In connexion with the motions of the heart these things are further to be observed having reference to the motions and pulses of the arteries. At the moment the heart contracts, and when the breast is struck, when in short the organ is in its state of systole, the arteries are dilated, yield a pulse, and are in the state of diastole.
By turning the screws to which the pads are attached the desired amount of pressure can be applied to the arteries, and the apparatus can be worn for any length of time by the patient. Where, however, the headache is of manifestly nervous origin and uncomplicated by any especial circulatory derangements, I have never been able to achieve notable results with this method.
One of the temporal arteries was ligated, and the scalp cleansed and reapplied. The hanging ears and the skin of the forehead were successfully restored to their proper position. The patient had no bad symptoms and little pain, and the shock was slight. Where the periosteum had sloughed the bone was granulating, and at the time of the report skin-grafting was shortly to be tried.
It is now a narrow, dark, and dirty street; its south side is covered with quays and wharves; narrow lanes lead to ancient river stairs; its north side is lined with warehouses, the streets which run out of it are also dark and narrow lanes with offices on either side. It is no longer one of the great arteries of the City.
For instance, certain rhythms existing in music are identical with, or analogous to, the rhythm of our bodily movements under varying circumstances: we know alternations of long and short, variously composed regularities and irregularities of movement, fluctuations, reinforcements or subsidences, from experience other than that of music; we know them in connection with walking, jumping, dragging; with beating of heart and arteries, expansion of throat and lungs; we knew them, long before music was, as connected with energy or oppression, sickness or health, elation or depression, grief, fear, horror, or serenity and happiness.
In the Selachii an arterial cone is developed from the foremost end of the ventricle, as a special division, cut off by valves. On each side 5 to 7 arteries proceed from it. The junctures of the various aortic arches on the right and left are called the roots of the aorta.
Every time that the left ventricle, by contracting itself, chases the blood into the arteries, these, of which the tissue is very elastic, become distended all at once, and then contract again, repeating the process whenever a fresh gush of blood arrives, so that their movement is exactly regulated by the movement of the heart.
Here, at a later day, the same race chained the tyrant Ocean and his mighty streams into subserviency, forcing them to fertilize, to render commodious, to cover with a beneficent network of veins and arteries, and to bind by watery highways with the furthest ends of the world, a country disinherited by nature of its rights.
But always what answers the call is your mental experience, no less yours, no less wedded to your life, than the blood in your arteries; it cannot be that of any other. And the same is true, or nearly the same, respecting the most obvious outside matters. Suppose one to make merely this statement, I see a house.
They thus got to the street of the Sun one of the main arteries of the city cutting the Canopic way at right angles and they went down it towards the Gate of Helios in the south wall. The Serapeum lay to their right, several streets leading to it from the street of the Sun.
