The sitting magistrates, Major WILDE, and W. HODGSON, Esq., were occupied this (Friday) morning, in disposing of a charge of assault preferred by Mr. SILAS SAUL, solicitor, against Mr. GEORGE FERGUSON, of Houghton Hall.  The parties had appeared before the magistrates, on the subject, on the 16th instant, when it was understood that Mr. FERGUSON had made an ample apology before the bench, and that Mr. SAUL had expressed himself satisfied; but owing to certain expressions of Mr. FERGUSON, which had been reported to Mr. SAUL, that gentleman applied to the bench to have Mr. FERGUSON bound over to the sessions, when he stated it to be his intention to indict him.  From the statements of both parties it appeared that the assault originated in Mr. SILAS SAUL having turned Mr. RICHARD FERGUSON out of his office, when that gentleman had called there in reference to some family trust matters, in which Mr. SAUL was acting for the trustees, and his manner had been what Mr. SAUL considered impertinent and insulting.  Mr GEORGE FERGUSON, the defendant, subsequently called at Mr. SAUL'S house at Millhouse Cottage, to demand an apology on the part of his brother, which not being conceded in writing, as he required, induced him to horsewhip Mr. SAUL, as he was leaving that gentleman's house.  The differences between the statements of the parties were immaterial, and the assault was not denied; but Mr. FERGUSON protested against the Bench entertaining the complaint a second time, when they had adjudicated upon it before.  The Bench overruled this objection, because, in permitting Mr. FERGUSON to apologize in the first instance, and so to satisfy Mr. SAUL, they had not so adjudicated as to preclude their deciding upon the merits, subsequently, if it became necessary; and Mr. HODGSON, of Houghton House, cited a case which fully justified the bench proceeding.  The assault was not denied, not the expression, that "the whip was still as good as new, to horsewhip the complainant if necessary."  The Bench accordingly ordered the defendant to find bail to appear at the sessions, himself in £100, and two sureties in £50 each.  Mr. CHARLES THURNAM, the bookseller, and Mr. JOSEPH HOPE, jun., winemerchant, subsequently entered into the required recognizances for Mr. FERGUSON.
