Side 201 - England will, beyond question, at no distant day become herself the greatest colourproducing country in the world ; nay, by the strangest of revolutions, she may ere long send her coal-derived blues to indigo-growing India, her tar-distilled crimson to cochineal-producing Mexico, and her fossil substitutes for quercitron and safflower to China, Japan, and the other countries whence these articles are now derived.
Side 61 - Without offering any hypothesis regarding the cause of this symmetrical grouping of atoms, it is sufficiently evident, from the examples just given, that such a tendency or law prevails, and that, no matter what the character of the uniting atoms may be, the combining power of the attracting element, if I may be allowed the term, is always satisfied by the same number of these atoms.
Side 42 - Avogadro's law states that equal volumes of all gases at the same temperature and pressure contain the same number of molecules...
Side 98 - This body is found to have two highly distinguishing characteristics : — 1. It combines with equal numbers of hydrogen, chlorine, oxygen, sulphur, etc. 2. It enters into chemical union with itself. These two properties, in my opinion, explain all that is characteristic of organic chemistry. This will be rendered apparent as I advance. This second property is, so far as I am aware, here signalized for the first time.
Side 67 - Carbon is the only element which is essential to organic compounds; every one of the other elements may be absent from particular compounds, but no compound which in all its relations deserves the name "organic
Side 208 - Pingunt et v'estes in Aegypto inter pauca mirabili genere , candida vela postquam attrivere illinentes non coloribus , sed colorem sorbentibus medicamentis. Hoc cum fecere, non apparet in velis , sed in cortinam pigmenti ferventis mersa post momentum extrahuntur picta. Mirumque, cum sit unus in cortina colos , ex illo alius atque ulius fit in veste accipientis medicamenti qualitate mutatus.
Side 208 - ... in velis, sed in cortinam pigmenti ferventis mersa post momentum extrahuntur picta. mirumque, cum sit unus in cortina colos, ex illo alius atque alius fit in veste accipientis medicament! qualitate mutatus, nee postea ablui potest. ita cortina, non dubie confusura colores, si pictos acciperet, digerit ex uno pingitque, dum coquit, et adustae eae vestes firmiores usibus fiunt quam si non urerentur.

Side 61 - ... even a superficial observer is struck with the general symmetry of their construction; the compounds of nitrogen, phosphorus, antimony and arsenic especially exhibit the tendency of these elements to form compounds containing...
