There has been no successful street revolution in Paris since the days of the Commune, but the terrible under-strata ever and anon break through the thin upper crust of society with some such outburst as that of the dynamite explosions of 1892 in the Boulevard Saint-Germain, in the caserne Lobau, and in the Rue de Clichy. On this occasion, the Paris _Matin_ published the result of the official researches as to the locality of the various groups of anarchists in the city, from which it appeared that they were to be found in associations of greater or lesser numbers in the quartiers of the Bourse, of the Temple, of the Panthéon, of the fashionable Champs-Élysées, among the _valets de chambre_, the cooks, and the coachmen, and in the fourth, ninth, tenth, eleventh, twelfth, thirteenth, fifteenth, eighteenth, and nineteenth arrondissements. In the quartiers of the Louvre, of the Luxembourg, and in the seventh, sixteenth, and seventeenth arrondissements, no organized groups existed. Their titles varied: _L'Avant-garde cosmopolite_, _Le Réveil du quinzième_ (arrondissement), _La Bibliothèque socialiste_, _La Jeunesse anarchiste du vingtième_ (arrondissement), _La Jeunesse révolutionnaire_ and _La Ligue des antipatriotes_; their publications ranged from _Le drapeau rouge_ [the red flag] to _La Révolte_ and Henri Rocheforte's _Intransigeant_. The arrest of the chief dynamiter, Ravachol, was effected through the intelligence of a waiter named Lhérot in the restaurant Véry, on the Boulevard Magenta, of which we give a view, on Victor Hugo's authority that it is always interesting to look at a wall behind which we think something is happening.
