Note 3 — Trees and Woods of the Lignum-vitae Family

The maximum density determined by the writer was 1.32 (about 82-1/2 lbs. per cubic foot) for Nicaraguan lignum-vitae. Krais (“Die Hölzer”) gives the range for dry wood of Guaiacum as 1.17 to 1.39, or from 73 to nearly 87 pounds per cubic foot. Other reliable figures of density are 1.248 (Laslett) and 1.33 (Beauverie). Stone (46) gives 89 pounds per cubic foot for Guaiacum sanctum and cites Sargent (40) as authority. This is an error, as the values given by Sargent are 0.9563 to 1.2736, average 1.1432. Boulger (5) uses the same figure as Stone.
