FOSSIL ANIMALS.
Of these the most interesting specimens are the remains of the Marine Lizards known as ichthyosauri from the English lias formation. To the right on entering, against the eastern wall of the room, the visitor should first notice the fossil remains of various carnivorous animals, including the skulls and other osseous wrecks of hyenas, bears, &c., and also, carefully screened in an additional glass case, hereabouts, the lower jaw of a marsupial animal on a slab of oolitic limestone—an early deposit, in which the highest class fossils generally found are the tortoises.
In this room, however, the visitor will notice the progress of early creation—first, the zoophytes; then the fish lizards; then the fossil ruminants; then the fossil carnivora. Examples of these fossil remains are all included in the room which the visitor has now reached. First, he should examine the fossil remains of the ichthyosauri, or fish lizards, ranged in the first three wall cases, particularly that eighteen feet in length, deposited in the third case, one on the upper shelf of the fourth case, and another on the upper shelf of the fifth case. The case marked F contains fossils of a higher order than the reptiles, as the bones and antlers of deer, found in later strata of the earth's crust; and on the top of the case are the horn and skull of a species of Texan bos. Having noticed these curious remains, principally of extinct species of animal life, the visitor should at once turn to the table cases which contain the last of the illustrations of the mineral kingdom.
MINERALS.
The southern tables include the numbers 24 to 30. The first table contains a very attractive collection of minerals, including the varieties of jasper; all kinds of opals—the sun opal, the semi-opal, wood opal, and wood partially opalised. The second table (25) is covered with varieties of Silicates of Lime, magnesia, and alumina; also soapstone, keffekil, or the meerschaum, highly esteemed by smokers, serpentine, chrysolite, &c. The third case (26) is devoted to Silicates of Zinc, magnesia, serium, copper, iron, bismuth, and other minerals; the fourth and fifth cases (27, 28) to zoolitic substances; the sixth case (29) to various minerals including samples of jade or nephrite, of which the tortoise, in the first room of this gallery, is manufactured; and the seventh case (30) to felspathic substances, including amazon stone from the Urals, and Labrador felspar. The northern cases are numbered from 31 to 37. In the first case (31) are varieties of felspar; in the second case (32) are micaceous and other mineral substances; in the third case (33) are basaltic hornblende, tremolite, &c.; in the fourth case (34) are varieties of asbestus, which defies the action of fire; jeffersonite; jenite from the Elba, &c.; in the fifth case (35) are various pyroxenic minerals; in the sixth case (36) are various kinds of garnets, including the lime and chrome varieties; and in the 37th case are the silicates, including beryls, and the emerald.
Having brought his examination of the mineral kingdom to a conclusion, the visitor should notice the fossil zoophytes and shells from various deposits, arranged upon the other tables of the room. He will now leave the mineral kingdom, and advancing once more westward, will reach the fifth room of the gallery, which is entirely given up to various fossil remains.
FOSSIL FISHES
The first object that will arrest the visitor's attention on entering this fine apartment is the gigantic skeleton of the extinct elk of Ireland, which towers above every other object, from its pedestal, placed in the centre of the room. It is seven feet in height, and eight feet in length.
The southern wall cases and the southern table cases of this room are covered with the fossil remains of various fishes. These are important to the student as exhibiting high forms of animal life that existed at the time of the formation of the most ancient strata in which organic remains have been discovered. The visitor will notice the perfect forms imprinted upon the various strata here exhibited.
In case 7 he will be struck with the fossil remains of some of the sauroids or lizard-like fishes, only two species of which survive to the present day, but which, in remote ages, abounded in the seas, and were particularly voracious. On the middle shelf of the wall case marked B the visitor should notice the fossil remains of the enormous and powerful carnivorous fish called the rhizodus; also the macropoma, like a carp in shape, in wall cases 13, 14; the fossil bremus in case 19; the extinct species of fossil carps, in cases 24, 25; the fossil pikes in cases 24-27; and the fossil herrings in the middle of cases 25-27. Having noticed these fossils the visitor should examine the wall case in the north-eastern corner of the room in which are deposited many bones of mammalia from the Sewalik Hills, including the teeth and jaws of an extinct species of camel; and the skull of the remarkable livatherium; and on the top of the case are various bones of the same extinct monster. The tops of the southern cases display various fossil remains, including the head-bones of the asterolepis; the skull and antlers of the Irish elk; and various skulls of different kinds of oxen. The western wall case is filled with a curious collection of various fossil parts of an extinct species of rhinoceros found in this country, also skulls of the rhinoceros dug up in Siberia. There is something impressive in the effect—the atmosphere of this and the sixth rooms. As crowds of holiday people, inhabitants of an island in which no dangerous living animals now abide, wander amid the fossil remnants of ages when the most terrible monsters must have lived in British waters and crawled upon British ground, curious contrasts rise in the brains of contemplative men. The mind wanders back to the age of reptiles—to times when no human footprint had sunk into the earth—and the great agents of nature were silently depositing in the congregating and shifting earths dead images of the prevailing life. Ages roll on as the reptiles give place to higher animal organisation developed in carnivora, the quickening blood warms, and then as the sovereign of all the grades of life, erect and gifted with reason, comes man. Something of this vast and half-told progress is shown in the range of fossil cases with which the visitor is engaged. He has passed the era of reptiles and fishes, and on entering the sixth and last room of the gallery, he will notice the higher series of fossils. The distribution of the
