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.
We cannot better sum up the whole tendency of the construction of mechanical theories on these last lines than in the words of Schwann: “There is within the organism no fundamental force working according to a definite idea; it arises in obedience to the blind laws of necessity.” So much for the different lines followed by the mechanical theories of to-day.
"That is precisely what I mean!" answered Bobichel, forgetting all caution. La Roulante rushed at him. Caillette threw herself between them, and Schwann dragged her back. La Roulante caught Caillette by the arm and swung her off, then the girl picked herself up and ran to Gudel's bed. "Help! father!" she cried, "help!" The girl's voice seemed to produce a magical effect.
Schwann had returned to his saucepans. "Well?" said the soldier, leaning over his glass as if to smell the wine. "All goes well," answered Gudel. "The grain was well sown the harvest waits." "We will talk elsewhere. Did you notice that fellow who sat reading over there in the corner?" "Yes a bad face. A lacquey, I think." "A lacquey or a spy. Look out for him!
==The Cell Doctrine==. The cell doctrine is, in brief, the theory that the bodies of animals and plants are built up entirely of minute elementary units, more or less independent of each other, and all capable of growth and multiplication. This doctrine is commonly regarded as being inaugurated in 1839 by Schwann.
It is just fifty years since Schwann and others proved that, even with respect to them, the supposed evidence of abiogenesis was untrustworthy.
From purely morphological investigations, Turpin and Schwann, as we have seen, arrived at the notion of the fundamental unity of structure of living beings. And, before long, the researches of chemists gradually led up to the conception of the fundamental unity of their composition.
Within the course of an hour I shall transfer ten thousand francs to the account of François Frenhofer at the English Bank here." The eyes of the man seemed suddenly like pinpricks of fire. "Monsieur is a prince," he murmured. "And now for the further details. If monsieur would run the risk, I would suggest that he accompanies me to the office of this man Schwann."
"Well, Bob, what is the matter? You look disturbed. Come in, and take a glass of wine. And Schwann, join us." An hour later, the Square of Saint Amé was bright with lights, to the great joy of the peasants, who uttered many ohs! and ahs! as they entered the shed. Bobichel stood at the door. "Come in, gentlemen and ladies, come in!" And then he continued his shouts. "Wonderful Spectacle.
This the belief of Schwann, although he also regarded the other parts of the cell as of importance. An amoeba. This conception, however, was quite temporary. It was much as if our hypothetical supramundane observer looked upon the clothes of his newly discovered human being as forming the essential part of his nature. It was soon evident that this position could not be maintained.
