Page 97 - ... the vaunted restoration of the Hippocratic method by Serapion, the pupil of Herophilus, in the empiric school which rejected reasoning altogether, and affected to rely upon experience. I pass over, also, the methodic school of Asclepiades, which attributed, after Democritus, all natural phaenomena to the fortuitous concourse of atoms, and the existence of bodies to the conjunction of these in a certain form, and their functions to the mechanical aggregation and separation of the same. Their doctrines...
Page 93 - MD.FRS, &c., late Fellow of Trinity College, and Professor of Anatomy in the University of Cambridge , with additional References furnished by the Author.
Page ix - Its objects are— to give a stronger impulse, and a more systematic direction to scientific enquiry— to promote the intercourse of those who cultivate Science in different parts of the British Empire with one another, and with Foreign Philosophers — to obtain a more general attention to the objects of Science, and a removal of any disadvantages of a public kind which impede its progress.
Page 315 - Are not gross bodies and light convertible into one another, and may not bodies receive much of their activity from th'e particles of light which enter their composition...
Page 255 - Water. And the Water rises up to this height by the Action only of those Particles of the Ashes which are upon the Surface of the elevated Water; the Particles which are within the Water, attracting or repelling it as much downwards as upwards. And therefore the Action of the Particles is very strong. But the Particles of the Ashes being not so dense and close together as those of Glass, their Action is not so strong as that of Glass, which keeps Quick-silver suspended to the height of 60 or 70 Inches,...
Page 296 - Were I to assume an hypothesis, it should be this, if propounded more generally so as not to determine what light is, further than that it is something or other capable of exciting vibrations in the aether ; for thus it will become so general and comprehensive of other hypotheses as to leave little room for new ones to be invented...
Page 534 - There are no perfectly hard inelastic bodies, as assumed by the earlier, and some modern writers on Mechanics. (3). The elasticity as measured by the velocity of recoil divided by the velocity of impact is a ratio, which, though decreasing as the velocity increases, is nearly constant, when the same rigid bodies are struck together with considerably different velocities. (4). The elasticity, as defined in (3), is the same whether the impinging bodies be great or small. (5). The elasticity is the...
Page 252 - The author finally remarks, that " Questions of this kind have of late largely engaged the attention of some French mathematicians, and the nature of their theories, and the results of the calculations founded on them, deserve to be brought as much as possible into notice.
Page 170 - J, quite independently of moulting. The difficulty of finding specific characters for birds which shall be applicable to both sexes and all ages, particularly in those groups in which the changes of plumage above alluded to are most prevalent, has been severely felt by ornithologists. Mr. Macgillivray...
Page 298 - I am disposed to believe that the luminiferous ether pervades the substance of all material bodies, with little or no resistance, as freely, perhaps, as the wind passes through a grove of trees.
