The Glands Regulating Personality The slow bending of the valve from the weight of particles of glass and even of box-wood, though largely supported by the water, is, I suppose, analogous to the slow bending of colloid substances. Insectivorous Plants This displacement would appear to indicate a difference of electric potential between the molecules of the colloid and those of the solvent. The Mechanism of Life A rapid journey home via Brindisi might have rattled my brains back into the colloid state in which they were when I left England. Life and Letters of Thomas Henry Huxley — Volume 2 The method is good in two respects: the absence of contact between the protective and protected surfaces and the colloid nature of the composition used. The Dream Doctor Closed spherules lined by a single layer of cells enclosing a gelatinous material known as colloid, which stains deeply with acid dyes, comprise the units of its architecture. The Glands Regulating Personality If, however, the blood does not return for four or more seconds, it is a sign that the capillary circulation is obstructed by colloid uric acid occlusion. Nature Cure The matter of which a living organism is constituted consists essentially of certain solutions of crystalloids and colloids. The Mechanism of Life Captain Hodgson opens the underbody colloid, swings the heavy pithing-iron out of its rack which in liners is generally cased as a smoking-room settee, and at two hundred feet releases the catch. Actions and Reactions It is also known that some of these acids, which were called long ago by Thenard azohumic, are enabled to dissolve colloid silica in proportion to the nitrogen which they contain. The formation of vegetable mould through the action of worms, with observations on their habits Some cases seem to have had their origin in overdosage with thyroid extract in too vigorous an attempt to cure a colloid goiter. Origin and Nature of Emotions These colloid substances occlude the minute excretory ducts in liver, spleen, kidneys and other organs, interfering with their normal functions and causing the retention of morbid matter in the system. Nature Cure Finally, it would seem that a colloid of one of the albuminoid groups is a necessary constituent of every living being. The Mechanism of Life The bow colloid is unshuttered and Captain Purnall, one hand on the wheel, is feeling for a fair slant. Actions and Reactions Until recently it was generally believed that diffusion took place in colloids and plasmas just as in pure water. The Mechanism of Life Iodin is stored in the colloid lacunae of the thyroid and, in combination with certain proteins, is the active agent of the thyroid. Origin and Nature of Emotions When a solute is introduced into a colloidal solution, the greater the concentration of the colloid the slower will be the diffusion. The Mechanism of Life Solutes, or substances capable of solution, may be divided into two classes—substances which are capable of crystallization, or crystalloids; and those which are incapable of crystallization, the colloids. The Mechanism of Life Captain Hodgson opens the great colloid underbody porthole through which I watch over-lighted London slide eastward as the gale gets hold of us. Actions and Reactions Living beings are but solutions of colloids and crystalloids, and their tissues are built up by the aggregation of these solutes. The Mechanism of Life If the thyroid cannot endure the strain, it undergoes hyperplasia, which in turn may result in a colloid goiter or in exophthalmic goiter. Origin and Nature of Emotions There is no real difference between the passage of a solution through an osmotic membrane and its diffusion through a colloid. The Mechanism of Life After death the colloids which have constituted the form of the living thing pass from their liquid state as "sols" into their coagulated state as "gels." The Mechanism of Life Her underbody colloid is open land her transporter-slings hang down like tentacles. Actions and Reactions The liner cheers hollowly above us, and we see the passengers' faces at the saloon colloid. Actions and Reactions He opened the colloid in that heavenly stillness and mopped his face. Actions and Reactions Then the Sun rises and through the colloid strikes out our lamps.
