of them are covered by the above description, and that there 

 has been no mortality due to the disease. 



We are of the opinion that of the cases occurring between July, 

 1912, and January 25, 1913, only one was smallpox or varioloid; 

 and that case undoubtedly contracted the infection in China, as 

 the disease developed a week after his departure from Hongkong 

 and two weeks after leaving Shanghai. The other cases we think 

 were not smallpox because: 



(1) The cases were uniformly mild, the lesions like those of chickenpox 

 rather than smallpox ; shotty induration, umbilication, and pustulation were 

 of rare occurrence. 



(2) Previous successful vaccination or previous smallpox did not influ- 

 ence the occurrence or severity of this disease. 



(3) Absence of both previous vaccination and previous smallpox did not 

 influence it. 



(4) Attempts (7 in number) to infect monkeys by inoculation with fresh 

 vesicle contents were uniformly unsuccessful. Had the disease been small- 

 pox most of the monkeys should have shown successful inoculations. 



As illustrating the absence of influence of both smallpox and 

 vaccinia on the occurrence of this disease, the following table 

 shows the facts in regard to 15 patients admitted from January 

 4 to January 29, 1913.

We are of the opinion that the disease in question is not small- 

 pox or varioloid and that it is, in all probability, chickenpox; 

 and that smallpox, except for an occasional imported case, is 

 nonexistent in Manila. If our opinion be correct, the facts sig- 

 nify a notable achievement in preventive medicine, and it is 

 unfortunate that the records do not show it forth.
