Note 139 — Chapter VI · THE PHYSIOLOGICAL THEORY OF FERMENTATION. (continued 2)
Frank Faulkner translation
We treated the whole deposit with dilute hydrochloric acid, which dissolved the carbonate of lime, and the insoluble phosphates of calcium and magnesium; afterwards filtering the liquid through a weighed filter paper. Dried at 100° C. (212° F.), the weight of organic matter thus obtained was 0·54 gramme (8·3 grains), which was rather more than 1/200th of the weight of fermentable matter.
