The jury in the case of Margaret Garrity, who was tried at Newark for the murder of a man named Drum, who seduced her under a promise of marriage, and afterwards deserted her for another, rendered a verdict of not guilty, on the ground of insanity, on the 13th ult. This disgraceful proceeding had precedents in New Jersey, and it appears to have excited but little of the indignation which it deserved. Margaret Garrity murdered her paramour under extraordinary circumstances, which, doubtless, would have had proper weight with the pardoning power. It is evidently absurd to say, that she, more than any murderess, was insane, and the jury were altogether unjustifiable in rendering a verdict which is unsupported by evidence; and of an assumption of the authority of the Governor of the State, in setting at liberty a criminal for whose conduct there appeared to be merely some sort of extenuation or excuse in the conduct of her victim. It would be as well to have no juries as juries so ignorant or reckless of their obligations. A general council of the once grand confederacy of the Five Nations of Indians, the Mohawks, Onondagas, Oneidas, Cayugas, Senecas, and Tuscaroras--was held at Tonawanda on Friday, September 19th, to celebrate the funeral rites of their last Grand Sachem, John Blacksmith, deceased, and of electing a Grand Sachem in his place, electing Chiefs, &c. Ely S. Parker (Do-ne-ha-ga-wa), was proclaimed Grand Sachem of the Six Nations. He was invested with the silver medal presented by Washington to the celebrated war-chief Red Jacket, and worn by him until his death. The new Canadian Ministry, so far as formed, is as follows: Inspector-General, Mr. Hincks; President of the Council, Dr. Rolph; Postmaster-General, Malcolm Cameron; Commissioner of Crown Lands, William Morris; Attorney-General for Canada West, W. B. Richards; Attorney-General for Canada East, Mr. Drummond; Provincial Secretary, Mr. Morin. Three appointments are yet to be made. The government will be eminently liberal.
