Sivu 19 - The sixth, and of creation last, arose With evening harps and matin; when God said, Let the Earth bring forth soul living in. her kind, Cattle, and creeping things, and beast of the Earth, Each in their kind.
Sivu 19 - As from his lair, the wild beast where he wons In forest wild, in thicket, brake, or den.
Sivu 96 - ... should expect to see it appear under forms of great simplicity, endowed, like existing Fungi, with the power of determining the formation of new protoplasm from such matters as ammonium carbonates, oxalates and tartrates, alkaline and earthy phosphates, and water, without the aid of light. That is the expectation to which analogical reasoning leads me ; but I beg you once more to recollect that I have no right to call my opinion anything but an act of philosophical faith.
Sivu 95 - With organic chemistry, molecular physics, and physiology, yet in their infancy, and every day making prodigious strides, I think it would be the height of presumption for any man to say that the conditions under which matter assumes the properties we call " vital " may not, some day, "be artificially brought together.
Sivu 19 - The tawny lion, pawing to get free His hinder parts — then springs, as broke from bonds, And rampant shakes his brinded mane; the ounce, The libbard, and the tiger, as the mole Rising, the crumbled earth above them threw In hillocks...
Sivu 95 - But expectation is permissible where belief is not ; and if it were given to me to look beyond the abyss of geologically recorded time to the still more remote period when the earth was passing through physical and chemical conditions, which it can no more see again than a man...
Sivu 97 - ... welfare ; blind to the richest sources of beauty in God's creation; and unprovided with that belief in a living law, and an order manifesting itself in and through endless change and variety, which might serve to check and moderate that phase of despair through which, if he take an earnest interest in social problems, he will assuredly sooner or later pass.
Sivu 95 - ... recorded time to the still more remote period when the earth was passing through physical and chemical conditions, which it can no more see again than a man can recall his infancy, I should expect to be a witness of the evolution of living protoplasm from not living matter. I should expect to see it appear under forms of great simplicity, endowed, like existing fungi, with the power of determining the formation of new protoplasm, from such matters as ammonium carbonates, oxalates and tartrates,...
Sivu 8 - The register of knowledge of fact is called history :. Whereof there be two sorts: one called natural history, which is the history of such facts, or effects of nature, as have no dependence on man's mill, such as are the histories of metals, plants, animals, regions, and the like. The other is civil history, which is the history of the voluntary actions of men in commonwealths.
Sivu 72 - If he does not do so, he may read till the crack of doom, but he will never know much about chemistry. That is what every chemist will tell you, and the physicist will do the same for his branch of science. The great changes and improvements in physical and chemical scientific education, which have taken place of late, have all resulted from the combination of practical teaching with the reading of books and with the hearing of lectures. The same thing is true in Biology. Nt>body will ever know anything...
