fryingpan that has been leadened, stirring with a wooden or iron ladle until they grow red, and their oil is poured out, which they yield the more largely if compressed with the ladle. This oil of eggs is described in similar terms by Moses Charras, in the Royal Pharmacopœia (p. 200), and is a popular remedy in Scotland to this day. Mesue describes the composition of an oil of frogs, which he recommends much for soothing the pains of arthritis, and the burning heat of ardent fevers, also the oil of vipers, of wolves, and many others, which will be more properly treated of by us in section xx of this Book. The oils are also well described by Aëtius (i) and Myrepsus (De Oleis.) Ἐλαιόμελι, Elæomeli, _Honeyed Oil_. In Syria, an oil thicker and sweeter than honey, flows from a certain trunk; when drunk to the amount of two cyathi with a hemina of water, it produces a discharge of crude and bilious matters from the bowels. Those who have taken it become torpid; yet one need not be alarmed, but only rouse them. * * * * * COMMENTARY. Pliny describes it as a natural exudation from trees on the maritime coasts of Syria. He adds, it is fat, thicker than honey, thinner than resin, of a sweet taste, and is used in medicine: “Manat ex arboribus pingue, crassius melle, resina tenuius, sapore dulci, et hoc medicis.” (H. N. xxv, 7.) He states in another place that it is a nauseous purgative. (xxiii, 56.) Dioscorides gives the same account of it as our author, and describes an oil to be prepared from it. Avicenna and Rhases recommend it as an application to ulcerated scabies. It appears singular that this natural substance should have been entirely lost sight of in modern times, inasmuch that unless we adopt the conjecture of Alston, that it was some species of manna, we must admit ourselves entirely ignorant of it. Ἐλατήριον, Elaterium; the juice of the fruit of the wild cucumber is so called, being in the second order of calefacients. It promotes the menstrual discharge, and destroys the fœtus when applied in a pessary, by its extreme bitterness. When rubbed in with milk it evacuates by the nose. When administered in an injection, it occasions a discharge downwards of phlegm, and sometimes of blood. * * * * *
