Du Moncel on the induction spark, and during the course of which he, in 1853, discovered that phenomenon of the electric efflux which has since been the object of important researches on the part of several physicists and chemists, among whom must be cited Messrs. Thenard, Hautefeuille, and Chapuis. Twenty years ago, Mr.
The power of spongy platinum to cause the combination of oxygen and hydrogen had been discovered by Dobereiner in 1823, and had been applied by him in the construction of his well-known philosophic lamp. It was shown subsequently by Dulong and Thenard that even a platinum wire, when perfectly cleansed, may be raised to incandescence by its action on a jet of cold hydrogen.
This personage, who was as soberly dressed as an archbishop, and had altogether a pontifical air, raised himself to his feet and approached the visitor. "Has monsieur an appointment " "No," said Adams. "I have come to see your master on business. You can take him my card yes, that one Dr. Adams, introduced by Dr. Thénard."
The sporting nature of the proposal coming from the sedate Thénard rather tickled him. "He wants to pit me against this Berselius," said Adams to himself, "same as if we were dogs. That's the long and short of it. Yes, I can understand his meaning in part; he's afraid if Berselius engages some week-kneed individual, he'll give the weak-kneed individual more than he can take.
Then there's the two thousand francs a month, and not a penny out of pocket, and there's the Congo, and the guggly-wuggly alligators, and the great big hairy apes, and the feel of a gun in one's hand again. Oh, my!" "All the same, it's funny," he went on, as he drew near the Boulevard St. Michel. "When Thénard spoke of Berselius there was something more than absence of friendship in his tone.
There would, without doubt, have been severe inflammation of the brain, but for Berselius's splendid condition at the time of the accident, and the fact that Adams had bled him within an hour of the injury. Thénard had relieved the pressure by operation, but there was great weakness. It was impossible to say what the result would be yet. "Has he regained consciousness?"
Adams had no part in the proceedings except as a looker-on. No man could assist Thénard in an operation who was not broken to the job, for, when operating Thénard became quite a different person to the every-day Thénard of lecture room and hospital ward.
Maxine rose to meet him. She read both good and bad news in his face. "The operation has been successful, but there is great weakness." He rolled an armchair for her to sit down, and then he told her as much as she could understand. Thénard had found a slight depression of the inner table of the skull, and some congestion and thickening of the dura mater. It all dated from the accident.
At twelve o'clock that night, Maxine was seated in the library, with a book which she had been vainly trying to read face downward on the floor beside her. Thénard, his assistant surgeon, and two nurses, had arrived shortly after ten. Operating table, instruments, everything necessary had been brought, set up, and fixed by Thénard's own man.
So far back as 1803, Thénard pointed out, in most distinct terms, the important fact that yeast contains a nitrogenous "animal" substance; and that such a substance is contained in all ferments. Before him, Fabroni and Fourcroy speak of the "vegeto-animal" matter of yeast.
