A second cave, nearly as celebrated as the former, and very near, is that which is named, after the unicorn, Enihornshæle, at the foot of the chateau of Scharzfels, in a part of the Electorate of Hanover which is named the Dutchy of Grubenhagen, and nearly upon the last southern declivity of the Hartz. It has also been described by Leibnitz, as well as by M. Deluc, in his Letters to the Queen of England. The entrance is 10 feet high, and 7 broad. We descend vertically 15 feet into a sort of vestibule, the roof of which lowers to such a degree, that, at the end of 60 feet, we are obliged to creep. After a long passage, we come to two other caves, according to Leibnitz; but Behrens adds three or four, and says, that, according to the country people, we might penetrate nearly two leagues.

Bruckmann, who gives a map of this cavern (Epistol. Itin. p. 34.), represents only five caves, arranged nearly in a straight line, and connected by extremely narrow passages. The second is the richest in bones; the third, which is the most irregular, has two small lateral caves; the fifth is the smallest, and contains a fountain. Of the bones which have been taken from it, some are in the possession of M. Blumenbach and other naturalists; and others have been figured by Leibnitz and Mylius. They belong to the bear, hyena, and tiger or lion genera.

The chain of the Hartz also presents some other caves of less celebrity, although of the same nature mentioned by Behrens in his Hercynia curiosa, namely,

The cave of Hartzburg, under the castle of the same name, above Goslar to the south. We do not know why Büsching disputes its existence. It is true that Behrens cites J. D. Horstius erroneously, for having seen bones of various animals taken from it; for Horstius speaks only (Obs. Anat. dec. p. 10.) of the cave of Scharzfels.

The cave of Ufftrungen, in the county of Stollberg, to the south of the castle of that name. It is named in the country Heim-knohle, or Hiding-hole. Behrens thinks that fossil bones might be found in it.

Another cave of the same neighbourhood, is named Diebsloch, Thieves’ Hole. Skulls have been found in it, which were supposed to be human.

We shall not speak here of those caves of the Hartz in which bones have not been discovered. And even those in which they have been found, are, at the present day, almost exhausted, it being only by breaking the stalactite that any can be obtained, so much of them had been taken away for selling as medicines.

The caves of Hungary come after those of the Hartz, with reference to the remoteness of the time at which they have been known. The first notice of them is due to Paterson Hayn, (Ephem. Nat. Cur. 1672, Obs. cxxxix. and cxciv.) Bruckmann, a physician of Wolfenbüttel, afterwards described them at length. (Epistola Itineraria, 77, and Breslauer Sammlung, 1725, First Trim. p. 628.) They are situated in the county of Liptow, on the southern declivities of the Carpathian mountains. They are known in the country by the name of Dragons’ Caves, because the people of the neighbourhood attribute to those animals the bones which occur in them, and with which they have been acquainted from time immemorial; but all those which have been figured by authors belong to the Bear family, and to the species which is named the Great Cave Bear (Grand Ours des cavernes).

The caves of Germany the richest in bones are those of Franconia, of which J. F. Esper, a clergyman of the country of Bayreuth, has given a very detailed description in a work, printed in French and German, entitled, Description des Zoolithes nouvellement decouvertes, &c. Nuremberg Knorr. 1774, folio, with 14 coloured plates, and in a memoir inserted among those of the Berlin Society of Naturalists, vol. ix. 1784, p. 56. Another description was afterwards given, under the title of Objets dignes de remarque des environs de Muggendorf, by J. C. Rosenmüller, folio, with coloured views, Berlin, 1804. And more lately, M. Goldfuss, at present Professor of Natural History at Bonn, and Secretary of the Academia Naturæ Curiosorum, has made them the subject of a particular work printed in 1810 in German, under the title of Environs of Muggendorf, in which he describes them with the greatest care, as well as the surrounding country, of which he gives a very correct topographical chart. A great part of these caves is situated in a small bailiwick, named Streitberg, which was formerly a dependence upon the country of Bayreuth, but was inclosed in that of Bamberg, and now forms part of the kingdom of Bavaria. The greatest number occur in a small peninsula, formed by the river of Wiesent, which falls into the Pegnetz, and belongs to the basin of the Main.
