الصفحة 57 - Could the young but realize how soon they will become mere walking bundles of habits, they would give more heed to their conduct while in the plastic state. We are spinning our own fates, good or evil, and never to be undone.
الصفحة 17 - Under our system the workman is told minutely just what he is to do and how he is to do it; and any improvement which he makes upon the orders given him is fatal to success.
الصفحة 23 - Such a surface might restrain diffusion, bank up osmotic pressure, restrict the movement of ions, accumulate electric changes, support a double electric layer, alter in shape and surfacetension with changes in difference of potential, alter in difference of potential with changes in surface-tension or in shape, or intervene as a membrane between dilute solutions of electrolytes of different concentration or colloidal suspensions with different sign of charge.
الصفحة 145 - So sunk, so rarely lifted save to meet Her children's? She moves slow; her voice alone Hath yet an infantine and silver tone, But even that comes languidly; in truth, She seems one dying in a mask of youth.
الصفحة 146 - Lies thy slaughtered father there. Weep not ; but when years are over, And thine arm is strong and sure, And thy foot is swift and steady On the mountain and the muir, Let thy heart be hard as iron. And thy wrath as fierce as fire, Till the hour when vengeance...
الصفحة 7 - I have recorded, and from those of previous workers, is that caffein increases the capacity for both muscular and mental work, this stimulating action persisting for a considerable time after the substance has been taken without there being any evidence, with moderate doses, of reaction leading to diminished capacity for work, the substance thus really diminishing and not merely obscuring the effects of fatigue.
الصفحة 68 - ... the animels, and then ran five or six hundredd yards iutoo the jungle. 3. After varius false allarms, aud vane endevors to discuvor the obgects of our chace, the colector went into the jungle, and Captin B and myself into bed of the stream' where we had sen the traks; and here it was evedent the elaphents had passed to and fro. Disapointed and impasient, we allmost determened to giv up the chace and go home; but shots fird just before us reanimated us, aud we proceded, and found the collecter...
الصفحة 58 - The standard deviation, mathematically, is the square root of the average of the squares of the deviations of the individual cases from the mean.
الصفحة 23 - ... electrolytes of different concentration or colloidal suspensions with different sign of charge. It would be a mechanism where nervous conduction, especially if predominantly physical in nature, might have grafted upon it characters just such as those differentiating reflex-arc conduction from nerve-trunk conduction. For instance, change from reversibility of direction of conduction to irreversibility might be referable to the membrane possessing irreciprocal permeability.
الصفحة 143 - In a rude state of society men are children with a greater variety of ideas. It is therefore in such a state of society that we may expect to find the poetical temperament in its highest perfection.
