CHAPTER XI.

On the motion of fermentation insofar as it is observed in the precipitation of bodies, page 81.

Precipitation occurs either in natural things or in the works of art, in the same place original: ibid.; referring to page 81. How cheese and butter are made from milk and its precipitated "flowers" original: floribus; referring to the cream or solid particles that separate from the liquid, pages 82, 83. The precipitation of blood and urine, in the same place. In artificial processes, precipitation follows dissolution, page 84. It is distinguished in various ways according to the diversity of the menstruum a solvent used to dissolve solids, the dissolved matter, and the added precipitant, in the same place. The precipitation of mineral solutions, pages 85, 86, 87. In these, either the pores of the solvent are constricted; or the particles of the dissolved substance increase in mass and weight, in the same place. The precipitation of the smallest particles, in which nothing settles but only the color, smell, or consistency of the liquid are altered, pages 88, 89.

CHAPTER XII.

On the motion of fermentation insofar as it is observed in the coagulation and freezing of bodies, page 90.

How the crystallization of salts is performed, page 92. The origin of the specific shapes of salts, page 93. On vitrification the process of turning a substance into glass, page 94. On the baking of bricks and pottery, page 95. The freezing of different kinds of salts, and the different kinds of products—precipitated and sublimated—produced from them, page 96. Artificial freezing, page 97.
