Trichise. The cells are either not very long, and in that 

 case pointed at both ends and contain few spirals, by 

 means of which the walls of the cells are, as it were, 

 expanded ; or the cells are very long, divaricately rami- 

 fied, and intricately interlaced with each other. More-

 cells containing the spiral fibres, which require high mag- 

 nifying powers for their observation. 



On Lanosa Nivalis Frs. By Professor UNGER, of

Occurrence of Cysts, containing Filamentous Fungi, in 

 the Internal Ear of a Young Woman. By Professor

 Mucedo. 



The Report of the Swedish Academy of Sciences for 

 1844, contains an instance of AcJilya prolifera prpducing 

 the death of fish. My friend Lichten stein sent me a 

 small Cyprinus Alburnus, the mouth of which was en- 

 tirely closed by the growth of Acklya prolifera. Almost
