In some of those birds which have a peculiarly harsh or trumpeting voice, the trachea is lengthened, forming loops which lie subcutaneously (capercally, curassow), or it enters and dilates the symphysis of the furcula (crested guineafowl); or, e.g.
He is chiefly occupied with the means whereby the unio mystica is to be attained, whereas Eckhart dwells on the union as an ever-present fact, and dilates on its metaphysical implications.
These equations were found by d'Alembert from two principles - that a rectangular canal, taken in a mass of fluid in equilibrium, is itself in equilibrium, and that a portion of the fluid, in passing from one place to another, preserves the same volume when the fluid is incompressible, or dilates itself according to a given law when the fluid is elastic. His ingenious method, published in 1752, in his Essai sur la resistance des fluides, was brought to perfection in his Opuscules mathematiques, and was adopted by Leonhard Euler.
The first vortex dilates and moves slower, while the second contracts and shoots through the first; after which the motion is reversed periodically, as if in a game of leap-frog.
In other Entoprocta the buds on a horseshoe retain a high degree of individuality, a shaped l o p h o - thread-like stolon giving off the cylindrical phore; stalks, each of which dilates at its end i, Ectocyst; into the body of a zooid.
Thoroughly rubbed into the skin alcohol dilates the bloodvessels and produces a mild counter-irritant effect.
As it dilates the blood-vessels of the skin it increases the subjective sensation of warmth.
By division of the egg-cell a mulberry-mass of embryonic-cells is formed (morula), which dilates, forming a one-celllayered sac (blastula).
Now we can see the reason for their administration, because the nitrous ether, consisting chiefly of ethyl nitrite, dilates the superficial vessels and thus allows greater escape of heat from the surface; while acetate of ammonia, by acting as a diaphoretic and stimulating the secretion of sweat, increases the loss of heat by evaporation.
The pack has the double effect of restraining his movements and thus lessening the production of heat, while at the same time it dilates the vessels of the skin and produces loss of heat.
So far is it from being an haemostatic that, if perfused through living blood-vessels, it actually dilates them.
The mouth leads into the oesophagus, which extends straight down the body nearly to the aboral end or " ampulla," where it dilates into a stomach, from which the ascending limb of the U-shaped alimentary canal passes directly to the anus.
