Heat is a motion of the small parts of bodies.

Sound is a motion of the air, and is propagated in waves.

The elasticity of bodies is caused by the springiness of their parts.

Ut tensio, sic vis (As the extension, so the force).

I have invented a new way of measuring the force of the wind.

I have designed a new kind of barometer, which will be more accurate than the old ones.

I have invented a new method of making clocks go more accurately, by the help of a pendulum.

I have made a new kind of thermometer, which will be more sensitive than the old ones.

I have invented a new way of making telescopes, which will be more powerful than the old ones.

I have designed a new kind of microscope, which will be more powerful than the old ones.

I have invented a new way of making watches go more accurately, by the help of a balance spring.

I have been much engaged in the study of fossils, and have discovered many new species.

The earth has undergone many changes, and has been subject to many floods and earthquakes.

I have been much troubled with the gout, and have taken many remedies, but to little purpose.

My sight is almost gone, and I can hardly see to write.

I am now very old and infirm, and expect every day to die.

I have lived a laborious life, and have made many discoveries, but have met with little reward.

The truth is, the science of nature has been already too long made a work of the brain and the fancy. It is now high time that it should return to the plainness and soundness of observations on material and obvious things.

By the help of microscopes, there is nothing so small, but we may hope to find some excellent use of it.

The business of the Royal Society is to improve the knowledge of natural things, and all useful Arts, Manufactures, Mechanic practices, Engines and Inventions by Experiment.
