Assuredly the saddest congregation that this old Church has ever held! Around the stoves are huddled knots of soldiers, French and German, whose common affliction has changed bitter foes into sympathising friends. These are men whose wounds are comparatively light; and who, poor fellows, for five or six days have not enjoyed the privilege of a bed. They lie in all postures around the fires, trying to sleep,--a difficult task with a broken arm, wrist, or rib, or with severe flesh wounds; and they have no covering of any kind, and only a little straw and the hard flags to rest upon. Passing along the lines of beds are Sisters of Charity, who administer every comfort they can, arrange the patients' beds, smoothe their pillows, and whisper words of solace and consolation. In the stillness of the Christmas night the tones of agony and suffering echo through the Church, which for centuries has resounded at that hour with the grand and solemn music of the Midnight Mass. What a comment on the words of the "_Gloria in Excelsis_," in which these Christians say they believe! "_Et in terra pax hominibus bonæ voluntatis._" Man, I cannot but observe to myself, thou art as much a scandal as a mystery to the reflecting mind! I begin my rounds, visiting first the more urgent cases. To some of the greatest sufferers I give morphia in pills, or else introduce it in solution under the skin, by means of a syringe with a sharp perforated needle affixed. The effect is wonderful. In a few minutes they are out of pain, and fall asleep quietly. In this manner I am compelled to silence those whose groans would disturb the other patients. I now go on in succession, stopping at every bed to satisfy myself as to the condition of its occupant, giving medicines when required, arranging bandages here and there, and soothing with hypnotics those whose wounds prevent their sleeping. This done, I repair to the sacristy, which serves the purpose of a surgery and a waiting-room, and read before the fire for an hour, when I return to the Church to see that all is right, and that the infirmarians are awake and at their posts. As I stand in the Sanctuary and listen, I can hear the heavy tread of the watchers pacing to and fro: nothing else, save the heavy breathing of the sleepers. What a change in less than two hours! The cries of pain are silenced, and the restless day of suffering is succeeded by a night of calm repose;--a pleasant sight for the surgeon, and one which is entirely due to that friend of humanity, so long as rightly administered,--the drug opium. To be prepared, however, for emergencies, I return to my room, and lay out my instruments so as to be ready for an operation if necessary; secondary hemorrhage, and such-like mishaps, being of frequent occurrence.
