He had been persecuted by Paul II. for taking part in the famous banquets, savouring oddly of Paganism, of Pomponius Lætus; but the late Pontiff Sixtus IV. had taken him into his favour together with Platina, one of his fellow-sufferers in the castle of Saint Angelo.
Marble quarries, mines of salt, platina, gold, and coal are worked here on a large scale. Although Perm, by its situation, has become an important town, it is by no means attractive, being extremely dirty, and without resources. This want of comfort is of no consequence to those going to Siberia, for they come from the more civilized districts, and are supplied with all necessaries.
Mountains suffer degradation and wear away, and with them the metallic veins which they contain. The hardest rock is worn into impalpable mud, the ordinary metals oxidate, and both are removed; but gold, platina, and a few others are nearly indestructible, and from their weight, sinking to the bottom, are left behind.
When the machine is not in use, let the metals be removed from the fluid; and, if not to be soon again used, let them be rinsed with water, carefully avoiding to wet the wooden bar in which the platina is set.
The muriate of gold or platina, formed by digesting these metals in nitro-muriatic acid, must be entirely free from all excess of acid; because it will otherwise act too forcibly on the steel, and cause the coating of gold to peel off.
When the communication between the points positively and negatively electrified was made in the air rarefied in the receiver of the air-pump, the distance at which the discharge took place increased as the exhaustion was made; and when the atmosphere in the vessel supported only one-fourth of an inch of mercury in the barometrical gauge, the sparks passed through a space of nearly half an inch; and, by withdrawing the points from each other, the discharge was made through six or seven inches, producing a most brilliant coruscation of purple light; the charcoal became intensely ignited, and some platina wire attached to it fused with brilliant scintillations and fell in large globules upon the plate of the pump.
With these instruments, they made four observations of latitude at Dunkirk, Paris, Evaux, Carcassonne, and Barcelona; two bases measured near Melun and Perpignan, with rules of platina and copper, forming metallic thermometers, were connected with the triangles of the meridian line: the total interval, which was 9 deg..6738, was found to be 551584.72 toises.
In 1468 a grave charge of conspiracy against the Pope's life and of organising a schism led to the arrest of Pomponius and Platina, some of the more wary members of the compromised fraternity saving themselves by timely flight.
It is on this principle, too, that the small concentrated residues of great operations in the arts are almost sure to be the lurking places of new chemical ingredients: witness iodine, brome, selenium, and the new metals accompanying platina in the experiments of Wollaston and Tennant. It was a happy thought of Glauber to examine what everybody else threw away.”
For that reason, also, Pope Pius is reported to have said that there were certain reasons why marriage was taken away from priests, but that there were far weightier ones why it ought to be given back; for so Platina writes. Since, therefore, our priests were desirous to avoid these open scandals, they married wives, and taught that it was lawful for them to contract matrimony.
