In regard to the tunesheet query from Niko Wiegman [151116 MMDigest],
the second title is "Rachel! Quand du Seigneur" from Act IV of the
French opera "La Juive" by Jacques François Fromental Halévy, libretto
by Eugène Scribe.

The third title is "Le songe d'une nuit d'ete: Choeur des
gardes-chasses", composed by Ambroise Thomas; this is "A Midsummer's
Night Dream"

The fourth title is Giacomo Meyerbeer: "Le prophete - Pastorale:
"Pour Berthe, moi je soupire".

For the first title, the composer name looks like Donizetti, in which
case it is maybe from the opera "Caterina Cornaro".
