Measurements by Joel A. Foner 10/97-1/98

Notes:

  • Samples were weighed using an Ohaus beam balance (0.01 gm accuracy)
  • Balsa weights weights were calculated based on the listed density (lb / cu ft)
  • (6 lb / cu ft = 1.575 gm / cu in, 4 lb / cu ft = 1.05 gm / cu in)
  • *** Micafilm requires an adhesive, which is not included in these measurements
