The writer has seen young boys, of eight and ten years of age, gathering and cleaning shells from rivers, and collecting plants and mineralogical specimens, with a delight bordering on ecstasy; and there are few, if any, who by proper influences would not find this a source of ceaseless delight and improvement.
If one really had, like the owners of estates, to live in the country, it would be well to supply one's self with a geological, mineralogical, entomological, or botanical hobby; but a sensible man doesn't give himself a vice merely to kill time for a fortnight. The noblest estate, and the finest chateaux soon pall on those who possess nothing but the sight of them.
This was done in the mineralogical nomenclature proposed by Professor Mohs. “The names framed by him were not composed of two, but of three elements, designating respectively the Species, the Genus, and the Order; thus he has such species as Rhombohedral Lime Haloide, Octohedral Fluor Haloide, Prismatic Hal Baryte.” The binary construction, however, has been found sufficient in botany and zoology, the only sciences in which this general principle has hitherto been successfully adopted in the construction of a nomenclature.
The visitor has now examined the contents of the second room; the fossil tortoises and great wingless birds; the mineral combinations nearly all of which are useful to man; and the way westward may be resumed to the third department of the northern mineralogical gallery. In the wall cases of this room are deposited some of the most interesting
A few days after this conference Pepe left Puerto Real. He had refused, some months before, a commission from the government to survey, in its mineralogical aspects, the basin of the River Nahara, in the valley of Orbajosa; but the plans to which the conference above recorded gave rise, caused him to say to himself: "It will be as well to make use of the time.
Why he had selected a bulky semifreighter like the Queen for a mineralogical survey jaunt to a lifeless little sun system far beyond the outposts of civilization was a point he didn't discuss. Gefty, needing the charter money, had restrained his curiosity. If Maulbow wanted only a pilot and preferred to do all the rest of the work himself, that was certainly Maulbow's affair.
"There," said Monsieur Becker, pointing to a long shelf against the wall between the stove and the window on which were ranged books of all sizes, "behold him! here are seventeen works from his pen, of which one, his 'Philosophical and Mineralogical Works, published in 1734, is in three folio volumes.
When we see, as is so often the case, a formation composed of beds of different mineralogical composition, we may reasonably suspect that the process of deposition has been much interrupted, as a change in the currents of the sea and a supply of sediment of a different nature will generally have been due to geographical changes requiring much time.
Fusus, very imperfect, somewhat resembling F. subreflexus of Navidad, but probably different. 3. Venus, fragments of. Sailing northward from Valdivia, the coast-cliffs are seen, first to assume near the R. Tolten, and thence for 150 miles northward, to be continued with the same mineralogical characters, immediately to be described at Concepcion.
There are the varieties of three minerals, which are very commonly met with in greater or less abundance in mineralogical trips: they are of calcite, steatite, and quartz. They occur in so many modifications of form, color, and condition that one might speedily form a cabinet of these, if they were taken when met with, and imagine it to be of great value. The first of these is calcite.
