May 24th. No early morning singing. As I was busy I scarcely saw the thrashers all day, but at about 7:30 P.M. both appeared at the dormitory tree, B going to his accustomed roost and his mate elsewhere--not located. The little thrasher has not improved. May 25th, raining. The little thrasher is weaker, if anything, but very tame and friendly, often answering me with chinks when I talk to her. 4 P.M. I have not seen the adults today. Little G is very weak and is mere skin and bones, and now beginning to refuse even worms. I just noted "the" fly sitting on her head and wonder if this creature carries infection. I have talked with Mr. Brock, and, as a result, have given her a very small portion of the custard used with the young birds of nest No. 5. As she would not eat it, it was put far down her throat with the feeder. 5 P.M. She seems stronger. Her excrement has changed from grey to a rusty brown and is more copious and thicker. She was given another very small portion; after which she kreached for a worm. 6 P.M. She was sitting on the perch (hitherto she has remained on the bottom of the cage) and appears to be looking for a still higher perch. Another small portion was given her. About 7 P.M. she was struggling on the floor of the cage. I held her loosely in my hands and she ceased struggling and lay quiet with eyes closed. Occasionally she would bend her head far back with bill raised beyond the vertical. I placed her on a soft cloth on the floor of a cage and left, as I did not care to see her death-struggle. In a half hour or so I looked in and she was dead. Dr. Reynolds performed an autopsy later in the evening. Subject to his confirmation: all internal organs appeared to be sound,
