The following are the particulars of the condemnation of the brig Maria, Slater, alluded to in yesterday's Gazette:

Extract of a letter, received at New-York, dated Amsterdam, May 2.

"The brig Maria and cargo, has been condemned by the will of the Emperor: this case did not pass through any forms of law, but the papers, relating to the vessel and cargo, which were taken from us at Ameland, were sent on to the Emperor, and by him immediately condemned: In the mean time the captain and crew were sent on to Harlingen, Lewarden, Dokkum, Strobos, and Groningen, and in each of those places, confined in a prison, with orders to be kept on bread and water; and had I not become responsible for the payment of more proper food, they must have subsisted on that wretched fare. After considerable exertions, I obtained their release, to come on to Amsterdam, where we were all examined by the police, and but a short time since liberated from the guarantee of the American Consul, who became responsible that we would not leave Amsterdam, until permitted by them. Therefore if this case had been tried by a court of law, I would have been prevented from obtaining the necessary documents, for the captain and crew, on account of their being confined, to invalidate the accusations that might have been made, and to have repaired to Paris, for the purpose, but as this case was decided by the Emperor, to whom the ship's papers were submitted, and as no reasons for the condemnation are assigned to me, and no previous knowledge, communicated to me, that the case would be decided previous to other sequestered property, that has been here upwards of a year, still remained undecided, without the supercargoes or assignees being able to exhibit any statement other than the ship's papers, I could not have supposed that mine would have been so speedily condemned, but that if any thing was done in relation to it, it would have been on general principles, when a complete restoration or condemnation of American sequestered property would have been made, but as this case has been decided by the Emperor, the having such papers, or my being at Paris, would have been of no avail. The reasons of the condemnation are not assigned to me, nor can I even procure a copy of the condemnation, signifying that she is condemned, and such a document is absolutely necessary to meet with no demur in recovering from the underwriters."
