Highness is pleased to hope that he will of his own free will

may bring honour upon himself, and deserve the further favour of the
Prince, his master, who thus confides in his zeal and discretion.

is hereby bestowed upon the said Vice-Capellmeister by his Serene
Highness.

the officers' table, or half a gulden a day in lieu thereof.
