[Gr. megistos very great, and our a =a tail.] Ornith.: Long-tailed Tit. It was raised to generic distinction as Mecistura vagans , by Dr. Leach in 1816, without, however, specifying his reasons. He has been followed by Brehm and Bonaparte. (Yarrell.) [PARUS, TIT.] Mě-chō-a-căn, s. [See def.] The name of a maritime state in Mexico, whence the root was originally brought. Me cho a can-root, s. Bot. & Pharm .: The root of Batatas jalap a , once erroneously supposed to be the true jalap, which it to a certain extent resembles in its purgative properties. Měc-kel, s . [See def.] John Frederick Meckel, a celebrated German anatomist (1724-74). He was the author of many scientific works, and, in 1749, published an account of the ganglion which bears his name. Meckel's-cartilage, s . Anat.: The cartilage of the first or mandibular arch. It occupies the deeper part of the arch from a very early period, and remains visible in the human fœtus up to the sixth or seventh month. Its proximal portion is converted into the malleus of mammals and the quadrate bone of reptiles and birds. ( Quain .) Meckel's-ganglion, s . Anat .: The larger of the cranial ganglia. It is triangular in shape, reddish in color, and is situated in the spheno-maxillary fo a, near the sphenopalatine foramen, whence it is sometimes called the spheno-palatine ganglion. The sub-maxillary ganglion was also discovered by Meckel. mě-com-ě-těr, subst. [Gr. mēkos =length, and metron a measure.] Surg .: A graduated instrument used at the Hospico de Maternité in Paris, to measure new-born IMG:content-1044.png:[blocks in formation] Chemistry: C7H3(NH2)O6=C+(NH2) COHO. An COHO amide of meconic acid formed by the action of ammonia on ethyl meconic acid. It has not been obtained in the crystalline form, and its formula is somewhat doubtful. měc-o-nāte, subst. [Eng. mecon (ic); suff. -ate.] Chem.: A salt of meconic acid. mě-con-ic, adj. [Eng., ., mecon(ium); suff. -ic.] Contained in or derived from meconium (q. v.). meconic-acid, s. Chemistry: C7H4O7. One of the constituents of opium discovered by Sertürner in 1805. It is prepared from the alcoholic extract of opium by precipitating with baric chloride and decomposing the baric meconate with sulphuric acid. It crystallizes in colorle , mica-like plates or prisms, containing three molecules of water, with difficulty soluble in cold water and other but readily in hot water bonic anhydride, and is converted into comenic acid, C6H4O5. Its aqueous solution is colored deepred by ferric chloride. Meconic acid is dibasic, When heated to 200°, it gives off car and forms two cla es of salts. When calcic meconate is di olved in warm nitric acid, and the solution cooled, brilliant plates of the monobasic salt (C7H307)2Ca, 2H2O are produced. Di-ammonic meconate, CHO (CO(NH4)O)2, crystallizes in slender needles. IMG:content-1045.png:[blocks in formation] marine; gō, pot, meconidine
