    ftrongly: when in its fluid Rate, very little; and when in its elaflic ftate, they are, on the contrary, repulfive. The like may be obferved of oil, of quicklilver, and many other fubftances, But different de- grees of heat are required to produce thefe effects in different bodies, as will be more fully feen in the courfe of the work. 6, Bodies gravitate, or tend towards the centre of the earth ; and the force with, which they gravitate, is in proportion to the quantity of matter which they contain. Thus, a quart of water contains twice as much matter as a pint of the fame fluid, and therefore gravitates twice as much ; or weighs twice as heavy: gravity and weight being fynonymous terms. 7- Different bodies, or fubftances, have different fpecific gravities. Thus, a pint of fpirit of wine weighs lefs than a pint of water, and therefore there is lefs matter in a pint of fpirit, than in a pint of water. Hence fpirit of wine is faid to have lefs fpecific gravity than water. On
