MiJCRE, Heinrich Karl Anton, a German painter, born in Breslau, April 9, 1806. He completed his studies in Berlin under Schadow, whom he accompanied to Diisseldorf, where he became in 1844 teacher of anatomy at the academy. In 1849 he was appointed professor and subse- quently member of the academical senate, which offices he resigned in 1867. He visited Italy and England, and was employed in painting in the former country, and on designs for the " Art Journal " in the latter. Among his principal works are frescoes in the palace of Heltorf, near Dusseldorf, illustrating the life of Fred- erick Barbarossa, with Lessing and other ar- tists ; and a large fresco in St. Andrew's church at Dusseldorf. His fine frescoes for the Elber- f eld town hall have been destroyed. Among his most celebrated oil paintings is " St. Catharine carried by Angels to Mount Sinai." His other works include " The Storming of Jerusalem by Godfrey of Bouillon," "The Crowning of the Virgin," "The Resurrection," and many etchings and designs for illustrated works. MUOOUS MEMBRANE. See MEMBKANE. MUCUS, a transparent, colorless, and glairy or viscid fluid, exuded upon the free surface of the mucous membranes of the living body. It is the secretion of the numerous glandulse or follicles with which these membranes are pro- vided, and varies in the details of its composi- tion and the degree of its viscidity with the particular region in which it is produced and the special function which it is destined to per- form. It does not readily mix with water, but when agitated with that liquid is broken up into floating shreds or flakes, which are apt to become frothy from the entanglement of bub- bles of air. It consists of water combined with a small quantity of the mineral salts, and a peculiar variety of animal or organic matter termed mucosine; to this last ingredient the glairy or viscid consistency of mucus is mainly due. The office of mucus is to lubricate the mucous canals and thus facilitate the passage of their contents, as in the mouth, oesophagus, and genito-urinary passages; to protect their surfaces from injury by desiccation, as in the nares, trachea, and bronchial tubes ; or to take part in the chemical changes going on in their cavities, as in the small intestine. In the cer- vix uteri, during gestation, the mucus has so great a degree of viscidity as to be semi-solid like gum or strong paste ; its office is to block up the cavity of the cervix uteri and prevent the escape or injury of the foetus. MUD EEL. See SIEEN. MUD FISH (amia, Linn.), a genus of American ganoids, found in the fresh waters of the United States. After it had been referred by ichthy- ologists to cyprinoid, salmonoid, and clupeoid fishes, Vogt discovered it to be a ganoid, hav- ing found in the muscular arterial trunk two oblique rows of five or six valves each and a spiral intestinal valve. Muller considers it the living representative of a ganoid family, like the fossil megalurus, leptolepis, and their con- geners. The body is long and flexible, with a bony vertebral column ; there are no spiny plates on the anterior border of the fins as in the gar fish, nor a series of separate dorsal fins as in polypterus; the mouth is trout-like, ex- cept in the absence of lingual teeth ; there are two nasal cirri ; the head is flat, and the bones under the very thin skin are sculptured plates; the large sublingual bone is naked and fur- rowed, the gill openings large, and the bran- chiostegal rays broad and flat, 11 or 12; tongue thick and fleshy ; behind the conical teeth of the jaws are flat pavement-like ones ; the scales are horny rather than osseous, flexible and rounded, yet presenting bone corpuscles of the same form and character as lepidosteus and other ganoids; the ventral fins are median, the single dorsal long, and the anal short ; the Western Mud Fish (Amia occidentalis). caudal comes further forward above than below, rounded, giving an indication of the heterocercal tail. The larger air bladder is cellular and lung-like, communicating with the
