Table II of the Manila cases shows the .preponderance of lesions on 

 the legs, as is the case in Table I, and also demonstrates that the number 

 and variety of lesions in the Manila cases was much less than in those 

 from Catbalogan. Their essential characters are the same. 



The spirochsetse which were seen present some interesting features. 

 The organisms were found in five of the thirty-four cases (about 15 per 

 cent). There were several varieties which may be divided into three 

 classes.
