Hofer (6) admits the lack of parallelism between the invasion of the 
kidney and the superficial lesions. 
In the case of the plaice showing a superficial condition undoubtedly 
similar to the Epithelioma papulosum of the Carp, no trace of any 
sporozoon could be found, either in the lesions or in the tissues. A 
most careful examination was made, and portions of every organ were 
sectionised, but with absolutely negative results.
