Phlebology :: Phlebology (n.) A branch of anatomy which treats of the veins.

Vanadium :: Vanadium (n.) A rare element of the nitrogen-phosphorus group, found combined, in vanadates, in certain minerals, and reduced as an infusible, grayish-white metallic powder. It is intermediate between the metals and the non-metals, having both basic and acid properties. Symbol V (or Vd, rarely). Atomic weight 51.2..

Particle :: Particle (n.) A minute part or portion of matter; a morsel; a little bit; an atom; a jot; as, a particle of sand, of wood, of dust..

Gorilla :: Gorilla (n.) A large, arboreal, anthropoid ape of West Africa. It is larger than a man, and is remarkable for its massive skeleton and powerful muscles, which give it enormous strength. In some respects its anatomy, more than that of any other ape, except the chimpanzee, resembles that of man..

Pentacid :: Pentacid (a.) Capable of neutralizing, or combining with, five molecules of a monobasic acid; having five hydrogen atoms capable of substitution by acid residues; -- said of certain complex bases..

Unisilicate :: Unisilicate (n.) A salt of orthosilicic acid, H4SiO4; -- so called because the ratio of the oxygen atoms united to the basic metals and silicon respectively is 1:1; for example, Mg2SiO4 or 2MgO.SiO2..

Tympano- :: Tympano- () A combining form used in anatomy to indicate connection with, or relation to, the tympanum; as in tympanohyal, tympano-Eustachian..

Germanium :: Germanium (n.) A rare element, recently discovered (1885), in a silver ore (argyrodite) at Freiberg. It is a brittle, silver-white metal, chemically intermediate between the metals and nonmetals, resembles tin, and is in general identical with the predicted ekasilicon. Symbol Ge. Atomic weight 72.3..

Iridium :: Iridium (n.) A rare metallic element, of the same group as platinum, which it much resembles, being silver-white, but harder, and brittle, and indifferent to most corrosive agents. With the exception of osmium, it is the heaviest substance known, its specific gravity being 22.4. Symbol Ir. Atomic weight 192.5..

Uvulatome :: Uvulatome (n.) An instrument for removing the uvula.

Triatomic :: Triatomic (a.) Having a valence of three; trivalent; sometimes, in a specific sense, having three hydroxyl groups, whether acid or basic; thus, glycerin, glyceric acid, and tartronic acid are each triatomic..
