I've dug up two local reports of his death and funeral.
...."FUNERAL OF PTE. MORRISON. - On Friday last a funeral took place at Roseneath of quite a pathetic nature. One of the invalided soldiers, named Morrison, lately returned from South Africa, was received into the Hospital Home, Roseneath, maintained by the liberality of the Duke and Duchess of Argyll for the benefit of invalided soldiers. At the express wish of the large hearted patrons of this institution, a specialist was consulted; but it was evident from the very beginning that no reasonable hope could be entertained of the patient's recovery. His once robust constitution was entirely shattered. Yet he was full of confidence himself, and in his brighter moments his eyes used to kindle with martial spirit as he related with spirit and enthusiasm that his regiment had fought 22 battles and marched more than 500 miles, often on half rations, and frequently without shelter at night. Private Morrison spoke very highly of the unremitting care and kindness of Sister Liddell, thanks to whose skilful nursing he lingered longer than had been anticipated. When the end came he faced death as a soldier and as a Christian. He had the consolation of being attended by his own sister in his last moments. On the 27th of February last Sister Liddell wrote of him - "Pte. Morrison died this afternoon at 3.30 P.M. His end was peace."
....The sympathy evoked by his death was quite remarkable. A large number of people from the village attended the funeral, anxious to pay their tribute of respect to the memory of one of her late Majesty's soldiers. The presence of the Duke of Argyll was commented upon as a most graceful act. There were also noticed Captain Williams, Rev. Mr M'Ewan, Mr Maughan, Captain Gray, Captain Ralston, Mr Lewis, Mr Stewart, Mr M'Phee, and several other gentlemen. The procession started from the hospital home at 1 P.M. The coffin was covered with the Union Jack, and was followed by the sister of the deceased as chief mourner, Miss Liddell, and the gentlemen above mentioned. All the patients of the home also turned out to accompany their deceased comrade to his last resting place. They received his remains at the graveyard, and paid them a respectful farewell duty. The funeral service was read by the Rev. T. Delbeke. One of the gentlemen present at the grave was heard to make a remark which seemed to strike the keynote of the general feeling - "I attended the funeral of this soldier because he laid down his life for his country." There was a heavy downpour of rain at the grave, when his Grace considerately went round to the head of the coffin, and held his umbrella over the head of the deceased's sister while the coffin was being lowered into the grave."

The report below is brief, and gets his name and regiment wrong, but it tells us that Edward Morrison was, presumably, Catholic.
...."The funeral of James Morrison, of the Argyll & Sutherland Highlanders, who died on Wednesday in the Convalescent Home, Rosneath, took place on Friday, and was attended by Father Delbeke, Helensburgh. Captain Williams and Sergeant-Major M'Donald, Helensburgh, were also in attendance. The coffin was conveyed in a hearse from the home to the churchyard, covered with the Union Jack, and followed by a large company, including His Grace the Duke of Argyle."
