The wourali and other poisons mentioned by Humboldt have, since the publication of this work, been carefully analysed by the first chemists of Europe, and experiments made on their symptoms and supposed remedies. I had myself no direct and sufficiently convincing proof of the action of this specific; and the experiments of Delille and Majendie rather tend to disprove its efficacy.
It is true, nevertheless, that, according to the chemists, composition may be after all but a mixture, or rather an aggregation of atoms, no longer fortuitous, but systematic, the atoms forming different compounds by varying their arrangement. But still this is only an hypothesis, wholly gratuitous; an hypothesis which explains nothing, and has not even the merit of being logical.
Du Moncel on the induction spark, and during the course of which he, in 1853, discovered that phenomenon of the electric efflux which has since been the object of important researches on the part of several physicists and chemists, among whom must be cited Messrs. Thenard, Hautefeuille, and Chapuis. Twenty years ago, Mr.
What chemists, for convenience, call elementary substances, are merely substances which they have thus far failed to decompose; but, bearing in mind past experiences, they do not dare to say that they are absolutely undecomposable.
I had long since prepared my tincture; I purchased at once, from a firm of wholesale chemists, a large quantity of a particular salt which I knew, from my experiments, to be the last ingredient required; and late one accursed night, I compounded the elements, watched them boil and smoke together in the glass, and when the ebullition had subsided, with a strong glow of courage, drank off the potion.
M. Lecoq did not share in his friend's indignation; he was not sorry at the prospect of a bitter struggle in court, and he imagined a great scientific duel, like that between Orfila and Raspail, the provincial and Parisian chemists. "If Tremorel has the face to deny his part in Sauvresy's murder," said he, "we shall have a superb trial of it."
There are chemists toiling away in their laboratories to create the primitive protoplasm from matter which is dead, the organic from the inorganic. I have studied their experiments. I know all that they know. Why shouldn't one work on a larger scale, joining to the knowledge of the old adepts the scientific discovery of the moderns? I don't know what would be the result.
Metals also had great medicinal potency. Antimony, lead, iron, mercury, were well known, and of special importance was copper, the Venus of the early chemists. The medicinal virtue which inhered in Butler's stone and in other powerful fermental remedies, van Helmont designated as "drif," which he said means, in the vernacular, virgin sand or earth.
Chemists have directed their attention to the molecular structure the ultimate constitution of various compounds. Among the recent elements which have been discovered are argon, which enters into the composition of air, helium, and radium. BIOLOGY. No branch of natural science has been more zealously cultivated of late than biology.
Why are we made serious and solemn and sublime by mountain heights, grave and contemplative by an abundance of overhanging trees, reduced to inconstancy and monkey capers by the ripples on a sandy beach? Did the protoplasm but enough. The chemists are looking into the matter, and before long they will have all life in the table of the symbols.
