A turnip infusion rendered very faintly alkaline by liquor potassse. The flask was opened after nine weeks, when the vacuum was found to be partially preserved. The fluid was still of the same light brown colour as when it was taken from the digester. Its reaction was now decidedly acid, though the odour was slightly sour and not foetid. There was a small quantity of granular scum on some parts of the surface, and a distinct brownish flocculent sediment, but the bulk of the fluid was tolerably clear. On microscopical examination of the deposit, a number of minute Torula-celh were found, both singly and in groups. They varied from the minutest specks up to bodies j-oVo" in breadth, and were mostly with-. FIG. 32. Various kinds of Torulae. from a neutralized Infusion of Turnip. ( X 600.) out nuclei or vacuoles.
