Following is a similar tabulated statement for the years 

 1909, 1910, 1911 and 1912 to the date of writing, 

 August 19. 



The result of the examination of small butterfish in the 

 year 1911 appears to be exceptional. In other years I have 

 found the small butterfish to be but sparingly infected. 



On September 15, 1911, I examined a lot of 223 butter- 

 fish ranging in length from 68 to 100 millimeters, and made 

 the following record of cysts found : Very numerous, 63 ; 

 numerous, 54 ; many, 62 ; few, 24 ; very few 19. 



It is an interesting fact that the butterfish in the Woods 

 Hole region that are taken late in the season show a higher 

 percentage of infection than is shown by those taken earlier 

 in the season.
