Nothing like conjugation, or any other form of sexual genera-tion, has yet been witnessed in any Bacteria ; and until such shallhave been discovered, no confidence can be felt that we know theentire life-history of any one When these facts are allowed.

This action is altogether analogous to that of the yeast-plant in producing saccharine ferment
