staining had been tried, to find one with a single flagelluni. 



The next examination, a day later, offered for view quite a 

 different set of objects, or rather similar objects in a different 

 stage. The spirilla were now found in numerous small and large 

 colonies, varying from five or six organisms to more than a 

 hundred gathered together. Lying amongst them were, here and 

 there, seen the small circular or oval bodies which I regard as 

 spores — some free and some apparently attached to one end of 

 a few of the felted commas. These immobile organisms, though 

 not measured, appeared a trifle larger than the free ones previ-

ously described. In some of the colonies, at the border, a few 

 could be seen separated from the general collection, and in one 

 or two cases with a sifigle flagellum. Whether these had divided 

 off from others, and so produced the flagellum at the point of 

 separation by drawing out the inner plasm, or any living plastic 

 membrane, or \\hether they had grown with the growth of the 

 organism, I will not venture to decide. As I have several times 

 seen, in the full-grown spirillum with the joints adhering, project- 

 ing from the points where separation into commas would take
