The rooms were large, airy and full of the odor of tropical fruits and flowers. Beautiful religious pictures hung in several places and good pious books were abundant. The officers' rooms had a large quota of patients. All were brought by sickness to a level with the commonest soldier. We went through the surgical rooms, where operations were wont to be performed. We entered the chapel, a richly adorned and commodious one, where the good sisters so often knelt to pray for the poor invalids. Large, cooling arches spread away before us, and courtyards full of flowers and gushing fountains gave refreshment and rest to the inmates of this vast institution. The good Father showed me immense cellars which contained barrels full of drugs of all kinds. The establishment had three drug stores, all of which were busy supplying the sick with medicines. A proof of the remarkable care taken by the doctors and sisters of the sick in this hospital, may be seen from a report made by a board of investigation which visited Havana in 1880, to inquire into the yellow fever. During the year, 1360 of the army were seized with this disease, 956 outlived it and 411 died, 3 remaining in a doubtful condition. Out of the 174 seized by the disease in the navy, 109 lived and 64 died, 1 remaining in a doubtful state. Out of a total of 1541 invalids 1069 lived and 475 died, 4 remaining in a doubtful condition, thus producing a proportion of 30 to 6 signed by 36 Havana doctors for the army, 4 for the navy, 4 apothecaries, 3 priests and 3 of the military administration.
