We also caught a minute fish, 0.6 inches in length; a minute species of nautilus, blue, marked with striae, or grooved, and thus different from what we caught on the 15th; a shrimp-like species of animal 0.5 inches in length; the lower part of a species of Diphyes, which had been caught on the 12th and 13th of November 1837; some minute animals, appearing to be the young of the larger species of Velella which we had taken; they were, like this animal, at first blue, but turned red soon after being put into spirits; also a very minute pale blue species of nautilus, I think the young of the kind we caught on the 15th July.
Buckland published in 1842 his reasons for believing that the Snowdonian mountains in Caernarvonshire were formerly covered with glaciers, which radiated from the central heights through the seven principal valleys of that chain, where striae and flutings are seen on the polished rocks directed towards as many different points of the compass.
If, by the aid of the microscope, we examine a very fine section of muscle taken from a person in good health, we find the muscles firm, elastic and of a bright red color, made up of parallel fibres, with beautiful crossings or striae; but, if we similarly examine the muscle of a man who leads an idle, sedentary life, and indulges in intoxicating drinks, we detect, at once, a pale, flabby, inelastic, oily appearance.
Then the syenite or granite seemed as if it had been melted, for it was all in striae, which striae, as they do elsewhere, run east and west. With the change in geological structure we get a different vegetation. Instead of the laurel-leaved trees of various kinds, we have African ebonies, acacias, and mimosae: the grass is shorter and more sparse, and we can move along without wood-cutting.
In all countries the fundamental rock on which the boulder formation reposes, if it consists of granite, gneiss, marble, or other hard stone capable of permanently retaining any superficial markings which may have been imprinted upon it, is smoothed or polished, and exhibits parallel striae and furrows having a determinate direction.
The first actual inventor and constructor of an achromatic telescope was Chester Moor Hall, who was not in trade, and did not patent it. Towards the close of the eighteenth century a Swiss named Guinand at last succeeded in producing larger flint-glass discs free from striae.
The walls of these cuttings are covered with parallel striae, sometimes horizontal, sometimes slanting to the left, and sometimes to the right, so forming lines of serried chevrons framed, as it were, between grooves an inch, or an inch and a half, in width, by nine or ten feet in length.
The rock on which the boulder formation reposes, if it consists of granite, gneiss, marble, or other hard stone, capable of permanently retaining any superficial markings which may have been imprinted upon it, is usually smoothed or polished, like the erratics above described, and exhibits parallel striae and furrows having a determinate direction.
The furrows of these environing attempts show themselves distinctly, bending to the incline as they trench upon it; mounting in steeper curves, till the steepness baffles them, and their parallel threads show like the striae of waves pausing on the curl.
The faidon drew back toward them until it was actually touching the projector, and eddy currents and striae became visible in the mass about them as their progress grew slower and slower. "'Smatter? Something gone screwy?" demanded Seaton. "Not at all, everything is working perfectly.
