LACTOSE (milk sugar, galactine, lac- ilk sugar, galactine, lactine), is one of the sucrose group of sugars-disaccharides-in chemistry, Cizarides in chemistry, chem C H22O11. Although isomeric, that is, of h isomeric, that is, of LACUNA the same chemical composition, with sucrose (cane sugar), lactose is less sweet and less soluble. It makes up 4.9% of ordinary milk. It crystallizes into orthorhombic crystals, dextrorotatory in polarized light. Lactose can be separated into galactose and glucose and oxygen.
LACUNA (lā-kūnä), plural LA- CUNE (-nē), in human anatomy, open spaces, prolonged into canaliculi or delicate tubes finer than the smallest capillary vessels, occurring in bone. The lacunæ have an average length of 1-1800 of an inch, and are about half as wide and a third as thick. In botany (1) Singular, Link's name for an air-cell in a plant. (2) Plural, Small hollows or pits upon the under surface of the thallus in a lichen. In zoölogy, a genus of Littorinidæ. Sixteen recent species are known and one fossil, the former from Norway, Great Britain, Spain, etc., the latter from the Scotch glacial beds.
LADANUM (lad'-), in chemistry, C20H3O3; labdanum; an odorous, resinous substance which exudes in drops from the leaves and twigs of the Cistus creticus , a shrub growing in the island of Candia and in Syria. It is a darkcolored, tenacious resin, somewhat moist, exhaling an odor like that of ambergris.
It was formerly much used for making stimulating plasters. Ladanum in sticks is prepared in Portugal, Spain, and the S. of France by boiling the leaves and branches of Cystus ladaniferus.
LADOGA quarters are at Erie, Pa., and members are drawn from all over the United States. In 1916 the association had 157,525 members, and 1,253 branches.
Its disbursements in death benefits had been $13,640,007.48, with relief benefits of $23,560.
