These lines you receive through Klindworth. Enclosed is the
letter to the maison Erard, which is represented in London by M.
Bruzot. If Erard himself should be there, pay him a visit at
once, but I doubt whether he is sufficiently recovered to occupy
himself with pianoforte and harp matters. A few months ago my
children wrote to me from Paris that Erard was very ill, and,
after fruitless trials of baths and medicines, had been taken to
a private hospital.

I have not neglected your passport affair, and have induced the
Grand Duke and another important person to recommend you
specially in Paris. I hope these transactions will not be without
result.

The changes you have made in the "Faust" overture are excellent,
and the work has decidedly gained by them. I have sent the score
to the Hartels. If you are satisfied with an honorarium of twenty
louis d'or, write to me simply, "Yes," and the full score and
parts will soon be published. To a larger honorarium the Hartels
would not agree, but they will make the edition better and
handsomer than would any one else, and I should therefore advise
you to answer me in the affirmative.

I shall have to work hard for several months to come. The
Cardinal Primate of Hungary has set me the task of composing a
grand mass for the inauguration of the cathedral of Gran. The
ceremony will take place in August at the latest. The Emperor
will be present, and I have undertaken to conduct the mass, etc.,
for which purpose I have to be in Gran (three hours' distance
from Pesth) a month before.
