of this work. It is the tellini fly of the Hindoos. See Ainslie (Mat. Ind. ii, 417.) The ancients prepared the cantharides for medicinal use in the same manner as the Spanish fly is now prepared, namely, by killing them with the fumes of vinegar. Dioscorides says cantharides are septic, ulcerative, and calefacient, and hence are mixed up with the medicines that cure cancerous diseases, leprosy, and lichen agrius; they are also emmenagogue when applied in a pessary; and some, he adds, relate that cantharides are beneficial in dropsies, by acting as diuretics. Their wings and feet are further said to be antidotal, that is to say, we suppose, to counteract the operation of the body of the insect. (ii, 65, 66.) Galen treats of the cantharis and buprestis in very nearly the same terms as Dioscorides. Instead of using only the wings and feet, as mentioned by Dioscorides, he says that he used the whole insect. (De Simpl. xi.) In moderate doses he held it to be a safe diuretic. (ii, 463, ed. Basil.) Aëtius and Oribasius give nearly the same account of the cantharis as Galen. Cantharides are frequently mentioned in the Hippocratic treatises (De Nat. Mulier. 565, ed. Föes; De Intern. Affect. 552), and in the works of Celsus. (199, ed. Milligan.) Aretæus is the first author, as far as we know, who notices the external use of cantharides as a rubefacient. (De Curat. Morb. Chron. i, 4.) The Arabians, in treating of cantharides, borrow nearly all the information they give from Dioscorides and Galen. See Serapion (c. 441), Avicenna (ii, 2, 201), Rhases (Cont. l. ult. i, 162.) Rhases on his own authority, affirms, that administered in small doses cantharides cleanse the kidneys. We are rather surprised to find that the _Mylabris_ does not occur in the modern Greek Pharmacopœia.

Κάνναβις,

Cannabis, _Hemp_; the fruit is carminative and desiccative, so as to dry up even the semen. The juice of it when green is useful for pains of the ears and obstructions of them.

* * * * *

COMMENTARY. It appears evidently to be the _Cannabis sativa_, or Hemp. The species _sylvestris_ of Dioscorides, is the _Althæa Cannabina_. See Sprengel (ad Dioscorid. iii, 155), and Parkinson (Theatre of Plants, 307.) Dioscorides recommends the latter in the form of a cataplasm to soothe inflammations and discuss tumours. Our author copies from Galen, who, like him, only describes the _sativa_. The Arabians describe both species with more accuracy than the Greeks. See Avicenna (ii, 2, 170, 656), Serapion (207.) Avicenna calls them carminative and desiccative; and hence he holds that they dry up the semen. He says a middling dose proves laxative of the bowels.

Κάνωπον,

Canopum, _the Flower of the Elder-tree_, which has been already treated of.

Κάπνιον,

Fumaria, _Fumitory_ (called also Capnos), and is so named because the juice of it provokes a great discharge of tears; and it sharpens the vision. It is also acrid and bitter; hence it occasions a discharge of much bilious urine, and cures obstructions and atony of the liver. It also strengthens the stomach and softens the belly.

* * * * *

COMMENTARY. All the commentators seem agreed that it is the _Fumaria officinalis_, except Sibthorp, who prefers the _F. parviflora_, Lam. Our author’s account of it is mostly taken from Dioscorides and Galen. The others give nearly the same description of its medicinal virtues. See particularly Serapion (c. 71), and Avicenna (ii, 2, 275.) They represent it as being a stomachic and hepatic medicine, gently purgative and diuretic. Fumitory is described as a medicinal herb by all our old herbalists, and held a place in the Dispensatory down to a late date. See Quincy (125.) The _F. officinalis_ is still retained in the modern Greek Pharmacopœia.

Κάππαρις,

Caparis, _Caper-tree_; its root deterges, purges, incides, and discusses by its bitterness and acrimony. It also contracts, astringes, and condenses by its sourness. It therefore cures indurated spleens when drunk and when applied externally. It is also emmenagogue, and occasions a discharge of phlegm. It cures ill-conditioned ulcers, and relieves pains of the teeth, dispels tumours and alphos, and kills vermin in the ear. The leaves and fruit of it are possessed of similar powers, but weaker.

* * * * *

COMMENTARY. It is the _Capparis spinosa_, namely, the plant which produces our officinal capers. Dioscorides and Serapion mention that pickled capers act as a gentle laxative, but say that they are bad for the stomach. The Arabians held that they are good whetters of the appetite. Casiri (Bibl. A. H. i, 337.) Galen gives a very elaborate article on the virtues of capers, which, he says, are the best medicine which we possess in scirrhous enlargement of the spleen. He says it clears away the humours by the belly and by urine, and also acts as an emmenagogue. Their taste, he says, is a combination of bitterness, acrimony, and sourness. He concludes by stating that capers produced in very warm climates, such as Arabia, are much more acrid than in his country. (De Simpl. vii.) The Arabians held that capers are aphrodisiacal and alexipharmic. See Rhases (Contin. l. ult. i, 164), Avicenna (ii, 2, 138), and Serapion (c. 291.)

Κάρδαμος,

Nasturtium, _Cress_; the seed of it is caustic like mustard. When applied externally, therefore, it proves rubefacient, incides also the thick humours when drunk with other things. And the dried herb is possessed of similar powers, but the juicy one is more moderate; it therefore is eaten raw.

* * * * *

COMMENTARY. It was indisputably a species of cress, probably the _Lepidium sativum_. We have treated of it as an article of food in
