acetous fermentation commences in seven or eight days, which is a sign that the acrid poisonous principle is dissipated: the pulpy, sour, and fibrous mass is then boiled and eaten; its nutriment being the starch, which exists in small quantities, and which they have not the skill to separate by grating and washing.

It is then very pleasant and refreshing, but in a few hours after sunrise a great charts takes place, and the rapidity of the transition from the vinous to the acetous fermentation is so great that by midday it resembles a poor and rather acid cider.

Hence spontaneous fermentation, vinous, acetous, and putrefactive, is the natural decomposition of animal and vegetable matters, to which a certain degree of fluidity is necessary; for where vegetable and animal substances are dry, as sugar and glue for instance, and are kept so, no fermentation of any kind succeeds.
