Yet one other point about the views of Galen. He thought that both the contractions and dilatations of the heart what we call the 'systole' or contraction of the heart, and the 'diastole' or dilatation Galen thought that these were both active movements; that the heart actively dilated, so that it had a sort of sucking power upon the fluids which had access to it.
Of these four processes two are dilatations, one when the lungs attract the air, another when the breast dischargeth itself of it upon the lungs; two are contractions, one when the breast draws into itself the air, the second when it expels this which was insinuated into it.

Listen to the heart-beat of some friend. Experiment 102. To show how the pulse may be studied. "The movements of the artery in the human body as the pulse-wave passes through it may be shown to consist in a sudden dilatation, followed by a slow contraction, interrupted by one or more secondary dilatations.
If we are once able to restrain the offices of human life within their just and natural limits, we shall find that most of the sciences in use are of no great use to us, and even in those that are, that there are many very unnecessary cavities and dilatations which we had better let alone, and, following Socrates' direction, limit the course of our studies to those things only where is a true and real utility: "Sapere aude; Incipe; Qui recte vivendi prorogat horam, Rusticus exspectat, dum defluat amnis; at ille Labitur, et labetur in omne volubilis oevum."
The Frenchman, having swallowed the first spoonful, made a full pause, his throat swelled as if an egg had stuck in his gullet, his eyes rolled, and his mouth underwent a series of involuntary contractions and dilatations.
For hence all the arteries of that organism draw their life, and on the systole and diastole of the Base, on the contractions and dilatations of its auricles and ventricles, the Army depends for its circulation. To and from the Base come and go in endless tributaries men, horses, supplies, and ordnance. The Base feeds the Army, binds up its wounds, and repairs its wastage.
It is convenient to describe in this section also certain conditions in which there is an abnormal communication between an artery and a vein arterio-venous aneurysm. In this class are included such dilatations as result from weakening of the arterial coats, combined, in most cases, with a loss of elasticity in the walls and increase in the arterial tension due to arterio-sclerosis.
This period was followed by other dilatations of the same veins, and the introduction of other sets of mineral deposits, as well as of pebbles of the basaltic lavas of Auvergne, derived from superficial alluviums, probably of Miocene or even Older Pliocene date.
