He may have his bad points I'll admit he has but compared to all the little men his vision is wide and it goes deep. And if they'll only leave him alone and give him a chance, he'll take me and the other engineers, and the chemists and doctors and lawyers, and he'll make a world he's doing it now where ignorance and poverty will in time be wiped completely out."

We have found that the purest air and the purest water contain the largest proportion of oxygen; and it is this that vitalizes both food and, through food, the blood. To nourish this body, then, demands many elements; and to study these has been the joint work of chemists and physiologists, till at last every constituent of the body is known and classified.

The United States can reach that position and maintain it, and I believe that we are going to get such encouragement from the War Department that we can do it. I feel sure that the army appreciates the value of chemical warfare, and that it appreciates also the value of the chemists to chemical warfare.

Chemists have calculated how long it would take the ocean, which was originally fresh water, to take up from the rocks and rivers the salt which it contains to-day; Professor Joly has on this ground assigned a hundred million years since the waters first descended upon the crust.

President Boon not only submitted the specimens of ore-bearing rock which he had brought from the mine to careful analysis, but also appealed to several of the greatest living chemists and mineralogists to aid him; but they were all equally mystified. The green substance contained in the ore, although differing slightly from ordinary chrysolite, answered all the known tests of that mineral.

But, as to reading them after I had got them, I might as well have copied the Chinese inscriptions of an immense collection of tea-chests, or the golden characters on all the great red and green bottles in the chemists' shops! There was nothing for it, but to turn back and begin all over again.

The German chemists found that alizarine produced from madder in undergoing certain treatment gave a substance identical with anthracine, one of the constituents of coal tar, and in 1869 the same chemists announced to the world that they had accomplished the synthesis of alizarine from anthracine. The effect of this discovery was to throw madder out of cultivation. Mr.

The same discovery fixed the attention of chemists upon hydrogen as an important element in acids; and more recent discoveries having led to the recognition of its presence in sulphuric, nitric, and many other acids, where its existence was not previously suspected, there is now a tendency to include the presence of this element in the connotation of the word.

Here under almost impossible conditions there were performed a large volume of routine biological and chemical work, and a considerable amount of research, the results of which proved to be of far-reaching importance. With the employment of the first chemists and bacteriologists there arose a class of questions which I determined to settle once for all.

In one was a sticky black fluid; in the other, something as clear as water. "We are chemists, you see," the red-nosed man explained to Bodlevski with a grin, and then added: "Finch! on guard!" A young man, who had been lolling on a couch in the corner, rose and took up a position outside the door.
