fungus may result 5 or else into Bacteria^ which also 

 may develop into segmented filaments^ and thence 

 into distinct Fungi of a different type. These various 

 kinds of Fungi^ thus resulting from the development 

 of mere micrococci (or plastide-particles), are supposed 

 by Hallier to be capable of reproducing micrococci in 

 the manner already indicated by a breaking-up and 

 individualisation of the protoplasmic contents of cer- 

 tain reproductive cells^. Thus he claims to have shown 

 that such particles^ and Bacteria^ are merely the ultimate 

 reproductive elements of Fungi ; and he also tries to 

 show that they are the active infective agents in the 



establishment of cholera and 

 diseases 2.

 It will be seen on p. 245 of this ' Report' that Dr. Sanderson proposes to 

 include micrococci, arthrococci, other forms of Bacteria, and Bacteridia, 

 under the single designation * microzymes.* This, however, we consider for 

 many reasons undesirable. * Microzyme' seems to be too theoretical and 

 specific as a name for a simple particle of plasma, which may have nothing 

 to do with fermentation ; and we think that such rudimentary particles 

 ought to be distinguished by name from those which have assumed 

 some developed form. For this latter reason, therefore, we consider 

 Nageli's term, * Schitzomycefes,' even still more objectionable, since 

 according to De Bary, who adopts it, we are to include under this 

 designation ' fonns of extreme minuteness, as yet insufficiently known as 

 regards their organization, which are represented by the generic names, 

 Vibrio, Bacterium, Zooglcea (Cohn), Nosema (Nageli), Sarcina, &c.'

These claims and views have been carefully considered by Dr. 

 ■Burdon Sanderson, who says, in the before-mentioned Report, ' If it is 

 true that our common cereals are infected with an endophyte which 

 requires only certain very easily combined conditions of soil and tempe-
