Note 144 — Chapter VI · THE PHYSIOLOGICAL THEORY OF FERMENTATION. (continued 2)

In this case the liquid was composed as follows:—a saturated solution of lactate of lime, at a temperature of 25° C. (77° F.) was prepared, containing for every 100 c.c. (3-½ fl. oz.) 25·65 grammes (394 grains) of the lactate, C6H5O5CaO [new notation, C6H10CaO6]. This solution was rendered very clear by the addition of one gramme of phosphate of ammonia and subsequent filtration. For a volume of 8 litres (14 pints) of this clear, saturated solution, we used [1 gramme = 15·43 grains]:—

Phosphate of ammonia 2 grammes.

Phosphate of potassium 1 grammes.

Phosphate of magnesium 1 grammes.

Sulphate of ammonia 0·5 gramme.
