contrary to the rules of the establishment to serve less than an entire _livraison_. To ask for half a livraison, he said, was like ordering half a mutton-chop or half a lemonade." The establishment of the Café Littéraire was contemporaneous with the first issue, on a large scale, of three-franc volumes and four-sou _livraisons_, with liberty of the Press, open discussion, and the ascendency of literary men in connection with politics. As a natural consequence of this general intellectual activity, a taste for popular science arose, which the astronomer on the Pont-Neuf, with his long telescope and his interminable orations, was unable to satisfy. The electric cafés instituted at this period were sufficiently curious establishments. A thirsty Parisian entering one of them for the first time in his life, found himself in a place which resembled a buffet more than a café, and in which the most remarkable object was an enormous metal counter. Having swallowed his beverage, he proceeded to place his piece of money on the counter, when, to his astonishment, he received a violent shock in the right arm, which probably caused him to drop the coin as if it were red-hot. "I have had an electric shock!" he would exclaim to some frequenter lounging near him. "Impossible!" would be the reply. "You must have knocked your funny-bone against the edge of the counter." Protesting that he had received a galvanic shock, the victim was assured by the lounger, who had been lying in wait for his joke, that he had simply been electrified by the charms of the young lady behind the counter, just as a theatrical audience is said to be electrified by an actress or _prima donna_. Again, however, on receiving his change the new customer experienced a sharp shock, being the more astonished inasmuch as the _habitués_ present put down and took up their money evidently without feeling the electric current. Then he went away mystified, to return, perhaps, later in the evening with an inexperienced friend, whom, partly from curiosity, partly in a spirit of mischief, he led up to the counter. His friend no sooner touched it than he started back electrified, but he himself found that he could this time touch it with impunity. He had now obviously been admitted amongst the initiated; and when he had gone on drinking and spending enough to entitle him to confidence, the beautiful _demoiselle du comptoir_ condescended to explain to him the entire mystery. At the foot of the metal counter was a piece of strip iron connected with one of the wires of a galvanic battery, the other wire communicating with the counter itself. When any of the initiated touched the counter the presiding goddess stopped the current, which only novices were intended to feel. The whole device was simply employed to amuse customers. The electric counters became very popular, and had rapidly spread all over Paris, when the Government, thinking probably that such practical jokes
