(527) During the rest of the afternoon all functions operated normally. November 17th. (This memorandum written on the 18th., however, for reasons that will appear below; The events are of the 16th. and 17th.) (16th)At about 10:20 P.M. I looked at the young birds. They seemed the worst normal, but the larger one--the one that had had diarrhoea in the nest and apparently recovered--suddenly gave a harsh scream, spread his wings and dashed about frantically, then subsided with his bill slight ly open and, finally falling off to sleep. That reminded me that the day I had heard a similar scream from the nest before the first youngster was found dead. About 6:30 the morning of the 17th. I looked at the birds. The large one was stretched out on its side gasping with eyes closed, The eyes of the smaller one were slightly dim and not quite so wide open as usual, but it wanted food. The droppings in the nest were few, but all in the vicinity of the smaller bird.(Of course, this proves nothing). Designate the larger bird by L and the smaller by S. L was a dying bird if I ever saw one, struggling and gasping as if to expire within a few moments. I got into touch with Mr. John Brock as soon as I could and took both birds over to his house at his suggestion where Mrs. Brock, with great generosity, put aside everything else, prepared a special custard and exerted her special skill in behalf of the youngsters. Jointly we gave them enemas and removed some very fetid matter from L especially, administered a one few drops of medicinal oil internally and gave each x minute portion of the custard and a drop of water once when they asked for food. L continued to gasp and make efforts to evacuate unsuccessfully. S was rather lively, but not just right, and occasionally gasped and opened his bill for considerable periods. L seemed about to die. Their abdomens were extended and tense. L was in agony and made plaintive sounds. S seemed doomed to follow the same route. It
