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"
