1 



Sixteen of these twenty cases were of the bubonic type, three of 

 the pneumonic, and one of the septic type. Of the bubonic cases 

 there were: 



Cases. 



Inguinal buboes 11 



Axillary buboes I 



Cervical buboes 4 



The great preponderance of the bubonic type of plague cases is 

 fully in accord with the observations made by the Indian Plague 

 Commission on a very large amount of material; and the pre- 

 ponderance of inguinal buboes over cervical and axillary ones 

 is likewise the rule among races and in localities where the people 

 in general are barefooted. Of the cases of cervical buboes there 

 were three found in children, among whom their occurrence is the 

 most common, and one in a man of 63. Twelve of the 20 cases 

 occurred in native Filipinos and 8 in Chinese, 15 in males, and 5 

 in females. The great preponderance of males over females is 

 partly due to the fact that in one part of the affected population — 

 namely, the Chinese — the greater proportion consists of males. 

 However, even in India the number of cases in males greatly 

 exceeds that in females, though not in the proportion of three 

 to one. As to age, the cases reported range from 5 to 63 years, which 

 is in accord with the general experience gained on a large scale. 

 The majority of our twenty cases — viz, thirteen — occurred between 

 the ages of 20' and 40. Almost all of tbe plague victims came 

 from the lowest walks of life of the native and Chinese population. 

 One of the cases was that of a Chinese shopkeeper or merchant.
