Page 205 - A young man, a Mr. Davy, at Dr. Beddoes', who has applied himself much to chemistry, has made some discoveries of importance, and enthusiastically expects wonders will be performed by the use of certain gases, which inebriate in the most delightful manner...
Page 206 - Nature has thrown over the operations and properties of ethereal fluids. Galvanism I have found, by numerous experiments, to be a process purely chemical, and to depend wholly on the oxidation of metallic surfaces, having different degrees of electric conducting power. Zinc is incapable of decomposing pure water ; and if the zinc plates be kept moist with pure water, the galvanic pile does not act...
Page 208 - I ventured to conclude from the general principles on which the phenomena were capable of being explained, that the new methods of investigation promised to lead to a more intimate knowledge than had hitherto been obtained, concerning the true elements of bodies. "This conjecture, then sanctioned only by strong analogies, I am now happy to be able to support by some conclusive facts.
Page 188 - ... const. Here Q(T> represents the heat absorbed by the progress of the reaction at the temperature in question. If therefore Q(T> is positive, or the reaction is endothermic, K is diminished with the rise in temperature and the change shown in the above equation proceeds from left to right. The work described in the present paper was undertaken with the object of seeing how far these theoretical considerations can be applied practically, and also of preparing pure metals or lower oxides of metals...
Page 125 - Lowry (1907, p. 125) suggested that the affinity of the "ionic nucleus'' for water is the main source of the energy required.
Page 210 - ... grains in weight, the whole was covered, by a film of naphtha, and the plate was made positive, and the mercury negative, by a proper communication with the battery of five hundred. The amalgams obtained in this way, were distilled in tubes of plate glass, or in some cases in tubes of common glass. These tubes were bent in the middle, and the extremities were enlarged, and rendered globular by...
Page 55 - for welding purposes. | He finds that metallic calcium is a still more powerful reducing agent than aluminium. For example, when molecular proportions of aluminium and ferric oxide are mixed together and ignited by means of a fuse of aluminium and barium peroxide, intense reaction ensues, and continues until all the oxygen has been removed from the ferric oxide, and aluminium oxide and metallic iron produced in its stead. When metallic calcium in the form of fine turnings is mixed with ferric oxide...
Page 206 - Beddoes', who has applied himself much to chemistry, has made some discoveries of importance, and enthusiastically expects wonders will be performed by the use of certain gases, which inebriate in the most delightful manner, having the oblivious effects of Lethe, and at the same time giving the rapturous sensations of the Nectar of the Gods ! Pleasure even to madness is the consequence of this draught.
Page 208 - In the Bakerian Lecture which I had the honour of presenting to the Royal Society last year, I described a number of decompositions and chemical changes produced in substances of known composition by electricity, and I ventured to conclude from the general principles on which the phenomena were capable of being explained, that the new methods of investigation promised to lead to a more intimate knowledge than had hitherto been obtained, concerning the true elements of bodies.
