placed at the head of crystals or precious stones by the mineralogists,
till Bergman ranged it of late in the combustible class of bodies,
because by the focus of Villette's burning mirror it was evaporated by a
heat not much greater than will melt silver, and gave out light. Mr.
Hoepfner however thinks the dispersion of the diamond by this great heat
should be called a phosphorescent evaporation of it, rather than a
combustion; and from its other analogies of crystallization, hardness,
transparency, and place of its nativity, wishes again to replace it
amongst the precious stones. Observ. sur la Physique, par Rozier, Tom.

Light on his back the sportive Damsel bounds,
And pleased he moves along the flowery grounds;
Bears with slow step his beauteous prize aloof,
Dips in the lucid flood his ivory hoof;
245 Then wets his velvet knees, and wading laves
