And again, in a communication from Montbard (_La Patrie_, 19th September, 1858) it is stated that a youth sixteen years of age was drinking from a bottle, when a wasp, which he had not seen, got into his throat and wounded him. He died suffocated by the swelling, before any assistance could be procured. According to Messrs. Kirby and Spence (_Introduction to Entomology_, Seventh Edition, p. 76, London, 1856), serious effects are sometimes produced on peculiar constitutions by eating freely of honey or from partaking of mead—a drink made by fermenting honey and water. These authors state that they knew a lady upon whom such things acted like poison, and they had heard of instances in which death was the consequence. Sometimes, when the bees have extracted their sweets from poisonous plants, these injurious results have not been confined to individuals of a particular habit. Thus, according to Dr. Barton (_American Philosophical Transactions_, vol. 5), there were numerous deaths in the autumn and winter of 1790 from eating honey collected in the neighborhood of Philadelphia, which, on inquiry, was found to be due to this substance having been extracted from the beautiful but poisonous flowers of the Kalmia latifolia. * * * * * The following Table from Dr. Garrod’s “Materia Medica” shows the proportions in which some of the more important drugs of the “Pharmacopœia” are contained in the Officinal Preparations.
