If we thought Howie was upset over the Youngblood matter, it was arsenic versus ice cream compared to how enraged he was over a challenge to his ability.
Cobalt is usually found associated with nickel, and frequently with arsenic, the chief ores being speiss-cobalt, (Co,Ni,Fe)As 2, cobaltite, wad, cobalt bloom, linnaeite, Co 3 S 4, and skutterudite, CoAs 3.
Hausmann in 1813, alludes to the arsenic and iron present (cfipµ.aKov, poison, and aLo pos, iron).
Arsenic, in its well-known and beautiful forms, orpiment and realgar, is found in New South Wales and Victoria.
Simultaneously Hermann, a German chemical manufacturer, discovered the new metal in a specimen of zinc oxide which had been thought to contain arsenic, since it gave a yellow precipitate, in acid solution, on the addition of sulphuretted hydrogen.
This precipitate is insoluble in cold dilute acids, in ammonium sulphide, and in solutions of the caustic alkalis," a behaviour which distinguishes it from the yellow sulphides of arsenic and tin.
In response to an agitation originated by certain manufacturers (one of whom was a member of parliament), who were prosecuted for omitting to label arsenical and nicotine preparations as poisons, as required by the Pharmacy Act of 1868, a new act was passed in 1908, by which persons, without any training in toxicology, and being neither pharmaceutical chemists, nor chemists and druggists, may be granted licences by local authorities to sell poisonous substances used exclusively in agriculture or horticulture, for the destruction of insects, fungi or bacteria, or as sheep dips or weedkillers, but which are poisonous by reason of containing the scheduled poisons, arsenic or nicotine, &c. One condition concerning the granting of such licences has been, it is said, deliberately ignored in many towns, viz.
His first original paper (1799) was on the compounds of arsenic and antimony with oxygen and sulphur, and of his other separate investigations one of the most important was that on the compound ethers, begun in 1807.
The molybdates are also capable of combining with other oxides (such as phosphorus and arsenic pentoxides) yielding very complex salts.
Such pyrites sulphur is usually contaminated with arsenic, and conse- quently is of less value than Sicilian sulphur, which is characteristically free from this impurity.
There is some evidence that arsenic has a prophylactic effect.
One group was treated with arsenic, and of these 36 escaped altogether, while three had mild attacks; the remaining 39.
This was in 1889; but in spite of the encouraging results the use of arsenic does not appear to have made any further progress.
The prima materia thus obtained had to be treated with sulphur (or with sulphur and arsenic) to confer upon it the desired qualities that were missing.
Thus in the Speculum Naturale of Vincent of Beauvais (c. 1250) it is said that there are four spirits - mercury, sulphur, arsenic and sal ammoniac - and six bodies - gold, silver, copper, tin, lead and iron.
He found, however, that chromic acid, which he had represented as Cr06, neutralized a base containing 3 the 3 The following symbols were also used by Bergman: W, V, " + ", which represented zinc, manganese, cobalt, bismuth, nickel, arsenic, platinum, water, alcohol, phlogiston.
Prolonged ingestion of arsenic may cause pigmentary changes in the skin.
Natasha was very ill, having, as Marya Dmitrievna told him in secret, poisoned herself the night after she had been told that Anatole was married, with some arsenic she had stealthily procured.
