The news from Petersburg of the 13th of June is, that the last advices received from Mohilew have confirmed the news, that the Empress would return sooner than was at first expected, and that the Emperor, under the name of the Count de Falckenstein, would arrive at the same time, at Petersburg. That the fleet of Cronstadt had been eight or ten days in the road, waiting only for their final instructions to put to sea. It will be separated into three divisions, each of five ships of the line, under the command of the Rear Admirals Barisson, Cruse, and Polibin. Since the departure of a courier, which Mr Harris, the British Envoy, has expedited to his Court, the 26th of last month, a report has been spread, that he has demanded his recall. The ordinance, which the Empress has passed at Czarsko-Zelo, on the 19th of May, to the end to ascertain the rights and duties of her subjects relative to the neutrality, is too remarkable, in the present conjuncture, not to be given entire to the public. The following is the preamble. "The maritime war, subsisting for some time between Great Britain, on the one part, and France and Spain on the other, has begun lately to do equal injury to the commerce and the navigation of our faithful subjects.

They have already been announced to all Europe, by a declaration delivered in the same terms to the three belligerent powers, by which we fix expressly and with precision, the rights and prerogatives of a commercial neutral flag. The one and the other are founded either upon the proper terms of our Treaty of Commerce with the Crown of Great Britain, or upon the evident and immutable principles of the law of nature and nations. But while we require of other nations, for our proper utility the entire and unlimited accomplishment of their duties, we are not less fixed in the intention on our part to observe inviolably, in regard to them, the obligations of the strictest neutrality. Thus it is necessary, that all our subjects should conform themselves vigorously in their maritime commerce, and in the enterprises relative to it, to this our will. In default of which, they will render themselves unworthy of our protection and of our succor. But to the end, that no man may fall
