In the first experiments both investigators used organic substances as the reagent to cause the deposit of gold on its base, and in each case these substances whether woodchips, leather, or even dead flies, were found to be so absolutely impregnated with gold as to leave a golden skeleton when afterwards burned. Timber found in the Ballarat deep leads has been proved to be similarly impregnated.
I merely remark in passing that I gave orders to set aside a still greater fund toward finding a reagent against the Grass, and to put those who had lately assisted Miss Francis in charge. I did this, not because I swallowed her strained analogy about a sufferer with his legs cut off, but for purely practical reasons.
The reagents available for the reduction of iron are stannous chloride, sulphurous acid, sulphureted hydrogen, and zinc; of these stannous chloride acts most readily, the completion of the reaction is most easily noted, and the excess of the reagent is most readily removed.
On the contrary, the gas issuing from the platinum rapidly turned Nessler reagent brown, and in a few minutes turned faintly acid litmus solution blue; the odor of NH3 was also perceptible. In one experiment 0.0144 gramme of ammonia was formed in two hours and a half.
Thus they lay the foundations of life. This carbonaceous material with properties of movement and subdivision due to mechanical and physical forces is the immediate ancestor of the first imaginary living being, the protobion. To get this protobion the chemists summon a reagent known as a catalyser. The catalyser works its magic on the jelly mass.
There are various other tests such as gallo-tannic acid or infusion of nutgalls prepared a short time before application and may be used with advantage to restore writings that have been removed by washing. Place the document or paper on a sheet of white paper and moisten the whole of its surface with a paint brush dipped in the reagent, taking care not to rub it or strongly press it.
The thyroid, maybe, was first excited, and then in turn the adrenals, with a boomerang reinforcing effect upon the thyroid, and at the same time a stimulating effect upon the pituitary. Each gland is thus influenced and influencing, agent and reagent in the complex adjustments of the organism. The body-mind is a perfect corporation.
"Eradicating ink is simply a bleaching process," she remarked, "which leaves the iron of the ink as a white oxide instead of a black oxide. The proper reagent will restore the original color partially and at least for a time. Ah yes it is as I thought. There have been erasures in these checks. Other names have been written in on some of them in place of those that were originally there.
We want an explanation of the identical behaviour of the first with either of the two latter; and this should be borne in mind that the reaction is not a mere matter of "clearing" of a tissue as the histologist would clear his section by oil-of-cloves or other reagent, but of the construction of a different type of cell epithelial, not connective tissue.
Because a nature full and volatile in its free state, was alternately the agent and reagent of attraction. Because the controlled contemplation of the fluctuation of attraction produced, if desired, a fluctuation of pleasure. Abnegation? Equanimity?
