Page 370 - them into an insulated inductor, connected to one pair of quadrants of an electrometer. The other pair of quadrants, the case of the electrometer, and the screen inside which the inductor was placed, were connected to earth. The hydrogen was bubbled through a strong solution of caustic potash and the chlorine through water, before entering the inductor.
Page 487 - that the chief food of the corals consists of the abundant pelagic life of the tropical regions " does not seem to rest upon many direct observations, though the same statement is repeated, or inferred, by nearly all writers on the theory of the formation of these reefs. A further conclusion is 1
Page 290 - Maxwell then proceeds to state, giving a reference to Faraday, that if, during the action of the inducing force, the apparent electrification of the surface be discharged by passing a flame over the surface, then, when the inducing force is taken away, there will appear a true electrification opposite to
Page 430 - and Tinoporus). It covers a considerable area of the islands, and has accumulated during the memory of the inhabitants to such an extent as to silt up certain parts of the lagoon. This and the abundant growth of corals and calcareous algae, such as Halimeda, lead to the belief that the lagoon is slowly filling up.
Page 407 - B was connected to one pair of quadrants of an electrometer, the other pair being connected to earth.
Page 193 - will possess the required relation. Let now ft and f be two other screws (not reciprocal); we may consider the question as to whether a rigid body can be designed and placed so that
Page 337 - The piston then rises till the pressure in A only differs from the atmospheric pressure by that required to support the weight of the piston, — a small fraction of a millimetre of mercury and negligible in these experiments. If B be the barometric pressure, then the pressure of the air before expansion is
Page 374 - hydrochloric acid, nitric acid, aqua regia and potash solution. The action of hydrofluoric acid removes it apparently by dissolving the glass. These tests indicate carbon rather than silicon, but the quantity of the stain is too small to make certain. The stain is also formed on screens of mica, quartz and calcite; and
Page 499 - much more favourable for the latter than the former. " If the barrier increases one foot in height in a century, the inner reef, according to this supposition, would increase but half a foot; and any rate of subsidence between the two mentioned, would sink the inner reefs more rapidly than they could grow and cause them to disappear'.
Page 143 - acid. (3) On the atomic weight of Oxygen. By A. SCOTT, MA, Trinity College. Mr Scott gave a short account of the present state of our knowledge as to the atomic weight of oxygen, and said that it might be regarded as conclusively proved that if H = 1,
