ng itself up in a ball, becomes dormant. A
warmer day than usual restores it to temporary activity, and then it
supplies itself with food from its autumn hoard, again becoming torpid
till roused by the advent of spring. The young are generally four in
number, and are produced twice a year. They are born blind, but in a
marvellously short period are able to cater for themselves; and their
hibernation begins later in the season than with the adults. The fur of
the dormouse is tawny above and paler beneath, with a white patch on the
throat. A second subfamily is represented by the Indian _Platacanthomys_
and the Chinese _Typhlomys_, in which there are only three pairs of
cheek-teeth; thus connecting the more typical members of the family with
the _Muridae_. (R. L.*)

DORNBIRN, a township in the Austrian province of the Vorarlberg, on the
right bank of the Dornbirner Ach, at the point where it flows out of the
hilly region of the Bregenzerwald into the broad valley of the Rhine, on
its way to the Lake of Constance. It is by rail 7-1/2 m. S. of Bregenz,
and 15 m. N. of Feldkirch. It is the most populous town in the
Vorarlberg, its population in 1900 being 13,052. The name Dornbirn is a
collective appellation for four villages--Dornbirn, Hatlerdorf, Oberdorf
and Haselstauden--which straggle over a distance of about 3 m. It is the
chief industrial centre in the Vorarlberg, the regulated Dornbirner Ach
furnishing motive power for several factories for cotton spinning and
weaving, worked muslin, dyeing, iron-founding and so on.

DORNBURG, a town of Germany, in the grand-duchy of Saxe-Weimar,
romantically situated on a hill 400 ft. above the Saale, on the railway
Grossheringen-Jena and 7 m. N.E. of the latter. Pop. 700. Dornburg is an
ancient town, but is chiefly famous for its three grand-ducal castles.
Of these, the Altes Schloss is built on the site of an imperial
stronghold (Kaiserpfalz), once a bulwark against the Slavs, often a
residence of the emperors Otto II. and Otto III., and where the emperor
Henry II. held a diet in 1005; the Neues Schloss in Italian style of
architecture, built 1728-1748, with pretty gardens. Here Goethe was
often a guest, "healing the blows of fate and the wounds of the heart in
Dornburg." The third and southernmost of the three is the so-called
Stohmannsches Rittergut, purchased in 1824 and fitted as a modern
palace.
