From Europe.
--A gentleman in this city has received per the Confederate steamer Nashville, from a friend in London, an interesting letter, from which we have been kindly permitted to make the following extract:‘ "The Trent affair retarded rather than hastened the raising of the blockade of our ports. The measure, I have the best reasons for believing, was agreed upon some weeks ago between England and France--the former power to take the initiative. The settlement of the Trent difficulty on terms so disgraceful to the Lincoln Government, renders it somewhat indelicate for her in view of such a triumph now to do so. I am certain, however, that it will occur soon. All Europe will be united upon the subject"
