Page 110 - ... of any gradual diminution of the size — of such species, but is the result of circumstances which may be illustrated by the fable of the " Oak and the Reed; " the smaller and feebler animals have bent and accommodated themselves to changes to which the larger species have succumbed.

Page 112 - Devonian aeons, because the explored parts of such strata have been deposited from an ocean, and the chance of finding a terrestrial and air-breathing creature's remains in oceanic deposits is very remote. But, in the present state of the warm-blooded, air-breathing, viviparous class, no genera and species are represented by such numerous and...
Page 534 - Led by his own beautiful researches, and quite independent: of Mayer, Mr. Joule published his first Paper on the 'Mechanical Value of Heat,' in 1843 ; but in 1842 Mayer had actually calculated the mechanical equivalent of heat from data which a man of rare originality alone could Him to account. From the velocity of sound in air Mayer determined the mechanical equivalent of heat. In 1845 he published his Memoir on ' Organic Motion,' and applied the mechanical theory of heat in the most fearless and...

If a dry season be gradually prolonged, the large mammal will suffer from the drought sooner than the small one; if such alteration of climate affect the quantity of vegetable food, the bulky herbivore will first feel the effects of stinted nourishment; if new enemies be introduced, the large and conspicuous animal will fall a prey while the smaller kinds conceal themselves and escape.
Page 152 - Again, certain well marked forms of living beings have existed through enormous epochs, surviving not only the changes of physical conditions, but persisting comparatively unaltered, while other forms of life have appeared and disappeared. Such forms may be termed " persistent types " of life ; and examples of them are abundant enough in both the animal and the vegetable worlds.
Page 162 - By proper mechanical arrangemi-ills this cylinder could be revolved, and the part which was at one instant within, rapidly brought to the outside, and observed by the audience. As the cylinder could be made to revolve 300 times in a second, and as the twentieth part of a revolution was enough to bring a sufficient portion of the cylinder to the outside, it is evident that a phosphorescent effect which would last only the l-3000th or even the l-6000th of a second might be made apparent.
Page 200 - Ah my God, What might I not have made of thy fair world, Had I but loved thy highest creature here ? It was my duty to have loved the highest: It surely was my profit had I known : It would have been my pleasure had I seen. We needs must love the highest when we see it, Not Lancelot, nor another.
Page 534 - ... combustion was sacrificed by the sun to form that bit of cotton. But we cannot stop at vegetable life, for this is the source, mediate or immediate, of all animal life. The sun severs the carbon from its oxygen ; the animal consumes the vegetable thus formed, and in its arteries a reunion of the severed elements takes place, and produces animal heat.
