Our anxiety during the King of France's escape, and our joy on his capture, cannot be described. I hope the new constitution is now effectually established, and that all attempts to overturn it will be in vain. The high-party here are mortified in the extreme. They would have had France involved in a most ruinous civil war, for the imaginary rights of one man. A majority, I fear, of Englishmen are in these sentiments, so that we are far indeed behind the French. In spite of all we can write or do, an attachment to high maxims of government gains ground here, and the love of liberty is on the decline. Such is the influence of the court. Nothing but public difficulties will open our eyes.

All hereditary Government is in its nature tyranny. An heritable crown, or an heritable throne, or by what other fanciful name such things may be called, have no other significant explanation than that mankind are heritable property. To inherit a Government, is to inherit the people, as if they were flocks and herds.

We more easily give our assent to any proposition when the person who contends for it appears, by his manner of delivering himself, to have a perfect knowledge of the subject of it.

It is known to all persons who are conversant in experimental philosophy, that there are many little attentions and precautions necessary to be observed in the conducting of experiments, which cannot well be described in words, but which it is needless to describe, since practice will necessarily suggest them; though, like all other arts in which the hands and fingers are made use of, it is only much practice that can enable a person to go through complex experiments, of this or any kind, with ease and readiness.

I was led into in consequence of inhabiting a house adjoining to a public brewery, where I at first amused myself with making experiments on the fixed air [carbon dioxide] which I found ready made in the process of fermentation. When I removed from that house I was under the necessity of making the fixed air for myself; and one experiment leading to another, as I have distinctly and faithfully noted in my various publications on the subject, I by degrees contrived a convenient apparatus for the purpose, but of the cheapest kind.
