an order of fishes, small in number, but of great importance as exhibiting a distinct transition between the fishes and amphibia. So many are the points of resemblance between the two, that until recently the Lepidosiren was always made made to constitute the lowest class of amphibia. The highest authorities, however, now concur in placing it among the fishes. The order Dipnoi is thus defined: the body is fish-like in shape; there is a skull with distinct cranial bones and a lower jaw, but the notochord is persistent, and there are no vertebral centra, nor an occipital condyle. The exo-skeleton consists of horny, overlapping scales, having the cycloid character. The pectoral and ventral limbs are both present, but have (in Lepidosiren) the form of awl-shaped, filiform, many-jointed organs of which the former only have a membranous fringe inferiorly. Until recently the only two members of the order were the Lepidosiren paradoxa of South America, and the L. annectens of Africa.

Important: Safety Warning This page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes. This information has been left in for historical purposes but should not be acted upon. A process by which a bright surface is imparted to the alloy or metal after it has undergone the process of pickling, scouring, and washing. Dipping consists of immersing the article in pure nitrous acid for a moment, but no iron or wood implements are to be used. Brass tongs are best for this purpose, and the vessels should be earthenware. If the work appears coarse and spotted after dipping, the dip must be repaired by adding sulphuric acid; should it be too smooth after it has been dipped, add muriatic acid and nitric till it shows the right appearance. Dips should be kept stirred, and not allowed to settle whilst using. See STAINING METALS; PICKLING; ORMOLU DIPPING ACID; QUICK DIPPING-ACID; LACQUERING.
