Yes, to several persons; but trusted nobody with it out of my sight. Why do you believe it to be white arsenic? For the following reasons: This powder has a milky whiteness; so has white arsenic. This is gritty and almost insipid; so is white arsenic.
During her trial mention was made of packets found in a chest she had used while at Locsine, the place where seven deaths had occurred. But it was never clearly established that these packets had contained arsenic. It was never clearly established, though it could be inferred, that Helene ever had arsenic at all.
On the whole, I rather favour the use of mercury in the box at any time, unless the ore is very refractory that is, contains too great a proportion of base metals, particularly sulphides of iron, arsenic, etc., when the result will not be satisfactory, but may entail great loss by the escape of floured mercury carrying with it particles of gold.
It was instantaneously agreed they should mutually swallow such a quantity of arsenic, as would speedily effect their dreadful purpose. She composed the fatal draught before his face and even set him the desperate example of drinking first. By this device, which had all the appearance of the greatest affection and candor, the dregs only were reserved for him, and soon put a period to his life.
Sometimes these are merely harmless; as flour, starch, annatto, lard, etc.; sometimes they are vigorous, destructive poisons as red lead, arsenic, strychnine, oil of vitriol, potash, etc. It is not agreeable to find ourselves so thickly beset by humbugs; to find that we are not merely called on to see them, to hear them, to believe them, to invest capital in them, but to eat and drink them.
It is a theory in the same sense in which it is a theory that day and night follow each other, that lead is heavier than water, that bread nourishes, that arsenic poisons, that alcohol intoxicates.
In solution, arsenic may be detected by the liquid tests. Sulphuretted hydrogen water gives a yellow precipitate. Marsh's Process. Put pure distilled water into a Marsh's apparatus with metallic zinc and sulphuric acid. Hydrogen is set free, and should be tested by lighting the issuing gas and depressing over it a piece of white porcelain.
The same action effects the elimination of the arsenic and antimony associated with gold and silver ores, as when heated to a certain constant temperature these metals readily oxidise.
That the corporal's vision was no fiction, was evident the lad was not to be hurt by mortal man; but although the widow's arsenic had failed, Mr Vanslyperken, in his superstition, accounted for it on the grounds that the woman was not the active agent on the occasion, having only prepared the herring, it not having been received from her hands by Smallbones.
In others the patient falls into a deep sleep, while in the fourth class the symptoms resemble closely those of English cholera. The vomited matters are often blue from indigo, or black from soot, or greenish from bile, mixed with the poison. Should the patient survive some days, no trace of arsenic may be found in the body, as the poison is rapidly eliminated by the kidneys.
