on 26 December 1858, The New Adelphi was opened and was considered an improvement on the cramped circumstances of the original, which had been described as a "hasty conversion from a tavern hall, permanently kept in its provisional state". The new theatre could seat 1,500 people, with standing room for another 500. The interior was lighted by a Stroud's Patent Sun Lamp, a brilliant array of gas mantles passed through a chandelier of cut-glass. In the mid-19th century, John Lawrence Toole established his comedic reputation at the Adelphi. Also in the mid-19th century, the Adelphi hosted a number of French operettas, including La belle Hélène. In 1867, however, the Adelphi gave English comic opera a boost by hosting the first public performance of Arthur Sullivan's first opera, Cox and Box. The building was renovated in 1879 and again in 1887 when the house next door, along with The Hampshire Hog in The Strand and the Nell Gwynne Tavern in Bull Inn Court, were bought by the Gattis in order to enlarge the theatre. They also built a new enlarged facade and part of this can still be seen today above the Crystal Rooms next door to the present Adelphi Theatre. An actor who performed regularly at the Adelphi in the latter half of the 19th century, William Terriss, was stabbed to death during the run of 'Secret Service' on 16 December 1897 whilst entering the Theatre by the royal entrance in Maiden Lane which he used as a private entrance. This is now recorded on a plaque on the wall by the stage door. Outside a neighbouring pub, a sign says that the killer was one of the theatre's stage hands, but Richard Archer Prince committed the murder. It has been said that Terriss' ghost haunts the theatre. Terriss' daughter was Ellaline Terriss, a famous actress, and her husband, actor-manager Seymour Hicks managed the Adelphi for some years at the end of the 19th century. The stage door of the current Adelphi is in Maiden Lane but back then it was in Bull Inn Court. William Terriss would later have a Theatre named after him, the Terriss Theatre in Rotherhithe, later known as the Rotherhithe Hippodrome. The adjacent, numbers 409 and 410 Strand, were built in 1886–87 by the Gatti Brothers as the Adelphi Restaurant. The frontage remains essentially the same, but with plate glass windows, and, like the theatre,
