Mechanics, Electricity, Magnetism, Matter Theory, Gravity, Zoology,
Outlines theories of mechanics, the nature and properties of matter, and
gravity. Observes: 'Gold-beaters afford us the means of demonstrating the
minute diversibility [sic] of matter; they can spread a grain of gold into a
leaf containing fifty square inches; which leaf may be readily divided into
500,000 parts, each of which is visible to the naked eye. The natural divisions
of matter are, however, far more suprizingly [sic] minute: there are more
animals in the melt of a single cod-fish than men on the whole earth' (432). A
footnote explains: 'It is said that a single grain of sand is larger than four
million of these animals; yet each of them possesses a heart, stomach, bowels,
muscles, tendons, nerves, glands, veins, &c. It has been calculated that a
particle of blood of one of these animalcula, is as much smaller than a globe
one-tenth of an inch in diameter, as that globe is smaller than the whole
earth' (432). Also states: 'The attraction of matter has been exemplified in
five different ways, which philosophers have called the attraction of cohesion,
of gravitation, of combination, of electricity, and the magnetic attraction'
(432). Provides an account of gravitation and cohesion, including a footnote on
'capillary attraction' in plants and animals.
