had formed from the surface of the liquid to the bottom. Its 

 diameter was 15 mm., length 240 mm. or about 9.6 inches; this 

 "was in a single piece, but was broken in getting it out. Its ex- 

 treme lower portion was of somewhat looser consistence than 

 the parts above. To the naked eye this was seen to be distinctly 

 stratified throughout by an alternation of opaque and trans- 

 lucent layers varying from the thickness of writing-paper up to 

 one or two millimeters. 



The superincumbent vinegar was perfectly clear when first 

 seen, and contained only a very few cells of some species of Sac- 

 char 07ni/cetes similar to those next described. 



The turbid liquid contained numerous Saccliaromycetes cells, 

 some spherical and detached, others in pairs or groups of threes 

 when they were oblong, about twice as long as broad and at- 

 tached end to end. Some of these were budding; their granular 

 contents were well defined under a 0.1 inch water immersion 

 objective. There were also myriads of smaller, spherical 

 cells, mainly in rows or chains of from three to eight, many 

 of the latter number being observed. Some of these chains 

 were enwrapped in a transparent substance, apparently gela- 

 tinous; others were observed to be loosely connected, form- 

 ing colonies; many transparent masses of gelatinous material 

 contained numerous chains of these smaller spherical cells, 

 which appear from figures and description in Grove's " Bacteria 

 and Yeast Fungi " to be the Saccliaromycetes mycoderma, Eeess, 

 {Mycodernia cerevism, Desmazieres). Associated were swarms 

 of extremely minute microbes, their length about one half the 

 diameter of the smaller spherical cells, their diameter probably 

 about one-eighth their length, and in rapid vibratory mo- 

 tion. No other organisms were detected. The gelatinous cyl- 

 inder was tough in texture, requiring considerable force to pull 

 fragments from it, and could be lifted between the fingers with 

 only a slight compression of its periphery. Fragments taken 

 from near its top and from points one-half and three-fourths 

 the way down showed a nearly amorphous structure, which I 

 could at times imagine was irregularly cellular, but, if so, there 

 is no definite shape to the cells. A fragment from the extreme 

 base of the cylinder was, however, seen to be almost entirely
