Diadelphia

(From Diadelphia 2749 twice, and a brother). The name of the seventeenth class, in Lin-naeus's artificial system, comprehending those plants which bear hermaphrodite flowers, with two sets of united stamina. This is a natural class with papilionaceous, or pea flowers, and leguminous fruits. The orders are founded on the number of stamina; and ten being the predominating number in this class, the order decandria is much the largest. The regular disposition of the stamina in this order is, nine united in one brotherhood, the lower broad part of the filament sheathing the germ, and the tenth single; but in almost twenty genera, the ten staminas are connected into one body at the bottom.

Diadexis

And Diadoche, (from Diadexis 2751 and to transfer). See Metastasis.

Diadosis

(From Diadosis 2753 to distribute or dissipate). In medicinal authors it signifies to remit, though sometimes it means the distribution of the aliment over all the body.

Dlaeresis

(From Dlaeresis 2754 to divide or separate).

It is taken generally, from Galen, to be a solution of continuity, of which he forms four species, wounding, contusion, erosion, rupture; it is now used in this sense from whatever cause the solution arises.

Diaglaucium

The name of a collyrium recommended by Scribonius Largus. It is thus named from Glaucium, which, according to Dioscorides, is the juice of the papaver spinosum.

Diagrydium

Also Dacrydium; which see. A preparation of scammony; but indeed the general name of the resin itself: quasi Diagrydium 2758 lachrymula, because the juice issuing from the wounded root was called lachryma scammonii. Its great activity was corrected by the ancient physicians by exposing it to the fumes of burning sulphur; in reality combining it with the vitriolic acid, and it is then called diagrudium sul-jihuratum. It is sometimes incorporated with the spiritus vitrioli rosati, sufficient to make a liquid paste, which is afterwards dried in the sun or by a gentle fire; called diagrydium rosatum; occasionally it has been baked in a quince: but all these modes are of not the slightest consequence as correctors; nor, indeed, does the medicine require correction. See Scammonium.

Diahermodactylus

(From Diahermodactylus 2759 and

Diahermodactylus 2761 ). A purging medicine, of which hermodactyls form the basis.
