Page 315 - The explanation which he gave was virtually as follows : — The rapid flow on the inner and strongly curved side of the bend piles up the water on the outer side by centrifugal force, so that near the concave bank it is nearly stationary, but elevated ; its energy there is potential, not kinetic. Now if the rapidity of flow were uniform from top to bottom the slope would be in equilibrium ; but owing to the retardation of the...

Page 321 - ... of theory is necessary to direct the observer. Though a man may begin to observe without any hypothesis, he cannot continue long without seeing some general conclusion arise ; and to this nascent theory it is his business to attend, because, by seeking either to verify or to disprove it, he is led to new experiments, or new observations. He is led also to the very experiments and observations that are of the greatest importance, namely, to those instantice crucis, which are the criteria that...

Page 98 - ... have begun to show themselves two sulci are gradually introduced upon either side, dividing the external portions of the volutions into three approximately equal divisions. The area between the umbilicus and the sulcus on each side is occupied by the nodes or plications, which die out as such toward the sulcus, bending sharply and strongly forward in so doing. At this point they degenerate into or are replaced by growth lines, which are continued across the ventral surface defined by the two...
