Стр. 102 - All these things being considered, it seems probable to me that God, in the beginning, formed matter in solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties, and in such proportions to space, as most conduced to the end for which He formed them...
Стр. 70 - O apparently incredible proposition, that ' when two elastic fluids, denoted by A and B, are mixed together, there is no mutual repulsion amongst their particles — that is, the particles of A do not repel those of B, as they do one another ; consequently, the pressure or whole weight upon any one particle arises solely from those of its own kind.
Стр. 55 - I was always of opinion, though I might not often mention it, that several colours were injudiciously named. The term pink, in reference to the flower of that name, seemed proper enough; but when the term red was substituted for pink, I thought it highly improper; it should have been blue, in my apprehension, as pink and blue appear to me very nearly allied; whilst pink and red have scarcely any relation. In the course of my application to the sciences, that of optics necessarily claimed attention;...
Стр. 123 - Chemical Synthesis. When any body exists in the elastic state, its ultimate particles are separated from each other to a much greater distance than in any other state; each particle occupies the centre of a comparatively large sphere, and supports its dignity by keeping all the rest, which by their gravity, or otherwise are disposed to encroach up it, at a respectful distance.
Стр. 57 - I found that persons in general distinguish six kinds of colour in the solar image; namely, red, orange, yellow, green, blue, and purple.
Стр. 60 - There is not much difference in colour between a stick of red sealing-wax and grass, by day. 6. Dark green woollen cloth seems a muddy red, much darker than grass, and of a very different colour. 7. The colour of a florid complexion is dusky blue. 8. Coats, gowns, &c. appear to us frequently to be badly matched with linings, when others say they are not. On the other hand, we should match crimsons with claret or mud ; pinks with light blues ; browns with reds ; and drabs with greens. 9- In all points...
Стр. 70 - Thus, the force of aqueous vapour of 212° is equal to 30 inches of mercury; at 30° below, or 182°, it is of half that force ; and at 40° above, or 252°, it is of double the force ; so likewise the vapour from sulphuric ether which boils at 102°, then supporting 30 inches of mercury, at 30°...
Стр. 125 - When three combinations are obtained, we may expect one to be a binary and the other two ternary. 4th. When four combinations are observed, we should expect one binary, two ternary, and one quaternary, &c.
Стр. 198 - ... intuitive skill in tracing the relations of material phenomena, would have been of comparatively little value to himself and to society, had there not been superadded to them a beautiful moral simplicity and singleness of heart, which made him go on steadily in the way he saw before him, without turning to the right hand or to the left, and taught him to do homage to no authority before that of truth.
Стр. 213 - ... denoting that but little had fallen during the day. His servant observed that his hand trembled more than he had ever before seen it, and that he could scarcely hold the pen. Indeed, the book exhibits, in its tremulous characters and blotted figures, striking proofs ot the rapid decay of the physical powers.
