Splenotomy :: Splenotomy (n.) Dissection or anatomy of the spleen.

Trivalent :: Trivalent (a.) Having a valence of three; capable of being combined with, substituted for, or compared with, three atoms of hydrogen; -- said of triad atoms or radicals; thus, nitrogen is trivalent in ammonia..

Kamichi :: Kamichi (n.) A curious South American bird (Anhima, / Palamedea, cornuta), often domesticated by the natives and kept with poultry, which it defends against birds of prey. It has a long, slender, hornlike ornament on its head, and two sharp spurs on each wing. Although its beak, feet, and legs resemble those of gallinaceous birds, it is related in anatomical characters to the ducks and geese (Anseres). Called also horned screamer. The name is sometimes applied also to the chaja. See Chaja, and S

Alkalamide :: Alkalamide (n.) One of a series of compounds that may be regarded as ammonia in which a part of the hydrogen has been replaced by basic, and another part by acid, atoms or radicals..

Quadrivalent :: Quadrivalent (a.) Having a valence of four; capable of combining with, being replaced by, or compared with, four monad atoms; tetravalent; -- said of certain atoms and radicals; thus, carbon and silicon are quadrivalent elements..

Amine :: Amine (n.) One of a class of strongly basic substances derived from ammonia by replacement of one or more hydrogen atoms by a basic atom or radical.

Anatomically :: Anatomically (adv.) In an anatomical manner; by means of dissection.

Hexeikosane :: Hexeikosane (n.) A hydrocarbon, C26H54, resembling paraffine; -- so called because each molecule has twenty-six atoms of carbon..

Scapulo- :: Scapulo- () A combining form used in anatomy to indicate connection with, or relation to, the scapula or the shoulder; as, the scapulo-clavicular articulation, the articulation between the scapula and clavicle..

Residue :: Residue (n.) That which remains of a molecule after the removal of a portion of its constituents; hence, an atom or group regarded as a portion of a molecule; -- used as nearly equivalent to radical, but in a more general sense..

Iodine :: Iodine (n.) A nonmetallic element, of the halogen group, occurring always in combination, as in the iodides. When isolated it is in the form of dark gray metallic scales, resembling plumbago, soft but brittle, and emitting a chlorinelike odor. Symbol I. Atomic weight 126.5. If heated, iodine volatilizes in beautiful violet vapors..

Posterior :: Posterior (a.) At or toward the caudal extremity; caudal; -- in human anatomy often used for dorsal.

Polybromide :: Polybromide (n.) A bromide containing more than one atom of bromine in the molecule.

Lead :: Lead (n.) One of the elements, a heavy, pliable, inelastic metal, having a bright, bluish color, but easily tarnished. It is both malleable and ductile, though with little tenacity, and is used for tubes, sheets, bullets, etc. Its specific gravity is 11.37. It is easily fusible, forms alloys with other metals, and is an ingredient of solder and type metal. Atomic weight, 206.4. Symbol Pb (L. Plumbum). It is chiefly obtained from the mineral galena, lead sulphide..

Boron :: Boron (n.) A nonmetallic element occurring abundantly in borax. It is reduced with difficulty to the free state, when it can be obtained in several different forms; viz., as a substance of a deep olive color, in a semimetallic form, and in colorless quadratic crystals similar to the diamond in hardness and other properties. It occurs in nature also in boracite, datolite, tourmaline, and some other minerals. Atomic weight 10.9. Symbol B..

Butyl :: Butyl (n.) A compound radical, regarded as butane, less one atom of hydrogen..

Tetrad :: Tetrad (n.) A tetravalent or quadrivalent atom or radical; as, carbon is a tetrad..

Monosulphide :: Monosulphide (n.) A sulphide containing one atom of sulphur, and analogous to a monoxide; -- contrasted with a polysulphide; as, galena is a monosulphide..

Neodymium :: Neodymium (n.) An elementary substance which forms one of the constituents of didymium. Symbol Nd. Atomic weight 140.8.

Subaud :: Subatom (n.) A hypothetical component of a chemical atom, on the theory that the elements themselves are complex substances; -- called also atomicule..
