nd in the vicinity of Cuevas de Vera the remains of elephants have been found, isolated and distributed in different directions, proving the existence of a more tropical climate in former times than now prevails in those districts. * * * * * In the Paris ACADEMY OF SCIENCES an extended Report was read at a recent meeting from a committee on M. ROCHET D'HERICOURT'S third journey in Abyssinia, in the northern part. He started in 1847, and returned in 1849. In Geography he determined directly, by observation of the meridian heights of the sun, the latitude of a large number of geographical points in Egypt, in Arabia Petraea, along the coasts of the Red Sea, and in the north of Abyssinia. His meteorological observations were constant, and are pronounced especially exact. So, those of the magnetic inclination. The results are furnished in the Report. He attended closely and successfully to the geology of the regions which he traversed. The geological constitution of Abyssinia is now made known over the greater part of its surface. The herbary which the traveller brought to the Museum of Natural History, consists of 150 species, the most of them, however, of plants already known. Three new ones are described. He succeeded in getting home a sheep of Abyssinia, remarkable for the long hairs of its fleece. Some of his specimens of fish are new. Much attention is given to his new species of _Epeira_, or silk-spider. At the sight of the silk which forms the web of the insect, he conceived the hope that it might be turned to account for the silk-manufacture. It is very fine and soft, long and firm enough, and of a beautiful yellow color. This spider inhabits the large trees, shrubbery, and hedges, and extends its webs to the neighboring habitations; and the webs are nearly all more than a yard in diameter. The quantity is prodigious. "M. d'Hericourt," says the Report, "like every person who has attempted tissues with spiders' webs or cocoons, has not sufficiently regarded the difficulty of domesticating them, as is done with the silk-worm, in order to multiply them adequately, and provide them with such insects of prey, or sufficient nourishment." The Committee proposed the formal thanks of the Academy to the traveller, for the scientific harvest of his new journey, and an expression of the interest felt in the speedy publication of his narrative. * * * * * SHOOT
