Before the material commences to circulate the configuration is already virtually traced, the courses of the plastic currents are already mapped out.

The stones of our buildings co-ordinate according to the considered plan of the architect; they form an ideal assemblage before they exist as a concrete assemblage.

The genesis of living creatures offers to our contemplation an infinity of wonders far greater than this matter of a locust's wing; but in general they pass unperceived, obscured as they are by the veil of time.

I have heard that a learned inquirer, for whom life is only a conflict of physical and chemical forces, does not despair of one day obtaining artificially organisable matter--_protoplasm_, as the official jargon has it.
