Not only are some sets of striae not parallel to others, but the clay and rubbish between the walls, when squeezed or rubbed, have been streaked in different directions, the grooves which the harder minerals have impressed on the softer being frequently curved and irregular. Faults and denuded coal-strata, Ashby de la Zouch.
The shell is very different from those of the other nautili in being much more deeply indented with circular striae. July 18. South latitude 19 degrees 49 minutes; west longitude 3 degrees 10 minutes 15 seconds. We have lately caught several specimens of Creseis.
These marks are more clearly seen on the outer portion of the base of the wings, and on the innerside towards the middle and apex, and they are produced by striae and markings which are very common in allied species, but which are here modified and strengthened so as to imitate more exactly the venation of a leaf.
The bottoms of the main valleys, once grooved and planished like the glacier pavements of the Sierra, lie buried beneath sediments and detritus derived from the adjacent mountains, and now form the arid sage plains; characteristic U-shaped canyons have become V-shaped by the deepening of their bottoms and straightening of their sides, and decaying glacier headlands have been undermined and thrown down in loose taluses, while most of the moraines and striae and scratches have been blurred or weathered away.
The fine ribs that cross the whorls are not present on the wings, nor on the back; they are nodulated at their decussation with the raised striae. The wing-like varices of the whorls overlap each other alternately on each side of the shell. The only species to which it has affinity is the R. pulchra. Scalaria jukesiana. Tab. 3 fig. 7. Long. 13, Diam. max. 14, apert 3 mill.
The moving ice may sometimes cross even at right angles deep narrow ravines, or the crests of buried ridges, on which last it may afterwards seem strange to detect glacial striae and polishing after the liquefaction of the snow and ice has taken place.
On the inspection of the abdomen of a pregnant woman there will be noticed a brown line which extends from the umbilicus to the pubes, and all over the surface the presence of striae, or long purple grooves, due to the distention of the abdomen; on the sides of the abdomen and down the thighs, red, blue, or white markings, like cicatrices, may be seen. Quickening.
Separated by as wide an interval as they are, we shall yet find, if we look closely, in each case the same pathetic tokens of the still uneliminated striae of our poor humanity. The woman is not an old woman, for she has a "small young" family, which, had she lived, might have been increased: notwithstanding which, she has suffered from hemiplegia, "partial paralysis."
The surface striae of Pupa vetusta, when magnified 50 diameters, present exactly the same appearance as a portion corresponding in size of the common English Pupa juniperi, and the internal hexagonal cells, magnified 500 diameters, show the internal structure of the fossil and recent Pupa to be identical. In 1866 Dr.
As at Chilolé hill, we have igneous rocks, apparently trap, capped with masses of beautiful white dolomite. We still ascend in altitude as we go westwards, and come upon long tracts of gneiss with hornblende. The gneiss is often striated, all the striae looking one way sometimes north and south, and at other times east and west.
