These alcoves are formed by racks extending from floor to ceiling, fitted with shelves, except on two sides of both galleries, where they are formed by a series of glass-fronted cabinets containing extensive collections of curious and beautiful mineralogical and geological specimens, among which is the notable Tiffany-Kunz collection of minerals acquired by Edison some years ago.
In addition to the shops and machine rooms, there are well furnished cabinets of geological and mineralogical specimens, chemical laboratories for assaying and metallurgy, stamp mill, furnaces, etc., and, in fact, every known vehicle for practical instruction. The school of architecture prepares students for the building profession.
Still more recent streams of lava have been erupted from the scattered cones, such as Red and Signal Post Hills. The upper strata of the square-topped hills are intimately related in mineralogical composition, and in other respects, with the lowest series of the coast- rocks, with which they seem to be continuous.
He had laid aside for this purpose part of his salary as tutor, and was permitted, from 1810 to 1812, to complete in Gottingen his astronomical and mineralogical studies. Yet the wish to try his powers as a pedagogue never deserted him; and when, in 1812, the position of teacher in the Plamann Institute in Berlin was offered him, he accepted it.
As it is ascertained that mines of gold, silver, copper, and quicksilver exist in New Mexico and California, and that nearly all the lands where they are found belong to the United States, it is deemed important to the public interest that provision be made for a geological and mineralogical examination of these regions.
Gillies' account, this gypseous or cretaceo-oolitic formation extends as far south as the Pass of Planchon, and I followed it northward at intervals for 500 miles: judging from the character of the beds with the Terebratula aenigma, at Iquique, it extends from four to five hundred miles further: and perhaps even for ten degrees of latitude north of Iquique to the Cerro Pasco, not far from Lima: again, we know that a cretaceous formation, abounding with fossils, is largely developed north of the equator, in Colombia: in Tierra del Fuego, at about this same period, a wide district of clay-slate was deposited, which in its mineralogical characters and external features, might be compared to the Silurian regions of North Wales.
In order that the situation and character of the principal mineral deposits in California may be ascertained, I recommend that a geological and mineralogical exploration be connected with the linear surveys, and that the mineral lands be divided into small lots suitable for mining and be disposed of by sale or lease, so as to give our citizens an opportunity of procuring a permanent right of property in the soil.
The geographical and geological position of every ore-bank in the country, which has been opened and worked, is fully described, with many details of the peculiar properties, mineralogical associations, and history of each bed or mine.
It was curious to notice then the little differences that had come to things with this substitution. To borrow an image from my mineralogical days, these Jews were not so much a new British gentry as "pseudomorphous" after the gentry. They are a very clever people, the Jews, but not clever enough to suppress their cleverness. I wished I could have gone downstairs to savour the tone of the pantry.
Where the so-called beds are not very thick and of widely different mineralogical composition from each other, I do not think that there is any difficulty in supposing that they have originated in an analogous manner with the separate folia. We should bear in mind what thick strata, in ordinary sedimentary masses, have obviously been formed by a concretionary process.
