“The second representation of ‘Roberto’ at the Academy last evening, attracted a good audience, which listened attentively to the master-piece of the great Berlin composer.The leading parts were well sustained by the accomplished artists of this company, now so well known and appreciated by the public.The applause was enthusiastic and given with judgment and each performer was fairly dealt with in this respect.”

“‘Robert le Diable’ was given last night to a very good house considering the attractions of the Sanitary Fair, which probably had more effect on the audience here than at any other house.The performance was excellent, and passed off to the entire satisfaction of the house.”
