• unspecified sextet: participating ensemble

The Vergnügungsanzeiger [daily entertainment almanac] of Mercy’s Anzeiger 21/3/1857 announced that ‘Today Saturday:... Platteis: Sext [Sextet].’ No further details of this event were given by this source. The venue identified ‘Platteis’ may have referred to the public hall and rooms in the building of that name on the corner of St Wenceslas Square, or (more likely given the ensemble-nature of this event), to the ‘Platteis Café-salon located in that same building.
