Note 140 — Chapter VI · THE PHYSIOLOGICAL THEORY OF FERMENTATION. (continued 2)
Frank Faulkner translation
Should the solution of lactate of lime be turbid, it may be clarified by filtration, after previously adding a small quantity of phosphate of ammonia, which throws down phosphate of lime. It is only after this process of clarification and filtration that the phosphates of the formula are added. The solution soon becomes turbid, if left in contact with air, in consequence of the spontaneous formation of bacteria.
