Henry W. Bates conveys to ARW’s mother news of the death of her son Edward (Herbert Edward), ARW’s younger brother, who reached camp while ARW was away upriver. He had contracted yellow fever; Bates was with him, obtained physician’s care, but after a few days Herbert perished from the “black vomit,” the most lethal form of the disease. Bates reports that Herbert was well looked after to the end.
