A MEMORIAL window is to be placed in the Bristol Royal Infirmary to commemorate the heroic deed of a young surgeon, William Conner, medical officer, who lost his life in a noble and daring effort to save a poor patient who had undergone the operation of tracheotomy while suffering from diphtheria. A false membrane having formed in the throat, and the patient being in imminent danger of his life, young Conner applied his lips to the throat tube, and succeeded in removing the obstruction. The window is in three panels, representing incidents from the parable of the Good Samaritan, and healing the sick, and it will be inscribed, "To the glory of God, and in affectionate remembrance of William Conner, who was born May 7th, 1851, and died July 4th, 1887." A GREAT LOG RAFT.--Not satisfied with the former experiment and catastrophe, the Nova Scotians are putting together another huge log raft, to be floated to New York in July or August of this year. This raft will be 650 feet long, and will have six masts, and a great spread of sail. Confidence seems to be placed in the usual fine weather of July and August; but storms are by no means unknown over the course that the raft will traverse; and should this huge area of floating timber encounter a storm, the chains which will hold the logs together will snap like packing-cord, and leave the crew to shift for their lives in their boats, or by endeavouring to cling to their logs. These experiments, like attempts to swim the rapids of Niagara, should be prevented by some law or regulations, since the common sense of those concerned is conspicuous by its absence. It is quite possible that the raft may be favoured by fine weather, and reach its destination successfully; but it is true, nevertheless, that the enterprise is hare-brained, and undertaken at great risk of life and property.
