A new method for the analysis of saccharose and raffinose, when in the presence of inverted sugar, is said to give accurate results.  The process consists in adding sulphate of copper and lime to hot molasses, so that the oxide of copper is changed to a protoxide, and the invert sugar becomes water and carbonic acid.  The whole is neutralized with phosphoric acid.  There follow a great number of precipitates; the exact volume of liquid in which these are found is determined after two polariscopic observations.

It has been constantly noticed that samples of carbonatated juice vary in composition with the part of tank from which they are taken.  If some arrangement could be made assuring a thorough mixing during the passage of carbonic acid, results would be more satisfactory than they now are.  If gas could be distributed in every part of the tank, the lime combination could be made perfect.

Notwithstanding the new law regulating quantity of sugar to be used in wines, ciders, etc., there has been, during 1890, an increase of nearly 13,000 tons, as compared with 1889.  Consumption of sugar for these special industries was 33,000 tons; alcohol thus added to wine was about 71,000,000 gallons.

Beets cultivated without extra fertilizers, and that are regular in shape and in good condition, without bruises, are the ones which give the best results in silos.  It is recommended to construct silos of two types; one which is to be opened before first frost, the other where beets remain for several months and are protected against excessive cold.  Great care should be taken that a thorough ventilation be given in the first mentioned type.  In the other, more substantial silos, ventilation must be watched, and all communication with the exterior closed as soon as the temperature falls to or near freezing.

During the last campaign many manufacturers experienced great difficulty in keeping the blades of slicers sufficiently sharp to work frozen beets.  Sharpening of blades is an operation attended to by special hands at the factory; and under ordinary circumstances there need be no difficulty.  However, it is now proposed to have central stations that will make a specialty of blade sharpening.  Under these circumstances manufacturers located in certain districts need give the matter no further thought, let the coming winter be as severe as it may.

Some success has been obtained by the use of sulphurous acid in vacuum pans.  Great care is required; the operation cannot be done by an ordinary workman.  It is claimed that graining thereby is more rapid and better than is now possible.  Chemists agree that the operation is more effectual by bringing sulphurous acid in contact with sirups rather than juices; it is in the sirups that the coloring pigments are found.  Sulphurous acid is run into the pan until the sirups cover the second coil.  In all cases the work must be done at a low temperature.
