John Berend, joyner and instrument-maker, lately arrived
from Lisbon, lives on the south-side of Race-street, between
Third-street and Moravian-alley, in a red board house, where
he makes and repairs different sorts of musical instruments,
such as harpsichords, spinnets and clavichords, in the
neatest manner, at reasonable rates.  He has also one new
made harpsichord to sell.
