Olein :: Olein (n.) A fat, liquid at ordinary temperatures, but solidifying at temperatures below 0¡ C., found abundantly in both the animal and vegetable kingdoms (see Palmitin). It dissolves solid fats, especially at 30-40¡ C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain..

Bathybius :: Bathybius (n.) A name given by Prof. Huxley to a gelatinous substance found in mud dredged from the Atlantic and preserved in alcohol. He supposed that it was free living protoplasm, covering a large part of the ocean bed. It is now known that the substance is of chemical, not of organic, origin..

Acidimetry :: Acidimetry (n.) The measurement of the strength of acids, especially by a chemical process based on the law of chemical combinations, or the fact that, to produce a complete reaction, a certain definite weight of reagent is required..

Molecule :: Molecule (n.) A group of atoms so united and combined by chemical affinity that they form a complete, integrated whole, being the smallest portion of any particular compound that can exist in a free state; as, a molecule of water consists of two atoms of hydrogen and one of oxygen. Cf. Atom..

Hermetically :: Hermetically (adv.) In an hermetical manner; chemically.

Chemist :: Chemist (n.) A person versed in chemistry or given to chemical investigation; an analyst; a maker or seller of chemicals or drugs.

Slacken :: Slacken (a.) To lose cohesion or solidity by a chemical combination with water; to slake; as, lime slacks..

Chemosmosis :: Chemosmosis (n.) Chemical action taking place through an intervening membrane.

Stoicism :: Stoichiometry (n.) The art or process of calculating the atomic proportions, combining weights, and other numerical relations of chemical elements and their compounds..

Bolthead :: Bolthead (n.) A long, straight-necked, glass vessel for chemical distillations; -- called also a matrass or receiver..

Macro-chemistry :: Macro-chemistry (n.) The science which treats of the chemical properties, actions or relations of substances in quantity; -- distinguished from micro-chemistry..

Anion :: Anion (n.) An electro-negative element, or the element which, in electro-chemical decompositions, is evolved at the anode; -- opposed to cation..

Generation :: Generation (n.) Origination by some process, mathematical, chemical, or vital; production; formation; as, the generation of sounds, of gases, of curves, etc..

Mechanico-chemical :: Mechanico-chemical (a.) Pertaining to, connected with, or dependent upon, both mechanics and chemistry; -- said especially of those sciences which treat of such phenomena as seem to depend on the laws both of mechanics and chemistry, as electricity and magnetism..

Blancher :: Blancher (n.) One who, or that which, blanches or whitens; esp., one who anneals and cleanses money; also, a chemical preparation for this purpose..

Neurine :: Neurine (n.) A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide..

Neutralize :: Neutralize (v. t.) To render inert or imperceptible the peculiar affinities of, as a chemical substance; to destroy the effect of; as, to neutralize an acid with a base..

Force :: Force (n.) Any action between two bodies which changes, or tends to change, their relative condition as to rest or motion; or, more generally, which changes, or tends to change, any physical relation between them, whether mechanical, thermal, chemical, electrical, magnetic, or of any other kind; as, the force of gravity; cohesive force; centrifugal force..

Allomerism :: Allomerism (n.) Variability in chemical constitution without variation in crystalline form.

Actinology :: Actinology (n.) The science which treats of rays of light, especially of the actinic or chemical rays..
