One case was that of a girl who ate spiders from her childhood, and was so fortified against poisons as not to be afraid to take any of them. A man is alluded to by Galen who would drink a cup of wine in which a live viper had been drowned. We have also the account of a girl whose system had been so saturated with aconite that an Indian king had sent her as a present to Alexander the Great in the hope that he would kiss her, and thus imbibe the poison with which her lips would be charged; but, fortunately, Aristotle saw her first, and recognised by her flaming eyes that she was filled with some sort of poison, and thus the Indian’s purpose was frustrated. After another interval and some more music, the lecturer came to the third part of his subject, in which he expounded the special virtues of the drugs before him. These were grouped, and it was shown that some were good for the brain, others for the chest, for the stomach, for the kidneys, the heart, and other organs. Others, like the viper’s flesh, were directly sympathetic with poisons, and would go straight for them if they were inside the body, or would lie in wait for them, as it were, if they were only expected. When the subject was exhausted, it was announced that in consequence of the lateness of the hour the weighing of the ingredients would be postponed till the next day. That ceremony was duly performed on the 24th of September, and the drugs were passed on to a “pulveriser.” It was not until the 16th of November that the final mixing was undertaken. KERMES. Kermes as a pharmaceutical term reaches us through the Arabic, qirmis, red. But it was not a native Arabic word. It was adopted into that language from the Persian, and was of Sanskrit origin. The word Krimija in Sanskrit meant produced by a worm, and was itself from krimi, a worm; worm is the direct English descendant of krimi. Kermes is responsible in modern English for carmine and crimson, but it need hardly be said that it has no connection with the Flemish kermess though it looks so like it. Kermess is kerkmess, or, in English, church-mass. The kermes of the Arabs was the kokkos of the Greeks, coccus of the Romans. It was found on a species of oak, now called the Quercus ilex, a low, shrubby, evergreen bush with prickly leaves like the holly. The tree, however, bears acorns. The ancients generally regarded these insects as the fruit of the trees, though they were aware that worms came from them. But these they thought were produced from the corruption of the fruit. The principal use they made of them was in dyeing, and for this purpose they were employed until the superior coccus cacti from Mexico superseded the coccus ilicis. In the middle ages kermes was retained as the medicinal name, but for dyeing the insects were called vermiculi, and the cloth dyed by them was known as vermiculata. From this came the French word vermeil, and from that vermilion was derived.
