The second occasion was in August, 1835, when the British Association made its first visit to Dublin; Dr. Bartholomew Lloyd, then Provost, was the President of the Association, and some of the leading scientific men of England and of the Continent were present. A considerable number of these were accommodated during the meeting with chambers in the College, and had their breakfasts and dinners in the Hall. A great banquet was, moreover, given to the Lord Lieutenant of Ireland (the Earl of Mulgrave), and to about 300 members of the Association, in the Examination Hall. The guests assembled before dinner in the College Library, and His Excellency took the opportunity of conferring the honour of Knighthood upon the Professor of Astronomy, William Rowan Hamilton. This was the first instance in which an Irish Viceroy had so honoured an individual for eminent scientific merit. At the dinner which followed, Professor Whewell of Cambridge remarked in his speech that it was then just one hundred and thirty-six years since a great man in another University knelt down before his Sovereign and rose up Sir Isaac Newton. Among the foreign visitors were De Toqueville, Montalembert, Barclay de Tolly, L. Agassiz, and many others. The general history of Trinity College during the nineteenth century would be incomplete if some reference were not made to a matter which elicited considerable public feeling at the time, but which is now almost forgotten. On the 12th of March, 1858, the Earl of Eglinton, who had been very popular as Viceroy of Ireland on a previous occasion, returned as Lord Lieutenant on a change of Ministry. It was quite a holiday in Dublin. Several hundreds of the students had assembled within the enclosed space in front of the College (which was at that time larger than it is now), and had crowded out into the street, for the purpose of witnessing the procession in its progress up College Green and Dame Street to the Castle. For some time previous to the approach of the Lord Lieutenant, they amused themselves by letting off squibs and crackers, and by throwing orange peel and other similar missiles at the crowd outside, as well as at the police. The Junior Dean, apprehending some ill results if the disposition and temper of the students were misunderstood by the people and by the police, went out amongst them, and begged that they would not resent these demonstrations on the part of the students. No political display was intended by them, and consequently if good humour were preserved on both sides all would pass off quietly. Colonel Browne, who was in command of the police, on two or three occasions went inside the railings to reason with the students; his reception on each occasion was courteous, and he was cheered by the College men. From the period when the Viceregal procession came in sight, there was a suspension of the bombardment from within the College rails. As the Lord Lieutenant passed by, there
