Σελίδα 81 - Cereopsia-goose has bred at the Zoological Gardens every February for five or six years. Among migratory birds, also, it has been observed that when they are kept in confinement, and removed from all the circumstances that might be supposed to induce or necessitate their journeys, they yet become restless at the return of the season for their migration. In these and the like facts there appear indications of a chronometry in the organic processes of warmblooded animals, which corresponds with that...
Σελίδα 80 - In these the varieties of seasons have less influence in modifying the rate, as well as all the other measures, of life ; and the less influence, the higher the species, or the degree of development of the individual. Moreover, there are in birds some instances in which organic processes have a tendency to observe certain times of the year even when the seasons are changed. Thus among those brought from Australia to this country, some of the parakeets breed here in December ; the black swan sometimes...
Σελίδα 69 - ... gradually worn out, as if there were a gradual consumption of a store of material or of force ; but that, as, at a set time, the development of the body ceases and growth goes on, and then growth ceases and the body is only maintained in- its perfection, so, after a time of such maintenance, the method of the formative processes in the body changes, it slowly degenerates, and through degeneracy dies. And all these stages are, alike, natural, constant, timely ; all, too, are together, characteristic...
Σελίδα 78 - February of the year ensuing, and the remainder not before the sairte month in the third year." (Vol. iii. p. 264.) The design of so singular an arrangement is, as they observe, to secure that insects, coming into active life in February or March, may not be utterly exterminated by the ungenial weather of a single season, or of two...
Σελίδα 81 - And, if it be so, these might form a group offsets, in addition to those of the diurnal variations of the organic processes, in which vital changes are set to the same rules of time as changes of the surface of the earth, yet have their own proper laws ; and concerning which it might be said, that the cycles of life, and of the earth do, indeed, correspond, but only as concentric circles do, which are drawn round one centre, but are not connected, except in design and mutual fitness. But, however...
Σελίδα 78 - Dens Canis, from the same gardens, the plants of which, growing side by side in the same bed, always present a similar difference in their times of flowering, &c., though in all other respects alike.] It would be difficult to imagine a variety thus marked only by a peculiarity in rate of living, if temperature, or the influence of the seasons, alone determined the rate of life in the species. The simplest explanation seemed to be that, as there may be varieties in size and number of organs, and almost...
Σελίδα 81 - ... restless at the return of the season for their migration. In these and the like facts there appear indications of a chronometry in the organic processes of warm-blooded animals, which corresponds with that of the seasons, but is essentially independent. And, if it be so, these might form a group of facts, in addition to those of the diurnal variations of the organic processes, in which vital changes are set to the same rules of time as changes of the surface of the earth, yet...
Σελίδα 75 - to a method of nutrition in which the acting parts are, at certain periods, raised with time-regulated progress to a state of instability of composition from which they then decline, and in their decline may change their shape and move with a definite velocity, or (as nervous centres) may discharge...
Σελίδα 126 - ... be no more morbid change than that of softening of the walls of vessels, and the small quantity of connective tissue, which naturally hold together the two parts. A greater change is effected when articular cartilage can be stripped from bone ; for here the separation is not possible till after the ulceration or extreme softening of one or both of the adjacent layers. In some of these cases it is observable that the disseverance of the bone and cartilage is without apparent formation of pus,...
Σελίδα 75 - ... nutrition, in which the acting parts are, at certain periods, raised, with time-regulated progress, to a state of instability of composition, from which they then decline, and in their decline may change their shape and move with a definite velocity, or (as nervous centres) may discharge nerve-force." And this would be still maintained; but whether it were true or not, the rhythmical nutrition of rhythmically-acting muscles would be certain. If not a cause, it must be a consequence of such acting;...
