Страница 7 - Report on the culture of the sugar beet and the manufacture of sugar therefrom in France and the United States.
Страница 42 - This fat will not usually be clear; this however, will make no difference in the result, as the subsequent treatment will clarify it. As soon as the bottles have been sufficiently whirled, they should be filled to the neck with hot water. This is most conveniently done by placing a vessel containing boiling water above the machine, and by means of a syphon, made from a small rubber tube with a glass tip, run the water directly into the bottles without removing them from the wheel.
Страница 72 - Vilmorin is manufactured in connection with other varieties it is the custom to reserve this for the end of the season and to work up the less reliable beets at an earlier date. It is also said to resist better than any other variety the unfavorable influence of certain characters of soil and of certain manures. In black soils, rich in organic matter, it will give great industrial results, while most other varieties of beets become watery or saline in excess.
Страница 222 - If the mixture froth badly, a small piece of paraffin may be added to prevent it. The heat is then raised until the acid boils briskly. No further attention is required till the contents of the flask have become a clear liquid, which is colorless, or at least has only a very pale straw color.
Страница 42 - An even number of bottles should be whirled at the same time, and they should be placed in the wheel in pairs opposite to each other, so that the equilibrium of the apparatus will not be disturbed. When all of the test bottles are placed in the apparatus, the cover is placed upon the...

If the column of fat is less than about one division, as will sometimes happen with skimmilk, buttermilk or whey it may assume a globular form instead of a uniform layer across the tube; when this occurs the fat can usually be estimated with sufficient accuracy by simple inspection, but if an accurate reading is desired it may be obtained by taking four samples of the milk in four test bottles, and after treating them in...
