SPAIN.  The Journal des Debats, referring to the attempt to assassinate the Emperor of Russia says, " It is now proved that the man who attempted to murder the Emperor of Russia is a Russian, and that he belongs to the sect of Socialist levellers. This sect is now very numerous in Russia, and the Government itself has very much favoured its extension by calling to favour Messrs. Milutine, Tcherkoskoi, and other men of similar stamp, and by giving up to them Poland as a field for their experiments. One influential Russian paper expressed the gratification it felt that the assassin was not a Russian, but a Pole. The accused, however, has himself declared that he is a Russian. He speaks the Russian language perfectly, and, according to the lnvalicle Russe, the Emperor, on receiving the deputation from the Senate who came to congratulate him on his escape, said "the most melancholy thing is that the assassin is a Russian." All this, however, has not prevented the ultra-Muscovites from making the attempt at assassination the pretext for exciting the passions of the populace. When it was supposed that the man was a Pole there were some very violent demonstrations against the Poles at the theatres and elsewhere. Now it is proved that the assassin is a Russian, the Gcvernment has appointed a commission to inquire whether he has any accomplices, the desire being to afford proof that he is supported by the Poles. Another most wonderful change has taken place in the weather. Yesterday, during the day, it was peculiarly sultry, but towards evening there came suddenly a very cold wind, accompanied by copious and violent rain. To-day the wind has been very cold, and a great deal of rain has fallen. In fact, from mid-summer the weather has suddenly veered round to mid-winter. Saturday and yesterday were July days. To-day we have come back to December or January. Rain, however, was very much wanted in the country, and farmers were beginning to complain of the drought. The French weather prophets have been a little wrong in their calculations, for they announced fine and steady weather. The Emperor has conferred the title of duke upon Count Colonna, Walewski, President of the Legislative Body. This makes the seventh duke created by the Emperor, viz., the Duke de Malakoff, de Montmorot (son of the Queen Christina of Spain), de Magenta, de Morny, de Montmorency, and now the Duke de Walewski. Two of these dukes are dead, viz., the Dukes de Malakoff and de Montmorot.  An Antwerp paper states that the wife of a shoemaker at Lieme (Belgium) has given birth to five girls, who with the mother are all in perfect heath and proper conformation.  The second volume of the Emperor's work, the " Life of Caesar," is about to be issued from the Imperial printing office. Extraordinary precautions were taken to prevent any portion of the work from obtaining premature publicity. The forms of the type were locked up every night and the key given  in charge to the foreman, M. de Petetin. Only a few copies of this private edition will be sold, it being intended chiefly for presentation by the Emperor.  The Bourse has been in an agitated state to-day, although I believe no actual news has arrived to warrant the unfavourable impression. An influential paper of last evening, however, had an anticipation that hostilities would immediately commence in Germany and Italy, and some of the papers of this morning re-echo the impression, although without facts to justify the opinion.  Explosion on Board the European at Colon.  LIVERPOOL, April 30.  MADRID, APRIL 30 (Evening).
