"So, sister, God to me is kind, Though sight to me He has not given; Ere long, disease its hand had laid He felt her warm tears on his face, "And you'll be there, kind Mary, too; He spoke no more, but sweetly smiled, Home Exercises.-1.

Hypothesis, an opinion held as accounting for some known facts. Vacuum, empty space. Germinate, to grow from a seed. Bucket, the part of a pump that works in the barrel. Venture, to try to do. power. Exploded, forced into THESE lessons have shown how necessary it is to observe fully and accurately, and further, how, by means of experiment, we may extend our range of observation. But in scientific inquiry we do not stop here. And partly, for this reason, we often want to know, not only what is, but also what is likely to be. And further, if every fact has to be observed in itself as such, we shall make but very slow advance. Thus, we will say that last year we sowed a bean, and there up sprang the bean plant, which bore a pod, and in it a bean seed very like the one we planted last year. We know that others have pursued a similar course with other plants and with a like result. Now, with these known facts, no one would sow a given seed and watch the result before he would venture to predict what would follow. He would say that the seed of any plant sown under favourable circumstances would, in each case, produce a plant similar to that from which the seed was raised. But how does he know this? Not from observation. The seed was never anything but seed. Not from experiment, he has as yet put it to no test. It is at present, then, only a hypothesis. Seeds have been observed to germinate and grow into plants corresponding to those from which they were produced, and, on this hypothesis he sows; and, as we know, in due course he reaps; for in this case, hypothesis has passed into known law. Let us take another case. You all know what happens when we take a jugful of water out of a pond. For the time being a hole is made in the water; but as soon as the jug is removed, the surrounding water fills up the space occupied by the jug, and presently all is level as before. Again; we all know something about the action of a common pump. By a proper arrangement of a barrel and a movable bucket, each with a valve fitted to it, we first pump the air out of the pipe and barrel, and having done this, the water from the spring below very soon follows. For ages, these and other similar facts were observed, and in due course men formed a hypothesis to account for them. And about three centuries ago the current hypothesis to account for such phenomena was, that "Nature abhors a vacuum;" or, in other words, they meant to say that, in the natural order of things, bodies always fill up void spaces. Now, since that time, men have observed more carefully, and have experimented more freely; and it is found that this hypothesis is not sound. For the water flows into the empty space by virtue of its fluidity and the law of gravitation. And in the second case, the water rises in the pump, not because Dame Nature abhors a vacuum, but because the pressure of the air having been removed from within the barrel, the pressure of air on the outside water forces it up the tube, where the corresponding pressure has been withdrawn. We have now the case of one hypothesis that has stood the test of repeated trials, and so has become law; and of another that would not stand the test, and is therefore but an exploded or abandoned hypothesis.
