It is particularly remarkable, that according to the above-mentioned gentleman's essay on the Decomposition and Composition of the fixed alkalies, in the Philosophical Transactions (a copy of which essay he has just favoured me with) it appears that " the largest quantity of oxygen indicated by these experiments was for potash 17, and for soda, 26 parts in 100, and the smallest 13 and 19.
258. oldal - I was induced by some observations I had previously made upon the burning of coal, to try the combustible property of the gases produced, from it, as well as from peat, wood, and other inflammable substances. And being struck with the great quantities of gas which they afforded, as well as...
116. oldal - A small piece of pure potash, which had been exposed for a few seconds to the atmosphere, so as to give conducting power to the surface, was placed upon an insulated disc of platina, connected with the negative side of the battery of the power of...
167. oldal - When the basis of soda is exposed to the atmosphere, it immediately tarnishes, and by degrees becomes covered with a white crust, which deliquesces much more slowly than the substance which forms on the basis of potash. It proves, on minute examination, to be pure soda. The basis of soda combines with...

In the synthesis, on the contrary, the natural energies or attractions come in equilibrium with each other ; and when these are in a low state at common temperatures, a slow combination is effected ; but when they are exalted by heat, a rapid union is the result ; and as in other like cases with the production of fire. — A number of...
130. oldal - On naphtha colourless and recently distilled, as I have already said, it has very little power of action ; but in naphtha that has been exposed to the air it soon oxidates, and alkali is formed, which unites with the naphtha into a brown soap that collects round the globule. On the concrete oils (tallow, spermaceti, wax, for instance), when heated, it acts slowly, coaly matter is deposited, a little...

When plunged, by proper means, beneath the surface of the acids, it is rapidly oxygenated; soda is produced, and the other educts are similar to those generated by the action of the basis of potash. With respect to the fixed and volatile oils and naphtha in their different states, there is a perfect coincidence between the effects...
