Dramatic Feuilleton Making frequent references to the ninety-degree heat, Figaro writes to Mr. Editor of the performances he has attended around town, including two nights at Irving Hall, one night at the Academy of Music, an afternoon show of the frogs at Dodworth Hall, and almost an entire "forenoon" at Barnum's.  Figaro reports that things have mostly gone smoothly at the performing venues this week and also notes that Maretzek has ended his public argument with the <cite>Herald</cite>.  Figaro reviews the "Bateman Concerts" at Iving Hall, discussing Bateman himself, his new prima donna, and his orchestra.  Figaro notes that the re-opening of the Olypmic should be worth commenting on, but claims he has little to say in light of the heat.  He concludes with a list of performances at the other theaters and concert venues around town.
