Page xiii - Its subject-matter is a large moiety of the universe — its position is midway between the physico-chemical and the social sciences. Its value as a branch of discipline is partly that which it has in common with all sciences — the training and strengthening of common sense; partly that which is more peculiar to itself — the great exercise which it affords to the faculties of observation and comparison : and, I may add, the exactness of knowledge which it requires on the part of those among its...

Page 482 - ... most urgent need has now become, not more virgin soils on which to employ its slaves, but more slaves for the cultivation of its virgin soils. The important bearing of this change on the views of the Slave Power will hereafter be pointed out : for the present, it is sufficient to call attention to the fact.

Page 248 - AgN'O8 and then washed with cold water to remove the silver not in combination with gelatin. The gelatin was liquefied, brought to a 1 per cent solution, and the pH was determined. The solutions were then poured into testtubes and exposed to light. In about half an hour the gelatin of pH>4.7 was dark while the gelatin of pH 4.7 or less remained permanently clear though exposed to light for over a year. The pH of each gelatin solution is marked at the head of each test-tube. (After J. Loeb, Proteins...
Page 356 - The kneejerk is increased and diminished by whatever increases and diminishes the activity of the central nervous system as a whole." This general fact is supported, especially as regards mental activity, by observations on other similar mechanisms, — such, for instance, as the condition of the nervous centers controlling the bladder. Use of the Knee-jerk and Spinal Reflexes as Diagnostic Signs.
Page 145 - These are the lowering of vapor pressure, the elevation of the boiling point and the lowering of the freezing point of solutions compared with pure solvents.
