THIS part of the report of the Isis Natural History Society of Dresden contains as usual a great number of interesting notices in all departments of natural history, the most important being on botanical subjects, namely, the commencement of a prodromus of the Lichens of Saxony, Thuringia, and Northern Bohemia, by Dr. L. Rabenherst, and the conclusion of a synopsis of the Coniferæ, by M. Laessig. In the latter, diagnoses of the families and genera are given, and the general characters and geographical distribution of the species are indicated. In the continuation of a lecture on extinct mammalia, Dr. Günther noticed the following species:—Cants familiaris fossilis, C. spelæus (= C. lupus), C. vulpes fossilis, Hyæna spelæa, Felis spelæa, F. antiqua, Cuv., F. minuta fossilis, Wagn., F. aphanista, and ogygia, Kaup, and some species of Mustela. In a paper on recent explorations for rock salt in Prussia, M. Otto noticed the occurrence of a vast bed of that mineral near Sperenberg, where a boring has been carried down 2,270 feet, of which 1,920 feet is through a salt bed. The boring has probably nearly reached the bottom of the deposit, as the material brought up now contains much anhydrite. Near Segeberg, in Holstein, a deposit of salt has been met with at a depth of 400 feet.
