 which it contained presented almost the same appearance as 

 at first. Amongst these was found a minute whitish mass, 

 about a line in diameter, made up of very delicate mycelial 

 filaments, partly twisted around a cotton fibre. Near the 

 centre of the mass was a large, brown, flagon-like body, 

 about 3^y" in diameter, from all parts of the surface of 

 which issued the mycelial filaments whose ramifications went 

 to constitute the rest of the mass. One or two smaller 

 growths were also found attached to some of the flakes, as 

 well as several distinct spore-like bodies of different sizes 

 mostly of a brownish colour, and having thick walls with 

 granular contents. A group of fine spore-like bodies was 

 also found ; these being larger {^\-^' in diameter) and colour-

 and ammonic bichromate, whose periods of preparation and 

 examination were also similar, were similarly unproductive. 

 All four solutions had been prepared wdth distilled water 

 taken from the same bottle.

 also, there were, on certain portions of this fibre, plate-like 

 expansions, some of which were irregular in outline whilst
