112 VIGNETTES FROM INVISIBLE LIFE. 



We conclude this description in the words of 

 Joblot, one of the earliest observers of the seven- 

 teenth century, who, in describing this creature, 

 says : " Surely, this is a fish the most extraordinary 

 that one may see." 



NOTE. Actinophrys sol and Actinophrys eichornii (or, as it is 

 now named, Actinosphcerium eichornii), being so much alike in 

 everything almost, except size, the one description applies to the two 

 forms.
