第 116 頁 - Hence appear the many mistakes which have made learning generally so unpleasing and so unsuccessful ; first, we do amiss to spend seven or eight years merely in scraping together so much miserable Latin and Greek, as might be learned otherwise easily and delightfully in one year...
第 119 頁 - In the state of decerebrate rigidity, the ordinarily observed reflexes of the body become profoundly altered, and a study of the normal and abnormal reflexes led him to the observation that contraction of one muscle is commonly associated with inhibition of its antagonist. Upon this he formulated the law of the reciprocal action of antagonistic muscles, which is now accepted as of fundamental importance in the coordination of muscular movement. A further study of reflex actions led him to lay down...

The numbers of earthquakes in each of these periods taken in the order named were 211, 307, and 232, that is to say, during the period when the change in direction...

They do not hear her most imperative warnings, and can only get on haltingly in their everyday intercourse with the natural forces to which their lives are subjected, by means of the arbitrary signs of empirical custom. The recent introduction of some amount of science-teaching in our higher schools is quite inadequate, alike in kind and in degree. It can be only through a reform of the scheme of their examinations by the Universities, that we can hope to see Science take...

If we take a chart showing the varying position of our earth's North Pole in relation to its mean position, we see that the secular movement of the pole is by no means always uniform. Although it may at times follow a path about its mean position which is approximately circular, at other times there are comparatively sharp changes in direction of motion which may even become retrograde. If now on a chart of this description we mark the timepositions of very large earthquakes, we find...

第 374 頁 - February 2 announced that cables between Jamaica and Puerto Rico had been interrupted, and on later dates it was reported that severe shocks had been felt among the West Indian Islands, that six or seven submarine cables had been broken, and that Mte. Pele'e and La Soufriere, in St. Vincent, were again active.

However keen in vision, the eyes see little without training in observation by the subtle exercise of the mind behind them. From the humblest weed to the stars in their courses, all Nature is a great object lesson for the acquirement of the power of rapid and accurate noting of minute and quickly changing aspects.
