Water is 400 (perhaps 2000) times heavier than aire & gold 19 times heavier than water. Quæst: What proportion the weights of two bodys as gold & silver have in divers mediums as in vacuo aere aqua &c: which known the weight of the aire or water in vacuo or the quantity of gold to the silver is given &c: As if in aire the Gold (a) is equiponderant to the silver (z) the weight {a} it being called b. And in water the gold (a) is equiponderant to the silver (2z). let (c) bee the weight of so much water in the aire as is equall to the Gold a then is cza the weight of so much water as is equall to the silver az. Then the gold & silver weighed in water their weights are diminished by the weight of the water whose place they conteine. Therefor b - c is the weight of the gold a in the water & b - cza is the weight of the silver (z) in it, & since b is equiponderant to 2z in it Therefore b - c = 2b -2 cza or ab+ac2c = z. that is 2c : b + c :: a : z. Or if (c) the weight of water in the aire is sought then abzz-a = c. Thus might the absolute weights of bodys i: e: their weights in vacuo bee found. as of air or the Bodys or fire in a hot furnace without flame {&c} Continue reading…
