in fresh specimens of this jelly under powers of 600 or 700 



diameters, when the most characteristic structures are those 



to which I have applied the term mycelia, and which, as stated 



ahove, were considered to be capillaries by some savants to 



whom I had shown the specimens. At a in figures 30 and 31 



are seen these filaments in various forms ; they appear to consist 



of an extremely delicate limiting membrane (appearing better 



defined in filaments of medium size than in the larger ones) of 



highly refractive semi-fluid contents, and, at intervals, masses of 



spores of a still higher refractive power than the fluid in which 



they lie.

a a. Filaments, 

 c c. Free spores. 



h b. The spore masse.s in the filaments. 

 d. Micrococci or spores. 



These spore masses are seen at h in both figures, and at c there 

 are a few free spores outside the filaments. Figure 31 shows the 

 appearance I have most commonly observed, figure 30 represents 

 a less common appearance, where they resemble berries upon 

 short stalks. 



As arguments against these mycelia or filaments being 

 capillaries, I would point to their peculiarity of branching, the
