inexhaustible that science must retain its ascendency. Now, it is surely not unreasonable to surmise that there are limitations in the nature of the universe which must circumscribe the achievements of speculative research. Every astronomer knows that there was only one secret of the universe to be discovered, and that when Newton told it to the world the supreme triumph of astronomy was achieved. Whether Darwin or some one else shall have disclosed the other great mystery of the generation of life, it is none the less certain that all future triumphs will be insignificant by the side of the first luminous hypothesis. Chemistry rests, when all abatements have been made, on the atomic theory, and even if future investigation enables us to forecast with absolute precision what the result of combinations hitherto unattempted will be, so that we can calculate in the study what is now worked out gropingly in the laboratory, that discovery would hardly eclipse the merit of Dalton's contribution to science.[1] So it is in every department of research. Even the greatest men are little more than sagacious interpreters of thought and toil which others have expended obscurely. The discovery of a new metal, a new star, or a new species is now nothing to thrill us with wonder and awe. We know that it has been worked up to by former experiments or is the result of improved instruments, and is no more matter of wonder than that this year's best steamship should make a knot an hour more than was possible five years ago. Then again, not only is science ceasing to be a prophet, but in virtue of her very triumphs, precisely because her thoughts are passing into the life-blood of the world, is
- ↑ The late Professor H. J. S. Smith was inclined to think this possible and worth working for.
