DÜSSELDORF.
A musical society, consisting of 500 effective members, flourishing here for some years, has been gradually falling into decline, the management having come into the hands of some amateurs not possessed of sufficient musical knowledge to conduct it. The fragments of this society now consist of a very few lovers of the art; and they have applied to M. Anton Schindler, to undertake the task of restoring it, if possible, to its former eminence.
