Página 68 - is a definite combination of heterogeneous changes, both simultaneous and successive, in correspondence with external coexistences and sequences.
Página 302 - Carbon, hydrogen, oxygen, and nitrogen are all lifeless bodies. Of these, carbon and oxygen unite in certain proportions and under certain conditions, to give rise to carbonic acid ; hydrogen and oxygen produce water ; nitrogen and hydrogen give rise to ammonia. These new compounds, like the elementary bodies of which they are composed, are lifeJess.
Página 2 - We have seen that a very considerable quantity of heat may be excited by the friction of two metallic surfaces, and given off in a constant stream or flux in all directions without interruption or intermission, and without any signs of diminution or exhaustion. In reasoning on this subject we must not forget that most remarkable circumstance that the source of the heat generated by friction in these experiments appeared evidently to be inexhaustible.
Página 85 - The colloidal is, in fact, a dynamical state of matter, the crystalloidal being the statical condition. The colloid possesses Energia. It may be looked upon as the probable primary source of the force appearing in the phenomena of vitality. To the gradual manner in which colloidal changes take place (for they always demand time as an element) may the characteristic protraction of chemico-organic changes also be referred.
Página 117 - ... chalk. Examined chemically, it proves to be composed almost wholly of carbonate of lime; and if you make a section of it, in the same way as that of the piece of chalk was made, and view it with the microscope, it presents innumerable Globigerince embedded in a granular matrix. Thus this deep-sea mud is substantially chalk.
Página 87 - absolute commencement of organic life on the globe," which the reviewer says I {' cannot evade the admission of," I distinctly deny. The affirmation of universal evolution is in itself the negation of an "absolute commencement " of anything. Construed in terms of evolution, every kind of being is conceived as a product of modifications wrought by insensible gradations on a pre-existing kind of being...
Página 52 - An active Principle : — howe'er removed From sense and observation, it subsists In all things, in all natures; in the stars Of azure heaven, the unenduring clouds, In flower and tree, in every pebbly stone That paves the brooks, the stationary rocks, The moving waters, and the invisible air. Whate'er exists hath properties that spread Beyond itself, communicating good, A simple blessing, or with evil...
Página 2 - It is hardly necessary to add, that anything which any insulated body, or system of bodies, can continue to furnish without limitation, cannot possibly be a material substance; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner the Heat was excited and communicated in these experiments, except it be MOTION.
Página 426 - Nec species sua cuique manet, rerumque novatrix ex aliis alias reddit natura figuras: nec perit in toto quicquam, mihi credite, mundo, sed variat faciemque novat, nascique vocatur incipere esse aliud, quam quod fuit ante, morique, desinere illud idem. cum sint huc forsitan illa, haec translata illuc, summa tamen omnia constant.
Página 248 - Their mingled atoms in each other fix. Thus Nature's hand the genial bed prepares With friendly discord, and with fruitful wars. From hence the surface of the ground...
