Nuculae sapnariae non edules C. B. Sa-Qonaria sphaerulae arboris filicifoliae J. B. Bacca bermudenfes Marloe. Soap-berries: a sphe-rical fruit, about the size of a cherry; whole cortical part is yellow, gloffy, and so trans-parent, as to shew the spherical black nut, which rattles within, and which includes a white kernel. It is the produce of a small tree, growing in Jamaica and other parts of the Weft Indies, called by Sir Hans Sloane prunifera racemosa, folio alato, costa media membranulis utrinque extantibus donata, fructu.saponario; by Linnaeus, Sapindus Saponaria.
It is said that this fruit, at least its cortical part, has a very bitter taste, and no smell: that it raises a soapy froth with water, and has similar effects with soap in washing: that it is a medicine of Angular and specific virtue in chlo-rofes: and that a tincture or extract are preferable to the berry in substance, from whence it may be presumed that its soapy matter, like that of the saponaria, is dissoluble in spirit. Its medicinal virtue was first published by Marloe in a letter to Mr. Boyle; but the fruit having been concealed under the fictitious name of Bermudas berries, its use died with the author. That Marloe's Bermudas berries were the same with the soap-berries of America, had been suspected by some, and was confirmed by Dale in examining the Bermudas berries which Marloe had left under that title behind him. They are still, however, unknown in practice, and in the shops.
