The work of Ælius Promotus on Venomous Animals and Poisonous substances, which exists in MS. in the Bibliotheca Vaticana, has never been published as far as we know. It is quoted by Hieronymus Mercurialis (Var. lect), and is noticed by Albertus Fabricius (Bibl. Græc. xiii, 780.) Fabricius supposes it to be the production of Æschrion Empiricus. It is proper to state that whenever we quote the work, it is from the extracts given in Schneider’s Annotations on Nicander. It is to be borne in mind that the work on Poisons, usually published as the production of Dioscorides, is not held to be genuine by his latest editor, Sprengel; still, however, it is acknowledged by all to be a work of considerable antiquity and of great authority on the subject of ancient Toxicology. The work ‘Euporistôn,’ which is also published with the works of Dioscorides, is generally admitted not to be genuine. It contains, however, some valuable matter on Toxicology and other medical subjects. These directions of our author for driving away reptiles are mostly taken from Nicander, who recommends fumigations with hartshorn, gagate-stones, sulphur, bitumen, galbanum, juniper, and other such articles. (Ther. 35.) See also Dioscorides (M. M.); Orpheus (de Lapidibus); Geopon. (xiii, 8); and Nonnus (Epit. 261); also Aristot. (H. N. iv, 8); and Pliny (H. N. x, 90). Virgil makes mention of this practice: “Disce et odoratam stabulis accendere cedrum, Galbaneoque agitare graves nidore chelydros.” _Georg._ iii, 314. See a long list of substances used in fumigations for driving away serpents in Lucan. (Pharsal. ix, 916.) It is different from that of Nicander and our author. For example: it contains tamarix, costus, thapsos, &c. Arsenic occurs among the articles mentioned by Rhases. (Cont. xxxv.) It is also mentioned in the Geoponics (l. c.) Nicander affirms, and it has been generally believed, that human saliva proves destructive to serpents. Galen says that it will kill the scorpion. Aristotle states, that it is destructive to most venomous reptiles. (H. A. viii, 28.) Redi maintains that this is an ancient error; but Andreas Laurentius declares that he knew from experience that the human saliva is destructive to serpents.
