Narrative:

On climb out, I noticed a 'smell' and then shortly afterward, the flight attendants (both front an back) called to notify us of a 'mist and smell' in the cabin. We continued the departure (logan 2) and accomplished the hard card procedure. Once oxygen masks on and communications established, I flew the aircraft and coordinated with ATC while the captain ran the normal checklists and coordinated with the flight attendants. We declared an emergency and requested an immediate return to bos. Descent and vectors to runway 27. Captain saw the runway first and proceeded to land aircraft normally. We were met by emergency equipment and determined we could taxi back. We did not take another flight that evening. Note: we had flown another aircraft 3 legs earlier then given a ship change. This was our first leg on another plane. I spoke to maintenance on the next morning and they found only a light fixture at seat row xyz to be burned. Packs, air conditioning and recirculation fans all were normal.
