Two members of the Academy of Sciences taught him chemistry, so that he might be exact in his representation of Claes' experiments; and he read Berzelius into the bargain. Moreover, he had revised and modified the proofs of the novel no fewer than a dozen times. As Werdet tells, the real work of composition, with Balzac, hardly commenced until he had a set of galley proofs.
Pure gold is generally found in separate crystals or grains, but the metal is mostly found combined with other substances. It is alloyed, for manufacturing purposes, with copper and silver. Half of the third case, and cases 4, 5, and 6 in this room, are covered with various electro-negative metals and metalloids, classed according to the system laid down by Berzelius.
But an analogy is not an explanation, and why a few drops of yeast should change a saccharine mixture to carbonic acid and alcohol, a little leaven leavening the whole lump, not by combining with it, but by setting a movement at work, we not only cannot explain, but the fact is such an exception to the recognized laws of combination that Liebig is unwilling to admit the new force at all to which Berzelius had given the name so generally accepted.
Linnaeus, Berzelius, and others will materially assist him in grasping at the mysteries of animated creation; and if he be of a poetical turn, he can enjoy Belman in the unadulterated Scandinavian metre. For me, however, the public museums and libraries possessed only an external interest.
This simple system soon gained general acceptance, and with slight modifications it is still universally employed. Every school-boy now is aware that H2O is the chemical way of expressing the union of two atoms of hydrogen with one of oxygen to form a molecule of water. But such a formula would have had no meaning for the wisest chemist before the day of Berzelius.
"Selenium," went on Tom, "was discovered in 1817, by J. J. Berzelius, and he gave it that name from the Greek word for moon, on account of selenium being so similar, in some ways, to tellurium. That last is named after the Latin word tellus, the earth." "Do they dig it?" Ned wanted to know.
This curious relation was noticed by Dr. Wollaston, one of the most accurate of observers, and a little later it was confirmed by Johan Jakob Berzelius, the great Swedish chemist, who was to be a dominating influence in the chemical world for a generation to come.
The word isomerism was coined by Berzelius to express this anomalous condition of things, which seemed to negative the most fundamental truths of chemistry. Naming the condition by no means explained it, but the fact was made clear that something besides the mere number and kind of atoms is important in the architecture of a molecule.
Together they read the great works that appeared above the horizon of literature and science since the Peace the poems of Schiller, Goethe, and Byron, the prose writings of Scott, Jean-Paul, Berzelius, Davy, Cuvier, Lamartine, and many more.
Therefore a veritable sensation was created in the chemical world when, in the year 1828, it was announced that the young German chemist, Friedrich Wohler, formerly pupil of Berzelius, and already known as a coming master, had actually synthesized the well-known organic product urea in his laboratory at Sacrow.
