_Monday, 2nd._--Attended to see Governor White installed in office. The city artillery roared, and the ceremony was made brilliant by the presence of the staff, as well of the regular American army stationed here as of the numerous local corps of the city; of these volunteers, were officers of all arms exceedingly well-appointed; they had also a more military air, and were better set up, than their fellow-soldiers of the North. The French citizen, in fact, acquires a more soldierly appearance, and takes greater pains to fit himself for these holiday doings, than either John Bull or brother Jonathan. A great number of ladies also graced the hall of assembly with their presence, and were, as on all public occasions, privileged persons. "_Place aux dames_" rendered the possibility of one of the masculine gender's approach all but impracticable. Certainly in no country is there such universal and exclusive homage extended to the softer sex: no matter at what expense of his convenience, or circumscription of privilege, man must give way on all occasions where the ladies may have a caprice to indulge in, or any curiosity to gratify. Dined with Colonel D----k, and sat next to a fine old Irishman, General M'L----n, who had passed some of sixty years in Louisiana, yet preserved his brogue and his ruddy complexion as freshly as though the time had been spent on the hills of Wicklow; he had arrived here under the Spanish government when a young man, and spoke of all the changes since as events of yesterday. _Tuesday, 3rd._--A curious scene began this morning at the State House. Mr. Grimes, one of the late candidates for the Senate of the United States, encountering Mons. La Branche, the Speaker of the Louisianian legislature, in the hall of the Senate, according to report, struck him with his whip on account of some unsettled dispute, and in return received a bullet from the Speaker's pistol, which took effect in the breast of the great-coat he wore, but failed to penetrate it. Mr. Grimes, upon this, fired his pistol, loaded with ball and buck-shot, at Mons. La Branche, wounding him slightly in the hand, and leaving one or two of the conscript fathers, standing near, in doubt whether they were shot or no, so disgustingly close was the whiz of the passing lead. Dined with Messrs. T----n, where the affray of the morning was duly discussed; some of the parties present alleging that the quarrel arose from political, others from personal motives. It appeared, however, that Mons. La Branche, after retiring until his hand was dressed, immediately returned to the hall, and resumed his duties as the presiding judge of the highest deliberative assembly of this great State; whilst, within an hour, Mr. Grimes, who is an able advocate in great practice, was pleading a cause on which he was retained in one of the civil courts.
