Page 318 - The consequences of these clear and general principles of physiological energetics are of the greatest importance from a practical as well as from a theoretical point of view.
Page 9 - ... persons who have been or who are going to be passengers on the railway, its employment does not become ultra vires because in use as a commercial matter passengers are not refused whose conveyance will add something to the profits or diminish something of the loss upon the working of the omnibuses. A good deal of discussion has taken place as to whether the company can obtain the license of the corporation to run omnibuses except upon the terms that they shall be bound to take any person on their...
Page 404 - ... it places its cocoon. Several of these caterpillars unite together, and selecting a long and vigorous immature shoot or leader of the orange tree they kill it by cutting into its base until it wilts and bends over. The leaves of a young shoot, in drying, turn a light tan-color, which harmonizes most perfectly with the hairy locks of the caterpillar covering the cocoon. The latter is, consequently, not easily detected, even wbeu placed upon the exposed and. upturned surface of the leaf.
Page 403 - Hag-moth larvae do not seek to hide away their cocoons, but attach them to leaves and twigs fully exposed to view, with, however, such artful management as to surroundings and harmonizing colors that they are of all the group the most difficult to discover. A device to which this insect frequently resorts exhibits the extreme of instinctive sagacity. If the caterpillar can not fin:!
Page 573 - That which they make when disturbed mimics a nest of young snakes or young birds under similar circumstances, a sort of scream.

Page 176 - Such a column is of enormous length, and contains many thousands if not millions of individuals. I have sometimes followed them up for two or three hundred yards without getting to the end. They make their temporary habitations in hollow trees, and sometimes underneath large fallen trunks that offer suitable hollows. A nest that I came across in the latter situation was open at one side. The ants were clustered together in a dense mass, like a great swarm of bees, hanging from the roof, but reaching...
Page 351 - In Tropical South America a numerous series of gaily-coloured butterflies and moths, of very different families, which occur in abundance in almost every locality a naturalist may visit, are found all to change their hues and markings together, as if by the touch of an enchanter's wand, at every few hundred miles, the distances being shorter near the eastern slopes of the Andes than nearer the Atlantic. So close is the accord of some half dozen species (of widely different genera) in each change...
Page 176 - ... of ants, others the legs and dissected bodies of various insects. I was surprised to see in this living nest tubular passages leading down to the centre of the mass, kept open just as if it had been formed of inorganic materials. Down these holes the ants who were bringing in booty passed with their prey. I thrust a long stick down to the centre of the cluster, and brought out clinging to it many ants holding larvœ and pupas, which probably were kept warm by the crowding together of the ants.
