This lecture did not disappoint the expectations of those familiar with the subject of the discourse, which, considering the difficulty of restating familiar historical facts in such a manner as to clothe them in a garb of originality, is high praise. Many, however, found great difficulty in hearing the speaker at the back part of the hall, and some left the room on that account. This was unfortunate, as the lecture will scarcely be exceeded in interest by any subsequent one of the course. The speaker said that "In all modern history, interference with science in the supposed interest of religion--no matter how conscientious such interference may have been--has resulted in the direst evils both to religion and science, and _invariably_. And on the other hand all untrammeled scientific investigation, no matter how dangerous to religion some of its stages may have seemed, temporarily, to be, has invariably resulted in the highest good of religion and science. I say _invariably_--I mean exactly that. It is a rule to which history shows not one exception. It would seem, logically, that this statement could not be gainsaid. God's truth must agree, whether discovered by looking within upon the soul or without upon the world. A truth written upon the human heart to-day in its full play of emotions or passions, cannot be at any real variance even with a truth written upon a fossil whose poor life was gone millions of years ago. And this being so, it would also seem a truth irrefragable; that the search for each of these kind of truths must be followed out in its own lines, by its own methods, to its own results, without any interference from investigators along other lines by other methods. And it would also seem logically that we might work on in absolute confidence that whatever, at any moment, might seem to be the relative positions of the two different bands of workers, they must at last come together, for truth is one. But logic is not history. History is full of interferences which have cost the earth dear. Strangest of all, some of the most direful of them have been made by the best of men, actuated by the purest motives, seeking the noblest results. These interferences and the struggle against them make up the warfare of science. One statement more to clear the ground. You will not understand me at all to say that religion has done nothing for science. It has done much for it. The work of Christianity has been mighty indeed. Through these 2,000 years it has undermined servitude, mitigated tyranny, given hope to the hopeless, comfort to the afflicted, light to the blind, bread to the starving, life to the dying, and all this work continues. And its work for science, too, has been great. It has fostered science often and developed it. It has given great minds to it, and but for the fears of the timid its record in this respect would have been as great as in the other. Unfortunately, religious men started
