About this book

Yeast is a piece by Thomas Henry Huxley whose speaker says he has selected to-night the particular subject of Yeast for two reasons. The speaker gives as a first reason that yeast is one of the simplest and the most familiar objects with which we are acquainted. The text describes a liquid that begins to be turbid, with bubbles making their appearance in it and a sort of dirty-looking yellowish foam or scum collecting at the surface.

The speaker says the liquid has become completely altered, with a peculiar smell and the property of intoxicating the person who drinks it. The speaker believes that 99 per cent. at least of the sugar can now be accounted for, split up into four things, carbonic acid, alcohol, succinic acid, and glycerine. The speaker discusses vaccination, saying you may vaccinate a child as much as you like with the fluid parts, but no effect takes place.
