The peasants slowly raised the injured man, and as they crossed the Square, they beheld a singular scene. Bobichel had Robeccal by the throat, and pressed his knees on his adversary's chest. "Ah! Bobichel," cried Schwann, "is this the time to fight?" Bobichel rose, and seemed to hesitate, then he flung the scoundrel from him, with contempt and loathing.
Such a fibril may have about it a protective covering, which is known as the sheath of Schwann; but the fibril itself is the essential nerve tract; and in many cases, as Remak presently discovered, the sheath is dispensed with, particularly in case of the nerves of the so-called sympathetic system.
That morning the worthy Schwann, whose ancestors had kept the inn known as the Rising Sun for one hundred and fifty years, said that in all his experience he had never been so busy. Three travelers, three guests in February! It was most amazing. And the worthy innkeeper knew that this was not all.
There has been a long discussion as to the next meeting-place. Grex suggested a yacht. To that they all agreed. There is a man named Schwann down in Monaco has a yacht for hire. Mr. Grex knows about it and he has sent the man I spoke of into Monaco this afternoon to hire it. They are all going to embark at ten o'clock to-night. They are going to hold their meeting in the cabin."
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.
Six more strangers might arrive at any moment; but when he was asked who these strangers were, he winked mysteriously, but looked highly pleased. At the hour when this chapter opens, Master Schwann had just witnessed a veritable slaughter in his poultry yard; pots and saucepans were smoking on the fire, and vigorous preparations were made in the kitchen.
Almost at the same time, and, probably, equally guided by his study of yeast, Schwann was engaged in those remarkable investigations into the form and development of the ultimate structural elements of the tissues of animals, which led him to recognize their fundamental identity with the ultimate structural elements of vegetable organisms.
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.
Schwann's researches made it plain that the best field for the study of the animal cell is here, and a host of explorers entered the field. The result of their observations was, in the main, to confirm the claims of Schwann as to the universal prevalence of the cell.
More revolutionary still in its effects was the epoch-making discovery of the protoplasmic cell as the common element of life in the plant and animal world, made by the Germans Schleiden and Schwann . It was this that first bridged over what were held to be the fundamental distinctions of animate nature, and made possible the conception of a vital physical continuity which has since been accepted as an axiom of biological science.
