Lately, in a coal-pit situated upon the outwood, near Wakefield, and belonging to Wm. Fenton, Esq. out of the lower bed or seam, at a distance of 150 yards from the surface of the earth, a block of coal was dug up, which, when broken, contained a lizard, of the species vulgarly called askers; the animal was alive, but upon being exposed to the air, it soon died. The cavity in which it was found, being the exact mould of its own form, no chasm, hole, or external crack appeared on the surface of the block.
