While the philosopher was pondering thus, he felt a continued pulling at his coat-tails. As his wife was in the habit of giving him a gentle pull when he was walking next her absorbed in thought and they met some acquaintance, he took no further notice of it, but took off his hat, and bowing politely towards the railing of the bridge, said "Good-evening."

"These common and original elements in the mimic expression of human beings and higher animals might, if rightly understood, even open out new vistas into the great mystery of life." Another pull. Raschke mechanically took off his hat. Another pull. "Thank you, dear Aurelia, I did bow." As he spoke, the thought crossed his mind that his wife would not pull at his coat so low down. It was not she, but his little daughter Bertha who was pulling; for she often walked gravely next him, and like her mother, pulled at the bell for bows. "That will do, my dear," said he, as Bertha continued to snatch and pull at his coat-tails. "Come here, you little rogue!" and he absently put his hand behind him to seize the little tease. He seized hold of something round and shaggy; he felt sharp teeth on his fingers, and turned with a start. There he saw in the lamplight a reddish monster with a big head, shaggy hair, and a little tassel that fell back into its hind legs in lieu of a tail. His wife and daughter were horribly transformed; and he gazed in surprise on this indistinct creature which seated itself before him, and glared at him in silence.

"A strange adventure!" exclaimed Raschke. "What are you, unknown creature? Presumably a dog. Away with you!" The animal retreated a few steps. Raschke continued his meditations: "If we trace back the expression and gestures of the affections to their original forms in this manner, one of the most active laws would certainly prove to be the endeavor to attract or repel the extraneous. It would be instructive to distinguish, by means of these involuntary movements of men and animals, what is essential and what conventional. Away, dog! Do me a favor and go home. What does he want with me? Evidently he belongs to Werner's domain. The poor creature will assuredly lose itself in the town under the dominion of an idée fixe."

Meantime Speihahn's attacks were becoming more violent; and now he was marching in a quite unnatural and purely conventional manner on his hind legs, while his fore paws were leaning against the professor's back, and his teeth were actually biting into the coat.

A belated shoemaker's boy stood still and beat his leathern apron. "Is not the master ashamed to let his poor apprentice push him along like that?" In truth, the dog behind the man looked like a dwarf pushing a giant along the ice.

Raschke's interest in the dog's thoughts increased. He stood still near a lantern, examined and felt his coat. This coat had developed a velvet collar and very long sleeves, advantages that the philosopher had never yet remarked in his greatcoat. Now the matter became clear to him: absorbed in thought, he had chosen a wrong coat, and the worthy dog insisted on saving his master's garment, and making the thief aware that there was something wrong. Raschke was so pleased with this sagacity that he turned round, addressed some kind words to Speihahn, and made an attempt to stroke his shaggy hair. The dog again snapped at his hand. "You are quite right to be angry with me," replied Raschke; "I will prove to you that I acknowledge my fault." He took off the coat and hung it over his arm. "Yes, it is much heavier than my own." He walked on cheerfully in his thin coat, and observed with satisfaction that the dog abandoned the attacks on his back. But instead, Speihahn sprang upon his side, and again bit at the coat and the hand, and growled unpleasantly.

The professor got angry with the dog, and when he came to a bench on the promenade he laid down the coat, intending to face the dog seriously and drive him home. In this manner he got rid of the dog, but also of the coat. For Speihahn sprang upon the bench with a mighty bound, placed himself astride the coat, and met the professor, who tried to drive him away, with hideous growling and snarling.

"It is Werner's coat," said the professor, "and it is Werner's dog: it would be wrong to beat the poor creature because it is becoming violent in its fidelity, and it would be wrong to leave the dog and the coat." So he remained standing before the dog and speaking kindly to him: but Speihahn no longer took any notice of the professor; he turned against the coat itself, which he scratched, rummaged, and bit. Raschke saw that the coat could not long endure such rage. "He is frantic or mad," said he suspiciously. "I shall have to use force against you after all, poor creature;" and he considered whether he should also jump upon the seat and push the mad creature by a violent kick into the water, or whether it would be better to open the inevitable attack from below. He resolved on the latter course, and looked round to see whether he could anywhere discover a stone or stick to throw at the raging beast. As he looked, he observed the trees and the dark sky above him, and the place seemed quite unfamiliar. "Has magic been at work here?" he exclaimed, with amusement. He turned politely to a solitary wanderer who was passing that way: "Would you kindly tell me in what part of the town we are? And could you perhaps lend me your stick for a moment?"

"Indeed," angrily replied the person addressed, "those are very suspicious questions. I want my stick myself at night. Who are you, sir?" The stranger approached the professor menacingly.

"I am peaceable," replied Raschke, "and by no means inclined to violent attacks. A quarrel has arisen between me and the animal on this seat for the possession of a coat, and I should be much obliged to you if you would drive the dog away from the coat. But I beg you not to hurt the animal any more than is absolutely necessary."
