ult liquefies the gelatine very quickly, sinking to the bottom 
a red mass, forms a ring at the surface, and decomposes t 
liquefied gelatin, generating a foul odor, whereas no. 3 neither 
liquefies gelatin quickly nor gives off a foul odor in any sta 
of its culture. The indications are that no. 3 is a new species rt 
Mycoderma.
