"Talking of Herbert Spencer," he began, "do you really find no logical difficulty in regarding Nature as a process of involution, passing from definite coherent homogeneity to indefinite incoherent heterogeneity?" Amused as I was at the ingenious jumble he had made of Spencer's words, I kept as grave a face as I could.
Higher than these in heterogeneity are the hydrates; in which an oxide of hydrogen, united with an oxide of some other element, forms a substance whose atoms severally contain at least four ultimate atoms of three different kinds.
Thus it is manifest that the present chemical heterogeneity of the Earth's surface has arisen by degrees, as the decrease of heat has permitted; and that it has shown itself in three forms first, in the multiplication of chemical compounds; second, in the greater number of different elements contained in the more modern of these compounds; and third, in the higher and more varied multiples in which these more numerous elements combine.
Perhaps no example can be given which more vividly illustrates the multiplicity and heterogeneity of the products that in course of time may arise by successive differentiations from a common stock.
At bottom Mr Bergson is bringing forward the necessity, in the case before us, of substituting a new notion of continuous qualitative heterogeneity for the old notion of numerical and spatial continuity.
It will be seen that as in each event of to-day, so from the beginning, the decomposition of every expended force into several forces has been perpetually producing a higher complication; that the increase of heterogeneity so brought about is still going on, and must continue to go on; and that thus Progress is not an accident, not a thing within human control, but a beneficent necessity.
The remaining space is taken up by paragraphs under a third of a column in length, with cross-headings as follows: 'Casualties and Offences; 'Police Intelligence; 'The Death of Mr. An analysis of the advertisements of the Argus is almost equally interesting as showing the heterogeneity of the wants of the community.
Thus, between our existing Earth, the phenomena of whose crust neither geographers, geologists, mineralogists, nor meteorologists have yet enumerated, and the molten globe out of which it was evolved, the contrast in heterogeneity is extreme.
Once more, the subsequent appearance of the vascular layer between these mucous and serous layers, as they have been named, admits of a like interpretation. And in this and the various complications which now begin to show themselves, we may see coming into play that general law of the multiplication of effects flowing from one cause, to which the increase of heterogeneity was elsewhere ascribed.
Considerations on the aspect of a country are independent of those which indicate the nature of the soil, the heterogeneity of matter, the superposition of rocks and the direction and inclination of strata. In taking a general view of the geological constitution of a chain of mountains, we may distinguish five elements of direction too often confounded in works of geognosy and physical geography.
