Schleiden had even supposed the nucleus to be a constituent part of the wall, sometimes lying enclosed between two layers of its substance, and Schwann quoted this view with seeming approval. Schwann believed, however, that in the mature cell the nucleus ceased to be functional and disappeared.
Well, under these circumstances he felt that the case was quite clear, and that the mercury was not what it had appeared to M. Schwann to be, a bar to the admission of these organisms; but that, in reality, it acted as a reservoir from which the infusion was immediately supplied with the large quantity that had so puzzled him.
A troop of observers soon entered upon the study of the nerves, and the leader here, as in so many other lines of microscopical research, was no other than Theodor Schwann. Through his efforts, and with the invaluable aid of such other workers as Remak, Purkinje, Henle, Muller, and the rest, all the mystery as to the general characteristics of nerve tracts was cleared away.
Schwann burdened his enunciation of the "cell theory" with two false suppositions; the one, that the structures he called "nucleus" and "cell-wall" are essential to a cell; the other, that cells are usually formed independently of other cells; but, in 1839, it was a vast and clear gain to arrive at the conception, that the vital functions of all the higher animals and plants are the resultant of the forces inherent in the innumerable minute cells of which they are composed, and that each of them is, itself, an equivalent of one of the lowest and simplest of independent living beings the Torula.
But when Turpin and Schwann resolved the living body into an aggregation of quasi-independent cells, each, like a Torula, leading its own life and having its own laws of growth and development, the aggregation being dominated and kept working towards a definite end only by a certain harmony among these units, or by the superaddition of a controlling apparatus, such as a nervous system, this conception ceased to be tenable.
It was needful to repeat the experiments under conditions which would make sure that neither the oxygen of the air, nor the composition of the organic matter, was altered in such a manner as to interfere with the existence of life. Schulze and Schwann took up the question from this point of view in 1836 and 1837.
"Made a mistake, eh?" The giantess started. "Ah! he is better," said a treacherous voice. It was Robeccal who spoke. He feared lest his absence would look badly, and he had come back. "A physician is wanted," exclaimed Fanfar, turning to Schwann, who was weeping like a child. "There is none in the village, none nearer than Vagney, a league away." "Then I will go for him." "But the inundation.
The yacht is to be hired for a week, or longer if necessary, and used only to-night. Behold the wonderful good-fortune of the affair! It is I who have been selected by my master to proceed to Monaco to make arrangements with the German, Herr Schwann. I am on my way there at the moment." "A yacht?" Hunterleys repeated. "There are wonderful things to be thought of," Frenhofer asserted eagerly.
In a louder voice he said: "Then, comrade, we will accept your offer, and go with you to Rémisemont to-morrow." Gudel nodded, then called Fanfar. "To work, my lad," he cried. "We must stir up these excellent people in this village. Schwann, where is my permit from the mayor?" Schwann hurried in wiping his hands, and from under a pile of plates he drew out a paper.
It appears to me that this is a deliberate plot. The yacht which I and my friends thought that we were boarding to-night was the Christabel, which my servant had instructions to hire from Schwann of Monaco. I await some explanation from you, sir, as to your purpose in sending your pinnace to the landing-stage of the Villa Mimosa and deliberately misleading us as to our destination?"
