They are largely imported into Liverpool . They are sent to the western coast of Africa for barter with the natives. A species of this family called the C. princeps, " the brindled cowry of the Persian gulf," is very highly prized by conchologists for its rarity and beauty. Only two specimens are known ; one is in the British museum, and the other was sold some years since in London, at the sale of the col- lection of the earl of Mountnorris, for 40. A specimen of the C. umbilicata was sold in 1850 for 30. The cowries, from the great variety and beauty of the markings upon their smoothly polished surface, have long been in demand among civilized and uncivilized na- tions for ornaments to their dress and habita- tions. The tiger cowry (C. tigris) is the one so generally seen upon the mantels of houses in various parts of this country.

Of this sap Alexander von Humboldt, who first brought the tree to the notice of for- eigners, writes: "We were assured that the negroes on the farm, who are in the habit of drinking large quantities of this vegetable milk, consider it as highly nutritive; an assertion which startled us the more, as almost all lac- tescent vegetable fluids are acrid, bitter, and more or less poisonous. Experience, however, proved to us, during our residence at Barbula, that the virtues of the cow tree, or palo de vaca, have not been exaggerated." COX, David, an English landscape painter, born in Birmingham in 1793, died in 1859. His paintings, chiefly on Welsh subjects, are in water colors, small, and apparently careless, but full of the impression and effect of nature. He succeeded best in sketching rain and wind, bursts of sunshine on dark moors, and the dank herbage of marshes. He published in 1814 a "Treatise on Landscape Painting in Water Colors," which is still considered the best series of lessons on water-color painting. His son DAVID is also a painter of ability.
