In these cases, as a general thing, the discolorations occur only after several days a faultless mirror having been made at first, and the browning subsequently developing slowly. The writer was a student in the laboratory of Baron Liebig during the time that distinguished chemist was carrying out the series of experiments which resulted in devising a method of making silver mirrors commercially.
So, at least, says Liebig, who states that he found a small piece of matchwood, just extinguished, burst out again into a flame on being immersed in the bubbles given out by these living atomies. But all the sea-weeds, in common with other vegetables, perform this function continually, and thus maintain the water in which they grow in a state fit to support animal life.
We refer, in the case of the individual organism, to the blood-discs; and in the case of the social organism, to money. This analogy has been observed by Liebig, who in his Familiar Letters on Chemistry says: "Silver and gold have to perform in the organism of the state, the same function as the blood-corpuscles in the human organism.
He at once made him acquainted with Gay Lussac, the famous Parisian chemist, and Liebig was thus placed on the road to the lofty position which he was afterwards to occupy in all the departments of science. The Munich zoologist von Siebold we first knew intimately years after.
Here Liebig failed to perceive that the ferment, in its capacity of a living organism, had anything to do with the fermentation. This theory dates back as far as 1843. In 1846 Messrs. Boutron and Fremy, in a Memoir on lactic fermentation, published in the Annales de Chimie et de Physique, strained the conclusions deducible from it to a most unjustifiable extent.
"There is a difference," says Mr. Urquhart, "between radiating and transmitted caloric.... I cannot pretend to treat of this great secret of nature; to work out this problem a Liebig is required. This I can say, that such heat is more endurable than common heat. There is a liveliness about it which transmitted heat lacks. You are conscious of an electrical action.
The origin of the stalactite is thus explained by the eminent chemist Liebig. Mould or humus, being acted on by moisture and air, evolves carbonic acid, which is dissolved by rain.

Of what particular service recent investigations in science have been to the practical farmer, and what positive and available aid, beyond what could be derived from a careful study of the Roman masters, they put into the hands of an intelligent worker, who is tilling ground simply for pecuniary advantage, I shall hope to inquire and discourse upon, some other day: when that day comes, we will fling out the banner of the nineteenth century, and give a gun to Liebig, and Johnson, and the rest.
Both Liebig and Johannes Müller remained vitalists, notwithstanding the discovery of the synthesis of urea and the increasing number of organic compounds which were built up artificially by purely chemical methods.
