Page 955 - The whole train of animated beings, from the simplest and oldest up to the highest and most recent, are, then, to be regarded as a series of advances of the principle of development, which have depended upon external physical circumstances, to which the resulting animals are appropriate.
Page 988 - The length of a male specimen, somewhat less than nine feet in expanse, was three feet three inches from the tip of the beak to the extremity of the tail ; and its height, when perching, with the neck partly withdrawn, two feet eight inches.
Page 957 - ... that the simplest and most primitive type, under a law to which that of like-production is subordinate, gave birth to the type next above it, that this again produced the next higher, and so on to the very highest, the stages of advance being in all cases very small- — namely, from one species only to another ; so that the phenomenon has always been of a simple and modest character.
Page 956 - Remembering these things, we are drawn on to the supposition, that the first step in the creation of life upon this planet was a chemico-electric operation, by which simple germinal vesicles were produced.
Page 956 - ... have already seen that this nucleated vesicle is itself a type of mature and independent being in the infusory animalcules, as well as the starting point of the foetal progress of every higher individual in creation, both animal and vegetable.
Page 955 - In what way was the creation of animated beings effected ? The ordinary notion may, I think, be not unjustly described as this, — that the Almighty author produced the progenitors of all existing species by some sort of personal or immediate exertion. But how does this notion comport with what we have seen of the gradual advance of species, from the humblest to the highest?

Page 958 - Thus he thought that a bird would be driven by necessity to seek its food in the water, and that, in its efforts to swim, the outstretching of its claws would lead to the expansion of the intermediate membranes, and it would thus become webfooted. Now it is possible that wants and the exercise of faculties have entered in some manner into the production of the phenomena which we have been considering; but certainly not in the way suggested by Lamarck, whose whole notion is obviously so inadequate...
Page 908 - ... liberty of other quadrupeds. Often, in the middle of the night, when all my people have been fast asleep around the fire, have I stood to contemplate these faithful animals lying by their side, and have learnt to esteem them for their social inclination to mankind.
Page 1200 - Herrick states,* that, in this part of the country, a very large proportion, probably more than nine tenths, of every generation of this fly is thus destroyed. One of these parasites was made known by Mr. Say, in the first volume of the " Journal of the Academy of Natural Sciences of Philadelphia " ; and the interesting discovery of three more kinds is due to the exertions of Mr.
