It fhould be obierved here, that tint fpccimens of this kind in the King's cabinet, arc 7 inches long, by 5 wide, as it is necelfary they fiiould pollels this magnitude, in order to trace accurately the charaders of a wood or marble, In the wood, moreover, fhould'be a tranfverfc! fecflion; in a Hump 10 inches long, they may eafily take a round or folid piece cut tranfverlely, and a fmall board or plank, 7 inches long, fawed longitudinally, by an incifion which paflcs through the pith. The voyagers, where they land, may happen to meet v/ith tourmalines and other cryflals, which become eledlric by fimple heat. As mod part of thefe cryflals are in clufters adhering to the gangue by one of their extremities, and in different diredions, the academy recommends to the travellers to make experiments, to afcer- tain whether the fpecies of pofitive or negative eledlricity, confhantly manifefted by thefe cryflals at one of their ends, have any relation to the po- lition of thefe cryflals, whether on their gangue, or relatively to one another.
