 dressed and deprived of the longer harsh outer hairs, constitute the “sealskin” of commerce. The species include O. stelleri, the northern sea-lion, the largest of the genus, from the North Pacific, about 10 ft. in length; O. jubata, the southern sea-lion, from the Falkland Islands and Patagonia; O. californiana, from California; O. ursina, the sea-bear or fur-seal of the North Pacific, the skins of which are imported in immense numbers from the Pribiloff Islands; O. antarctica or pusilla, from the Cape of Good Hope; and O. forsteri, from Australia and various islands in the southern hemisphere. (See .)

Little is known as to the past history of the sea-lions and sea-bears, but a skull has been obtained from the Miocene strata of Oregon, which Mr F. W. True states to be considerably larger than any existing sea-lion skull; its basal length when entire being probably about 20 in. The name Pontoleon magnus has been proposed for this fossil sea-lion, as the character of the skull and teeth do not agree precisely with those of any living member of the group. If, however, all the modern eared seals are included in the genus Otaria, there is apparently no reason to exclude the fossil species.

Modern Carnivora are undoubtedly the descendants of the (q.v.), an extinct early Tertiary suborder. It has been observed that as the Miocene is approached, some of these Carnivora Creodonta, or Primitiva, begin to assume more and more of the characteristics of the Carnivora Vera, till at last it is difficult to determine where the one group ends and the other commences. The creodont genera Stypolophus and Proviverra show some of these modern characters; but it is not till we reach the European Oligocene genus Amphictis, with the dental formula i. , c. , p. , m. , that we meet a type in which the fourth upper premolar and the first lower molar assume the truly sectorial character of the Carnivora Vera, while the teeth behind them are proportionally reduced in size. From the Amphictidae are probably descended the Viverridae, the connecting genus being the African Nandinia, which, as already mentioned, retains the imperfectly ossified bulla of the ancestral forms. In another direction, Amphictis, through the Old World Lower Pliocene genus Ictitherium, has given rise to the Hyaenidae. The Felidae have apparently an ancestral type in the creodont Palaeonictis, which has been regarded as the direct ancestor of the sabre-toothed cats, or Machaerodontinae (see ); but it is possible that Palaeonictis may be off the direct line, and that the Felidae are sprung from Amphictis. Be this as it may, from another group of creodonts, represented by Vulpavus (Miacis), Viverravus (Didymictis), and Uintacyon, is probably derived the Oligocene Cynodictis, with a dental formula like that of Canis or Cyon, a perforation to the humerus, and an apparently undivided auditory bulla; and from Cynodictis the transition is easy to the Canidae. It should be mentioned, however, that there is a group of North American Oligocene dog-like animals, such as Daphaenus, Protemnocyon, and Temnocyon, which agree with Cyon in the shortness of the jaws, and with that genus and Speothos in the cutting-heel of the lower sectorial. Possibly these genera may be nearly related to Cyon. Other dog-like North American types are Oligohinis, Enhydrocyon and Hyaenocyon.

By means of the Amphicyonidae, as represented by the Middle Tertiary genera Proamphicyon, Pseudamphicyon, and Amphicyon, in which there were three upper molars, we have a transition from the Cynodictis-type to the bear-group; one of the later intermediate forms being the Lower Pliocene Old World Hyaenarctus, in which the two upper molars are squared and foreshadow those of Ursus itself. In some unknown manner Hyaenarctus appears to be related to Aeluropus. An allied type is found in Arctotherium of the South American Pleistocene.

By the loss of the third lower molar and certain modifications of the other teeth and skull, the Miocene genus Plesictis may be derived from Cynodictis, its dental formula being i. , c. , p. , m. . Now Plesictis is nothing more than a generalized representative of the Mustelidae. We have thus traced three out of the four modern arctoid families to the Cynodictis-type. The Procyonidae, or fourth family (apart from the Asiatic Aelurus and Aeluropus) are connected with the last-named genus through the North American Oligocene Phlaeocyon, which is stated to be in almost every respect intermediate between Procyon and Cynodictis while the living Bassariscus is stated to show closer signs of affinity with Cynodictis than with Phlaeocyon.

To deal with fossil representatives of living genera, or extinct genera nearly related to groups still existing, would here be impracticable. It may be stated, however, that aberrant groups like the otters are linked up with more normal types by means of extinct forms (in this particular instance by the Miocene Potamotherium), so that the gaps in the phylogeny of the Carnivora are comparatively few.

 CARNOT, LAZARE, HIPPOLYTE (1801–1888), French statesman, the second son of (q.v.), was born at Saint-Omer on the 6th of October 1801. Hippolyte Carnot lived at first in exile with his father, returning to France only in 1823. Unable then to enter active political life, he turned to literature and philosophy, publishing in 1828 a collection of Chants helléniques translated from the German of W. Müller, and in 1830 an Exposé de la doctrine Saint-Simonienne, and collaborating in the Saint-Simonian journal Le Producteur. He also paid several visits to England and travelled in other countries of Europe. In March 1839, after the dissolution of the chamber by Louis Philippe, he was elected deputy for Paris (re-elected in 1842 and in 1846), and sat in the group of the Radical Left, being one of the leaders of the party hostile to Louis Philippe. On the 24th of February 1848 he pronounced in favour of the republic. Lamartine chose him as minister of education in the provisional government, Carnot set to work to organize the primary school systems, proposing a law for obligatory and free primary instruction, and another for the secondary education of girls. But he declared himself against purely secular schools, holding that “the minister and the schoolmaster are the two columns on which rests the edifice of the republic.” By this attitude he alienated both the Right and the Republicans of the Extreme Left, and was forced to resign on the 5th of July 1848. He was one of those who protested against the coup d’état of the 2nd of December 1851, but was not proscribed by Louis Napoleon. He refused to sit in the Corps Législatif until 1864, in order not to have to take the oath to the emperor. From 1864 to 1869 he was in the republican opposition, taking a very active part. He was defeated at the election of 1869. On the 8th of February 1871 he was named deputy for the Seine et Oise, and participated in the drawing up of the Constitutional Laws of 1875. On the 16th of December 1875, he was named by the National Assembly senator for life. He died on the 16th of March 1888, three months after the election of his elder son, (q.v.), to the presidency of the republic. He had published Le Ministère de l’instruction publique et des cultes du 24e février au 5e juillet 1848, (1849), Mémoires sur Lazare Carnot (2 vols., 1861–1864), Mémoires de Barère (with David Angers, 4 vols., 1842–1843). His second son, Marie Adolphe Carnot (b. 1839), became a distinguished mining-engineer and director of the École des Mines (1899), his studies in analytical chemistry placing him in the front rank of French scientists. He was made a member of the Academy of Sciences in 1895.

 CARNOT, LAZARE NICOLAS MARGUERITE (1753–1823), French general, was born at Nolay in Burgundy in 1753. He received his training as an engineer at Mézières, becoming an officer of the Corps de Génie in 1773 and a captain ten years later. He had then just published his first work, an Essai sur les machines en général. In 1784 he wrote an essay on balloons, and his. Éloge of Vauban, read by him publicly, won him the commendation of Prince Henry of Prussia. But as the result of a controversy with Montalembert, Carnot abandoned the official, or Vauban, theories of the art of fortification, and went over to the “perpendicular” school of Montalembert. He was consequently imprisoned, on the pretext of having fought a duel, and only released when selected to accompany Prince Henry of Prussia in a visit to Vauban’s fortifications. In 1791 he married. The Revolution drew him into political life, and he was elected a deputy for the Pas de Calais. In the Assembly he
