my lover, so just a request, so I gave her the address she wished; but I
addressed the letter to a city far from you. Is it not, my dear friend,
that you would like well to know the name of the city, so that you could
secure the letter by posts. But you can depend on my word that you will
not know it until you have written me a very long letter begging me very
humbly to indicate the place where the divine letter of the adorable
object of your vows has gone. You might well make this sacrifice for a
girl in whom the Emperor [Joseph II] interests himself, for it is known
that, since your departure from Vienna, it is he who is teaching her
French and music; and apparently he takes the trouble of instructing her
himself, for she often goes to his house to thank him for his kindnesses
to her, but I know not in what way she expresses herself.

"Farewell, my dear friend. Think sometimes of me and believe that I am
your sincere friend."

On the 23rd April 1785, the ambassador Foscarini died, depriving Casanova
of a protector, probably leaving him without much money, and not in the
best of health. He applied for the position of secretary to Count Fabris,
his former friend, whose name had been changed from Tognolo, but without

his friend Maximilian-Joseph, Count Lamberg gave him, among other letters
of recommendation, a letter addressed to Jean-Ferdinand Opiz, Inspector
of Finances and Banks at Czaslau, in which he wrote:

"A celebrated man, M. Casanova, will deliver to you, my dear friend, the
visiting card with which he is charged for Mme. Opiz and yourself.
Knowing this amiable and remarkable man, will mark an epoch in your life,
be polite and friendly to him, 'quod ipsi facies in mei memoriam
