In hermaphrodite organisms which cross only occasionally, and likewise in animals which unite for each birth, but which wander little and which can increase at a very rapid rate, a new and improved variety might be quickly formed on any one spot, and might there maintain itself in a body, so that whatever intercrossing took place would be chiefly between the individuals of the same new variety.
Each new form, also, as soon as it has been much improved, will be able to spread over the open and continuous area, and will thus come into competition with many others.
From these several considerations I think it inevitably follows, that as new species in the course of time are formed through natural selection, others will become rarer and rarer, and finally extinct.
So, though they were fagged more or less, and occasionally kicked or cuffed by the bullies, they were, on the whole, well off; and the fresh, brave school-life, so full of games, adventures, and good-fellowship, so ready at forgetting, so capacious at enjoying, so bright at forecasting, outweighed a thousand-fold their troubles with the master of their form, and the occasional ill-usage of the big boys in the house.
In fact, the solemn assembly, a levy of the School, had been held, at which the captain of the School had got up, and after premising that several instances had occurred of matters having been reported to the masters; that this was against public morality and School tradition; that a levy of the sixth had been held on the subject, and they had resolved that the practice must be stopped at once; and given out that any boy, in whatever form, who should thenceforth appeal to a master, without having first gone to some prepostor and laid the case before him, should be thrashed publicly, and sent to Coventry.
In the latter, the local or municipal authorities
form distinct and independent portions of the supremacy, no more subject, within their respective spheres, to the general authority, than the general authority is subject to them, within its own sphere.
Only by separating the two sources of cognition, related to one another as form to content, do we get the mutually exclusive and separately incomprehensible conceptions of freedom and inevitability.
Apart from these two concepts which in their union mutually define one another as form and content, no conception of life is possible.
Geometrical forms and arithmetical ratios furnish the laws according to which the world is created.
The doctrine which is assailed takes two or three forms, but fails in any of them to escape the dialectical difficulties which are urged against it.
Plato also left behind him a most potent instrument, the forms of logic-- arms ready for use, but not yet taken out of their armoury.
A crude conception of the ideas of Plato survives in the 'forms' of Bacon.
Coral islets are supposed to have been formed on the reef; and a ship is anchored in the lagoon-channel.
The instant this takes place, a perfect atoll is formed: I have said, remove the high land from within an encircling barrier-reef, and an atoll is left, and the land has been removed.
At Vanikoro, the lagoon-channel is remarkably deep, scarcely any alluvial soil has accumulated at the foot of the lofty included mountains, and remarkably few islets have been formed by the heaping of fragments and sand on the wall-like barrier reef; these facts, and some analogous ones, led me to believe that this island must lately have subsided and the reef grown upwards: here again earthquakes are frequent and very severe.
