In May, 1892, Mr. Walter Spencer handed over to us the body of 

 a cat in which he had discovered a donble otitis media. Some of the 

 pus was immediately inoculated upon gelatine, and two days later it 

 was seen that the gelatine along the streak had liquefied, whilst the 

 rest of the surface of the non-liquefied gelatine was covered by a

 typical ones are reproduced, namely, figs. 10, 12, 14, 23, 28. It has been thought 

 better, however, to preserve the original numeration in the text, as the original 

 photographs can be consulted if necessary.
