_Saturday, July 19._--A little better to-day. At La Madeleine during part of a Low Mass; my admiration for this building increases greatly; it produces much the same effect as St. Peter's, deceiving the eye by its great proportions. We spent a couple of hours in the boundless galleries of the Louvre. The long gallery contains few pictures that I should much desire to possess: save in the last compartment, and the first room, and none certainly interest me more than that great picture of the battle of Eylau. Thence we went to M. L'Abbé Gaduel, 1. Rue Madame, who took us to the Maison de Campagne of S. Sulpice, at Issy. It is an old royal chateau, much dilapidated, for the good seminarists do not pretend to much comfort in their house; it would seem as if they intended their discipline to serve as a winnowing fan for all light and worldly spirits. They have, however, spacious gardens behind. We were shown a summer house in which Bossuet and Fénélon held a long conference on the subject in dispute between them, and agreed on statements together, which are put up in the room, though the interest of the latter is much gone by in the totally different state of things at present. Eighty young men study philosophy here. We saw and talked some little time with M. Faillon, the Supérieur, a man of learning. M. Galais was out, and we only met him returning on his way from Paris on foot. Coming home we went into the Maison des Carmes, now in repair. M. Gaduel took us into the passage out of which the priests, after stating to the authority the act of their death, were led forward down three steps into the garden, at the bottom of which the assassins fell upon them and murdered them. No spot in Paris touched me more than this. There is what appears to be the marks of a bloody hand in the passage still; but there is no other record of that ruthless deed. The church has nothing remarkable about it: but what devoted heroism on the one side, and what infernal madness on the other, have this house and garden witnessed! How many martyrs here won their crown. Truly it is holy ground, and the blood there shed is yielding a rich harvest of Christian grace in the Church which has sprung up out of its ashes with the strength of a young eagle. In the evening we went to the assemblée générale of S. Vincent de Paul, 2. Rue neuve Notre Dame, under the patronage of the Archbishop of Chalcedoine. The president gave in a long speech an account of their doings; but he was old, had lost his teeth, and dropped his voice, so that we lost very much of it.
