The latter illustration is one the validity of which appeals as forcibly to the physicists of to-day as it did to Hero. The same is true of the argument drawn from the compressibility of gases. Hero has evidently made a careful study of this subject.
The pulse is slow, the apex of the rise of the sphymographic arterial tracing is more or less sustained and rounded, and the rise is much less than normal. If this lesion occurs in old age, there is general arterial disease present, and the tension and compressibility of the arteries vary, depending on how much they are hardened.
The terms frequent and infrequent refer to the number of pulse beats in a given time; quick and slow to the length of time required for the pulse wave to pass beneath the finger; large and small to the volume of the wave; hard and soft to its compressibility; and intermittent to the occasional missing of a beat.
There is unquestionably a "union limit" between mobility and compressibility, and unless this limit is passed, mobility holds sway and prevents condensation or compression of the air; but when this limit is passed by the exercise of sufficient energy, then compression of the air results.
In spite of the village elder's assertions about the compressibility of hay, and its having settled down in the stacks, and his swearing that everything had been done in the fear of God, Levin stuck to his point that the hay had been divided without his orders, and that, therefore, he would not accept that hay as fifty loads to a stack.
Perkins, the American, who has tried experiments on the compressibility of water, the results of which have astonished all the scientific world. Wollaston, as Mr. Ralston affirms, has verified and warrants the truth of these experiments, which have not yet been published. The most wonderful part appeared to me incredible: under a great degree of compression the water, Mr.
These researches have dealt with a certain number of different bodies. Those relating to carbonic acid and ethylene take in the critical point. Others, on hydrogen and nitrogen, for instance, are very extended. Others, again, such as the study of the compressibility of water, have a special interest, on account of the peculiar properties of this substance.
The rings must obviously be fitted over a boss upon the back of the valve; and between the rings, which are of brass, a gasket ring is interposed to compensate by its compressibility for any irregularity of pressure, and each of the bolts is provided with a ratchet collar to prevent it from turning back, so that the engineer, in tightening these bolts, will have no difficulty in tightening them equally, if he counts the number of clicks made by the ratchet.
After spending some time in Tuskegee and diligently applying myself, I was much gratified to find that I was able to pass the State examination for a second-grade certificate, and to teach, during the vacation period, the very school in which I had so long before learned to spell "horseback" and "compressibility." I spent four years in the Tuskegee Institute, graduating with the class of 1888.
The cohesive power of liquids is overcome by heat as well as that of solids, only to a much greater degree, for under it they assume a new form, acquire new properties, and expand immensely in volume. They pass into the form of vapour, occupy a thousand times larger area, and possess an elasticity of compressibility and expansibility they were destitute of before.
