probably belonging to the same life-cycle, in which true spores were 

 produced ; the germination of these, which they observed, took place by 

 the emission of a short curved tube, giving the spore a "comma "-like 

 appearance ; the tube soon became spiral. (See Spirillum rosaceum, 

 Klein, p. 94.) 



97. B. sulfuratum, Warming (I.e., p. 6 of the Resume"). 

 Warming gives this name to a series of forms which 



he discovered on the coasts of Denmark, all of which he 

 considers to be connected by intermediate stages. He 

 includes under it Monas vinosa, Ehrenberg, M. erubescens, 

 Ehrenberg, M. Warmingit, Cohn, and Rhabdomonas rosea, 

 Cohn, as well as spiral forms. His M. gracilis, moreover, 

 seems to differ merely in being more slender than Rhabdo- 

 monas, and was met with only in fresh water. All these 

 are of a pale pink colour, and contain numerous sulphur 

 granules. It appears to be distinct from B. rubescens, 

 Lankester, in all its varieties. 



98. B. lactis, Lister (Quart. Jour. Micr. Sci., 1873, 



pp. 380-408). 



Includes coccus, bacterioid, bacillar, leptothrix, and 

 saccharomycetoid forms, motile and immotile, which the

 appeared spontaneously in milk kept in a dairy. The 

 long rods appear to be formed by segmentation of the lepto- 

 thrix threads, these subdivide into short rods, and these into
