Page iii - Angularity of the subjects, or the advantageous manner of treating them, without pretending to answer, or to make the Society answerable, for the certainty of the facts, or propriety of the reasonings, contained in the several Papers so published, - which must still rest on the credit or judgment of their respective Authors.
Page 68 - Bprt, (I) where t is the difference of temperature between the surface and the fluid, p is the density of the fluid, v its velocity, and A and B constants depending on the nature of the fluid, H being the heat transmitted per unit of surface of the surface in a unit of time.
Page iii - And this seems principally to have been done with a view to satisfy the public that their usual meetings were then continued, for the improvement of knowledge and benefit of mankind : the great ends of their first institution by the Royal Charters, and which they have ever since steadily pursued.
Page 322 - Special Appliances and Preliminaries of the Research. 12. Having convinced myself by preliminary designs, not only of the practicability of the appliances, but also of the possibility of their inclusion in the already much occupied space adjacent to the brake, there still remained much to be done in the way of experimental investigation to obtain data from which the requisite proportions of these appliances could be determined, and these preliminary investigations were not commenced till the summer...
Page 322 - Fahr. above that of the laboratory, these would probably amount to two or three per cent. of the total heat. (6) Scales for greater facility and accuracy in weighing the water, with a switch actuated by the counter. (7) A pressure gauge or barometer, by which the standard pressure for the boiling point might be readily determined at 3° or 4° Fahr.
Page 263 - ... such for example as gravitational or magnetic forces. Of the remainder of the energy, which arises from the mutual actions of neighbouring molecules, a regular, or organised, part can be separated out which represents the energy of elastic stress and is a function of the deformation of the element of volume treated as a whole.
Page 171 - The light from a square, or a disc, or an oblong, just before extinction, is a fuzzy patch of grey, and appears finally to depart almost as a point. This can scarcely account for the smallest width of an illuminated surface determining the intensity of the light just not visible ; but it tells us that the light is still exercising some kind of stimulus on the visual apparatus, even when all sensation of light is gone from the outer portions. The fact that the disappearance of the image takes place...
Page 260 - This method consists essentially in computing the forcive by combining opposed poles of neighbouring elements, instead of taking the single polarised element as the unit ; it shows that these adjacent poles nearly compensate each other, except as regards a simple volume density whose attraction has no molecular part, and a surface density, partly at the outer surface and partly at the surface of the cavity which contains the point under consideration. The effect of the latter surface density, depending...
