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.
