The first of these papers contains an historical introduction to the study of 
Infusoria, a short exposition and risimiS of their structure, and descriptions 
of forty-two known species. In No. 2 twenty-eight marine species occurring 
at Warberg are described, of which eleven are considered new by the author. 
In No. 3 a list of thirty Infusoria is given as observed in the sea at Wisby,

on the integumentary, digestive, and reproductive systems of 
Epistylis flavicans, Ehr. He finds below the outer skin of most

considers to be true trichocysts, and thinks that the staff-shaped 
bodies described as such in other Infusoria are neither tricho- 
cysts nor touch-corpuscles, but skeletal organs. Greeflf has also 
observed in the same species an apparent distinction of sex, 
hair-shaped bodies like spermatozoa becoming developed in the
