With regard to the phenomena exhibited b}" the remaining cases in 
I which symptoms were noticed, there is no wa}" of demonstrating 
j whether the presence of Hymenolepis nana was anything more than 
j an attendant circumstance, indeed, in man}^ of the cases it is quite 
j apparent that there could have been no causal relation between the 
! presence of the tapeworm and the S 3 ^mptoms, while in others, in which 
! such a connection seems more or less probable, the evidence is too 
incomplete to warrant such an assumption, and in a number of these 
latter it is furthermore questionable whether the other parasites pres- 
ent might not be of equal or greater importance in the etiology of 
S}miptoms. Following is a list of svmptoms, with their frequency,
