Though introduced with success from Santo Domingo about the middle of the T 8th century, the sugar industry practically dates from 1796, when Etienne Bore first succeeded in crystallizing and clarifying the syrup. Steam motive power was first introduced on the plantations in 1822.
Many electrolytic methods have been proposed for the purification of sugar; in some of them soluble anodes are used for a few minutes in weak alkaline solutions, so that the caustic alkali from the cathode reaction may precipitate chemically the hydroxide of the anode metal dissolved in the liquid, the precipitate carrying with it mechanically some of the impurities present, and thus clarifying the solution.
The first step in clarifying the situation is to come to a full realization that the medieval Church was essentially an international state, and that the character of the Protestant secession from it was largely determined by this fact.
The blood is converted into clarifying material, the entrails are used for sausage coverings, the hoofs and small bones furnish the raw material for the manufacture of glue, the large bones are carved into knife handles, and the horns into combs, the fats are made to yield butterine, lard and soap, and the hides and hair are used in the manufacture of mattresses and felts.
The Catholic delegates, moreover, discovered a powerful auxiliary when Lainez, the general of the Jesuit order, which had been admitted into France a short time previously, entered the debate; and the acrimony with which he opposed the Protestants was of material service in clarifying the situation.
