(fe-noz' -ig-us). In craniometry," having the zygomatic arches visible directly from above; having the bizygomatic diameter greater than the maximum transverse frontal diameter, and the angle of Quat ref ages positive." Phenyl (fe/-nil) 1 1 -,. A univalent organic radical. P. -acetic Acid. Acid. P. -amid, a compound formed by the substitution of one or more amido-groups for the hydrogen of benzene; anilin is a phenyl a mid. P.-amin. Synonym of Anilin. P.-auramin. See Pigments, Conspectus of.

P.-end i am in Preferably diamidobenzene; a chemic substance of which there are three isomeric forms, distinguished by the prefixes ortho-, inefa-, para-. P.ethylene. See Styrol. P.-glucosazone, C.J I. It crystallizes in yellow needles, is almost insoluble in water, very slightly soluble in hot alcohol, molts at about 2050 C., and is levo-rotatory when di olved in glacial acid. P. -glycerol. See Stycerin . P.-glycuronic Acid, a levo-rotatory, crystalline body occurring in the urine after the administration of carbolic Dilute acid decomposes it into carbolic and acids. P.-hydrazin, a substance obtained from benzene diazo chlorid by reduction with sodium sulphite or stannous chlorid. It is a colorle , peculiar smelling oil, solidifying, when cooled, to plat i crystals, melting at 230 C.; sp. gr. I.oqi at.: 1 It boils at 241-2420 C. It di olves with great difficulty in cold water, but readily in alcohol and ether. P.-h. Test (for sugar). Into a test tube put ' in. dry phenyl-hydrazin hydro chlorate; add pulverized sodium acetate an equal volume; and fill one-half of the tube with urine. Agitate until the sodium acetate is di olved, gently heating up to the boiling-point and boil for 30 seconds. Examine the sediment with the microscope for yellow, branching, needle-shaped crystals of phenyl-glucosazone. See Tests, Table of. P. Hydrid, benzene. P.-lac to saz one, a compound of lactose with phenyl-hydrazin; it is soluble in 80-90 parts of boiling water, and melts at about 2000 C. It crystallizes readily in the form of yellow needles usually aggregated into clusters.
