| Title | Paper, 'The action of gravity upon Bacterium Zopfii' by Rubert William Boyce and A Ernest Evans |
| Creator | Evans; A Ernest (fl 1893) |
| Date | 1893 |
| Description | The authors write: 'In May, 1892, Mr Walter Spencer handed over to us the body of a cat in which he had discovered a double 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 regular growth of delicate white filaments. Re-inoculation proved the presence of more than one micro-organism, hut we soon succeeded in isolating one which did not liquefy the gelatine, and which presented the exceedingly characteristic feather-like appearance well known to belong to Bacterium Zopfii.'
Annotations in pencil and ink. Includes six plates of microphotography.
