Milky grains

Grains which had a milky appearance because of the precipitation of the colloid during the water-dry treatment. This result follows if the grains contain more than 7 or 7.5% of ether-alcohol when they are submitted to water-drying. 

When 1 gram (15.4 grains) is shaken in a test tube wiUi 15 c.o. (4 fi 3 ) of ether, and 2 e.c. (82 tTl.) of NH HO the liquids should separate into two clear layers, without any milky none between them (cin-cbonine). 

Solution of Citrate of Bismuth. Put 2 ounces pure sub-nitrate of bismuth into a porcel dish, add 1450 grains nitric acid of specific gravity 1.44 heat over a spirit lamp until the bismuth is dissolved then add one fluid ounce water, and let stand until cold then gradually add water, constantly stirring with a glass rod, until a further addition produces milkiness, or until the whole measures 1 pints. Filter and set aside. 

Approximately 99 % of the mass of the interstellar medium is in the form of gas (where denser regions are termed interstellar clouds) with the remainder primarily in the form of dust. The total mass of the gas and dust in the interstellar medium is about 15 % of the total mass of visible matter in the Milky Way. The exact nature and origin of interstellar dust grains is unknown, but they are presumably ejected from stars. One likely source is from red giant stars late in their lives. Interstellar dust grains are typically a fraction of a micron across, irregularly shaped, and composed of carbon an or silicates. 

There is a limited market for com-on-the-cob or sweet com as a vegetable. This latter is a special type of maize in which some of the sugar produced is not converted into starch and is harvested when the grain is in the milky stage.
