These are of two kinds, one for grinding and the other for polishing. The grinding mills are copper discs, from an inch to an inch and a half in diameter, into the surface of which diamond powder of various grades has been hammered or rolled. The polishing mills are made of box-wood, vegetable ivory, etc., and the powder is applied to their surfaces in the shape of a paste mixed with olive oil. These mills are useful for cutting or polishing ruby-pallets, and other hard stones, for flattening stones to be used as jewels and for manipulating hard steel.

a daily record of events or observations made by an individual. Diaries have often furnished the historian with invaluable material, supplying the absence of public records, and furnishing minute and intimate details of manners and of motives that do far more to help us to understand the past than more formal records. Such documents as Robert Baillie's "Journals," the "Diaries" of Pepys and Evelyn, and the "Journals" of Greville are among the most valuable sources of real history. DIAS. See DIAZ.

Bartholomew (1445-1500), a Portuguese navigator. He was a member of the royal household. In 1486 he obtained command of an expedition sent out to explore the coast of western Africa. Whether by luck or by storm, he lost his way; the two ships rounded the southern extremity of Africa without knowing it, and reached the coast at a point east of the Cape of Good Hope . He explored the eastern coast for about 500 miles and returned via the Cape with the great news of an open sea route to India. In 1498 Dias started with Vasco da Gama's fleet, but fell behind to trade on the African coast. He accompanied Da Gama again in 1500. His ship was lost in a storm off the coast of Brazil.

a substance existing in barley, oats, and potatoes, but only after germination. When in solution it possesses the property of causing fecula or starch to break up at the temperature of 150° F., transforming it first into dex- -trine and then into sugar. It is obtained by digesting in a mixture of three parts of water and one of alcohol, at a temperature of 113° F., a certain quantity of germinated barley ground and dried in the open air, and then putting the whole under pressure and filtering it. Diastase is solid, white, and soluble in water quently diarrhea results from unwhole- and diluted alcohol, but insoluble in strong alcohol.

an order of microscopic plants usually referred to the class Algæ. There are more than 4,000 distinct species scattered over all parts of the world. The walls of the cells are rendered hard by silica and they are reproduced by fission, the splitting taking place parallel to the longer axis. When the protoplasm escapes the cell walls retain their shapes and delicate markings. Enormous quantities of them are found as fossils in the beds of the Tertiary formation. Often the protoplasm of two diatoms will escape and unite to form a zygospore, which after a time will divide into two, each forming a new cell larger than before. Some diatoms are free and move rapidly through the water; others secrete a mucilaginous substance whereby they attach themselves to various objects. In some cases the diatoms, after splitting, remain attached to one another, forming bands or ribbons. They are classified, according to the structure of the cell walls, three main families being recognized, according as they have on the principal face of the wall a distinct ridge (Raphidieæ), an indistinct or false ridge (Pseudoraphidieæ), or no ridge at all (Araphidieæ or Cryptoraphidiex).
