Rh  1em  GLOBE-FISH or. By these names some sea-ﬁshes are known, which have the remarkable faculty of inflating their stomachs with air. They belong to the genera Diodon and Tetradon. Their jaws resemble the sharp beak of a parrot, the bones and teeth being coalesced into one mass with a sharp edge. In the Diodonts there is no inesial division of the jaws, whilst in the Tetrodonts such a division exists, so that they appear to have two teeth above and two below. By means of these jaws they are able to break ott‘ branches of corals, and to masticate other hard substances on which they feed. Usually they are of a short, thick, cyclindrical shape, with powerful ﬁns (ﬁg. 1).

Their body is covered with thick skin, without scales, but provided with variously formed spines, the size and extent of which vary in the different species. When they inflate their capacious stomachs With air, they assume a globular form, and the spines protrude, forming a more or less for- midable defensive armour (ﬁg. 2).

A ﬁsh thus blown out turns over and ﬂoats belly upwards, driving before the u ind and waves. Many of these ﬁshes are highly poisonous when eaten, and fatal accidents have occurred from this cause. It appears that they acquire poisonous qualities from their food, which frequently consists of decomposing or poisonous animal matter, such as would impart, and often does impart, similar deleterious qualities to other ﬁsh. They are most numerous between the tropics and in the seas con- tiguous to them, but a few species live in large rivers, as, for instance, the Tetrodon faka/ra, a ﬁsh well known to all travellers on the Nile. Nearly 100 different species are known.  GLOBIGERINA. See.  GLOGAU (sometimes called Gross or Great Glogau, to distinguish it from Klein or Little Glogau, in the govern- ment of Oppeln), is a fortiﬁed town of Prussia at the head of a Circle in the Lower Silesian government of Liegnitz, Situated partly on an island and partly on the left bank of the Oder, about 80 miles SE. of Frankfort. Among its more important buildings are the cathedral, in the Gothic style, and a castle in the Renaissance style, now used as a courthouse ; and it also possesses a new town-house, a synagogue, a poorhouse, an orphanage, a military hospital, two gymnasia, and several libraries. Situated as it is on a navigable river and at a junction of two or three railway lines, Glogau carries on an extensive trade, which is fostered by a variety of local industries, dealing with tobacco, beer, oil, sugar, vinegar, bone-meal, earthenware, &c. One of its publishing ﬁrms—that of Flemming & Company—has at- tained awide reputation for maps. In 1871 the population of Glogau, inclusive of the garrison, amounted to 18,266,— of whom 6039 were Roman Catholics and 947 Jews ; and in 1875 it was stated at 18,062.
