The up and down movement of the plug actuates a graving stylus or point through a lever, and engraves a copy of the original gelatine trace on the surface of a wax or gelatine plate overlying another barrel or drum, which revolves at a rate corresponding to that of the barrel at the transmitting station.
The diagnosis has to be made from solid or cystic tumours overlying the artery; from a "pulsating aorta"; and from spinal caries; much help is obtained by the use of the X-rays. The condition usually proves fatal, either by the aneurysm bursting into the peritoneal cavity, or by slow leakage into the retro-peritoneal tissue.
At the same time this descending water drifts along the bottom of the ocean troughs toward the equatorial realm. As this cold water is heavier than that which is of higher temperature and nearer the surface, it has no tendency to rise. Being below the disturbing influences of any current save its own, it does not tend, except in a very small measure, to mingle with the warmer overlying fluid.
His first glance brought me over to him as he exclaimed loudly. At the point just opposite the sore which he had observed on Virginia's forehead, and overlying the sella turcica, there was a peculiar spot on the radiograph. "Something in that mask has affected the photographic plate," he explained, his face now animated.
Considering that in the Uspallata range the lowest strata on the western flank lie unconformably on the clay- slate, as probably is the case with those on the eastern flank, whereas in the Cordillera all the overlying strata lie conformably on this formation: -considering that in the Uspallata range some of the beds, both low down and high up in the series, are marked with vegetable impressions, showing the continued existence of neighbouring land; considering the close general resemblance between the deposits of this range and those of tertiary origin in several parts of the continent; and lastly, even considering the lesser height and outlying position of the Uspallata range, I conclude that the strata composing it are in all probability of subsequent origin, and that they were accumulated at a period when a deep sea studded with submarine volcanoes washed the eastern base of the already partially elevated Cordillera.
He derived his name from the remarkable transparency of his deformed members to electric light, due to porosity of the bones and deficiency of the overlying tissues. The knees and elbows were completely ankylosed. Infantile spinal paralysis is often the cause of distressing deformities, forbidding locomotion in the ordinary manner.
They consist of blue clays with some subordinate layers of lignite, and exhibit a richer flora than the overlying Newer Pliocene beds, and one receding farther from the existing vegetation of Europe. They also comprise more species common to the antecedent Miocene period.
Go, watch the shadows of the vines swaying in the mulberry-trees from Epomeo's gales. Bind the ivy in a triple crown above Bianca's comely hair, and pipe not so wailingly to the Vikings of this frigid Norseland. But Italy, remember, my frigid Norseland has a heart of fire in her bosom beneath its overlying snows, before which yours dies like the white sick hearth-flame before the noonday sun.
From the manner in which the red clay fills up furrows in the underlying gravel, and is in some parts itself furrowed by the overlying gravel, whilst in other parts it either insensibly passes into, or alternates with, this upper gravel, we may infer several local changes in the currents, perhaps caused by slight changes, up or down, in the level of the land.
Third. Irregular subsidences then began, and occasionally partial failures of support, causing the bending and sometimes the engulfment of overlying masses both of the Chalk and drift, and causing the various dislocations above described and depicted.
