Jest run slap bang into rich relations. How much is the doctor wuth? He never met me, but they say Deville is a choice mackerel, for a Frenchman. I was about to say, I went down to Cinc'natti on the Enterprise last December. Best boat on the river, Captain Shreve says, and the fourth one built. I have saw the Orleens, the Comet and the Vesuvius, but the Enterprise knocks 'em all.
This, then, is the principle of the manufacture and production of platinum in the old way. The treatment which Deville proposes to carry out, and which he has carried out to a rather large extent in reference to the Russian supply of platinum, is one altogether by heat, having little or no reference to the use of acids.
The discoveries of Sainte-Claire Deville have brought many chemical phenomena into a similar category, and reactions such as solution, which used to be formerly the type of an irreversible phenomenon, may now often be effected by sensibly reversible means.
I have here a source of coal-gas; there I have a source of hydrogen; and here I have a source of oxygen. I have here also one of the blowpipes used by Deville in his process for working platinum in the way I have spoken of. There are two pipes, and one of them goes to the source of coal-gas, and the other to the supply of oxygen.
We shall now shew you this same process of boiling the silver, cast on a screen from the electric lamp which you have before you; and while Dr. Tyndall is kindly getting the lamp ready for this purpose, let me tell you that Deville proposes to throw out in this way all these extraneous things that I have spoken of, except two namely, iridium and rhodium.
What object had these unknown watermen in conveying their unwilling passengers away from communication with Captain Winslow and Doctor Deville? Evaleen could not hide her dismay. Lucrèce grew desperate. "Will you stop the boat, sir? I beg it as a favor. I must go back to mon père. He will think us drowned. I must find him." "Keep cool, miss.
It is not intended at present to discuss the necessity of tenuity with reference to the functions of the sun as a radiator; yet it will be proper to observe that on merely dynamical grounds the enormous density of the solar envelope which would result from low temperature presents an unanswerable objection to the assumption of Pouillet, Vicaire, Sainte-Claire Deville, and other eminent savants, that the temperature of the solar surface does not reach 3,000° C.
The new castle was commenced after the plague of 1632 from the designs of the Frenchman Deville, who used the material of the theatre. Kandler says that he remembered this castle, which had double walls with four towers to each, and one larger tower towards Monte Maggiore. The present castle is quite modern, and one is warned off when approaching it. The mediæval walls were demolished in 1848.
Are there stores of these things at the principal stations of the Transcaspian? Not at all. They have simply put in practice an idea which occurred to our great chemist, Sainte-Claire Deville, when first petroleum was used in France.
Rouen has also its mineral waters, which, even in the neighbouring towns, have a sort of reputation, I will point out three of the principal sources, after Lepecq de la Clôture: The first, to the east, is known under the name of la Marèquerie, to which we arrive by the rue Martainville; the second, to the south east, named de Saint-Paul; the third is situated at Déville, in the neighbourhood of Rouen.
