In other establishments, instead of using hydraulic presses, juice is extracted from the pulp in centrifugal machines in which large quantities of water are used. In others the " process of diffusion," so called, by which the beets are cut into thin slices, and the saccharine matter exhausted by steeping them in water in a series of vessels.

In my judgment, however, incomparably the best process is the system of " double carbonitation," so called, of Perier and Possoz. This method reduces the quantity of bone black required to a very small amount, allowin...
