74 DEATH OF HORSES FROM OATS AFFECTED WITH FUNGI. 
distilled water, well shaken, and strained through calico. 
The strained liquid was afterwards passed through paper. 
By this means we obtained a brownish mud-like substance 
which remained upon the filter, and a clear transparent 
fluid which passed through the filter. On allowing the pre¬ 
cipitate to remain in the laboratory at a temperature between 
60° and 70° Fahr., it soon assumed a mould-like appear¬ 
ance superficially. This mould-like substance when magni¬ 
fied, exhibited a vegetable filamentous structure, the fila¬ 
ments interlacing one another in a most beautiful manner, 
and similar to, if not identical with the substance produced 
during the germination of the bad oats, and which caused 
them to mat together. 
The clear liquid which passed through the filtering paper, 
after standing for a few days, developed a large quantity of a 
grayish insoluble substance, a portion of which fell to the 
bottom of the vessel, and another portion floated upon the 
surface of the fluid, and exhibited to the naked eye very 
marked “mouldy ” or fungoid characters. Fig. V shows

upon the surface of the fluid. Its structure, as well as its
