Such a people, when they took to studying physical science, would be, and in fact were, incapable of Chemistry, Geognosy, Comparative Anatomy, or any of that noble choir of sister sciences, which are now building up the material as well as the intellectual glory of Britain.
First, it is universally conceded that the auriferous deposits remaining untouched are vastly in excess of those already found and worked. Second, all of my life I have made a profound study of geognosy and geotectonic geology. Now, it is not only the money; money I count as a rather questionable gift, anyway. But it is my own reputation.
If the government would order the Capitania-General of Caracas to be carefully examined during a series of years by men of science, well versed in geognosy and chemistry, the most satisfactory results might be expected. The description above given of the productions of Venezuela and the development of its coast sufficiently shows the importance of the commerce of that rich country.
This fossil does not exhibit those little streaks of quartz so common in the Lydian stone. It is found decomposed at its surface into a yellowish grey crust, and it does not act upon the magnet. In the study of formations, which is the great end of geognosy, the knowledge acquired in the old and new worlds should be made to furnish reciprocal aid to each other.
The phenomena of geognosy, particularly those which are connected with the stratification of rocks, and their grouping, are never solitary; but are found the same in both hemispheres.
From one of the ridges in the midst of the valley, a conical precipitous hill, called Lot, boldly stands up, and forms a most singular and conspicuous object. It is composed of phonolite, divided in one part into great curved laminae, in another, into angular concretionary balls, and in a third part into outwardly radiating columns. Seale in his Geognosy of the island.
Considerations on the aspect of a country are independent of those which indicate the nature of the soil, the heterogeneity of matter, the superposition of rocks and the direction and inclination of strata. In taking a general view of the geological constitution of a chain of mountains, we may distinguish five elements of direction too often confounded in works of geognosy and physical geography.
Notwithstanding the difference of composition in the recent lavas of the Peak, there is a certain regularity of position, which must strike the naturalist least skilled in geognosy. The great elevated plain of Retama separates the black, basaltic, and earthlike lava, from the vitreous and feldsparry lava, the basis of which is obsidian, pitch-stone, and phonolite.
He resigned his office and tramped with knapsack on back across the Alps. The habit of his mind was that of the naturalist-investigator. Geology, botany and zoology were his properties by divine right. These sciences really form one geognosy, or the science of the formation of the earth.
The task of science is, through geology, geognosy, mineralogy, geodesy, physical geography, meteorology, and other sciences to discover the physical, chemical, and mechanical causes of the earth’s evolution and their laws, and from the co-operation of these to interpret everything in detail and as a whole.
