A cruse of oil was brought forward and poured into a saucepan, which was previously turned upside down, to show that there was no water in it.
The alleged reason for this step was, that the vulgar conjurors, who profess to drink boiling oil, place the oil in water, and drink it when the water boils, at which time the oil is not warmer than an ordinary cup of tea.

He intended to drink the oil when any person might see it bubbling in the saucepan, and when the thermometer would prove that it was heated to three hundred and sixty degrees.

The saucepan was accordingly placed on the fire, and as it was acquiring the requisite heat, the fire-king challenged any man living to drink a spoonful of the oil at the same temperature as that at which he was going to drink it.

In a few minutes afterwards, he sipped off a spoonful with greatest apparent ease, although the spoon, from contact with the boiling fluid, had become too hot for ordinary fingers to handle.
"And now, Monsieur Smith," said the fire-king, "now for your challenge.
Have you prepared yourself with phosphorus, or will you take some of mine, which is laid on that table ?" Mr.Smith, walked up to the table, and pulling a vial bottle out of his pocket, offered it to the poison-swallower.
Fire-king--"I ask you, on your honor as a gentleman, is this genuine unmixed poison ?" Mr.Smith--"It is, upon my honor." Fire-king--"Is there any medical gentleman here who will examine it ?" A person in the room requested that Dr.Gordon Smith, one of the medical professors in the London University, would examine the vial, and decide whether it contained genuine phosphorus.
The professor went to the table, on which the formidable collection of poisons--such as red and white arsenic, hydrocyanic acid, morphine and phosphorus--was placed, and, examining the vial, declared, that, to the best of his judgment, it was genuine phosphorus.
M.Chabert asked Mr.Smith, how many grains he wished to commence his first draught with.

Mr.Smith--"Twenty grains will do as a commencement." A medical gentleman then came forward and cut off two parcels of phosphorus, containing twenty grains each.
