Chemists tell us that certain substances in the act of formation, which they call nascent substances, are extraordinarily active and potent, and it may be that ice in the same state has a special tenacity of texture which belongs to that state alone. I wish that I could have measured the thickness of that ice.

Science was making great strides. Claes found that the progress of chemistry had been directed, unknown to chemists themselves, towards the object of his researches.

"A note in the manuscript to my study of which, I owe, under God, the preservation of Carmina's life warned me that chemists, in the writer's country, had either refused to make up certain prescriptions given in the work, or had taken the liberty of altering the new quantities and combinations of some of the drugs prescribed.

To Lavoisier is usually attributed this test experiment; but the fact that the weight of a metal increases by calcination was established by earlier European experimenters, and, indeed, was well known to the Arabian chemists. Lavoisier, however, was the first to recognize its great importance. In his hands it produced a revolution in chemistry.

One theory contended that the stony masses had not actually fallen, but had been formed from the earth by the action of the lightning; but this contention was early abandoned. The chemists were disposed to believe that the aerolites had been formed by the combination of elements floating in the upper atmosphere.

But I am, I perceived, detaining you from your time of rest goodbye," and Barkovis was wafted back toward his mirrored globe. "What do you make of this chemical solution blood of theirs, Steve?" asked Nadia, watching the placidly floating form of the Titanian captain. "Not much. I may have mentioned before that there are one or two, or perhaps even three men who are better chemists than I am.

The chemists Alban and Vallet made a magnificent balloon for the Count, who went up many times in it, with several persons of all ranks. Already at St. Cloud, the Duke of Chartres, afterwards Philippe Egalite, had, on the 15th of July, 1784, made, with the Brothers Robert, an ascent which put their courage to terrible tests.

Stone had accompanied the trio, and his testimony, supported by two chemists, regarding the time required for aconitine poison to act, had gone far to weaken the detective's case against Rochester.

From purely morphological investigations, Turpin and Schwann, as we have seen, arrived at the notion of the fundamental unity of structure of living beings. And, before long, the researches of chemists gradually led up to the conception of the fundamental unity of their composition.

DR. GALL further gives the following directions, as a guide, to distinguish and determine the proportion of acids which a must should contain, to be still agreeable to the palate, and good: "Chemists distinguish the acid contained in the grape as the vinous, malic, grape, citric, tannic, gelatinous and para-citric acids.
