 that of Tilia Americana, and used for similar purposes.

 Keys, rare ; in the Bahamas, St. Domingo, Cuba, Porto Eico, etc. 



A low, gnarled tree, not exceeding, within the limits of the United States, 8 meters in height, with a trunk 

 sometimes 0.30 meter in diameter. 



Wood exceedingly heavy, very hard, strong, brittle, close-grained, compact, difficult to work, splitting irregularly, 

 containing many evenly-distributed resinous ducts; medullary rays numerous, obscure; color, rich yellow-brown, 

 varying in older specimens to almost black, the sap-wood light yellow ; specific gravity, 1.1432 ; ash, 0.82 ; used in 

 turnery and for the sheaves of ships' blocks, for which it is preferred to other woods. 



Lignum GuaiacL Guaiacum wood, the heart of this and the allied G. officinale, Linnaeus, formerly largely used in 

 the treatment of syphilis, is now only retained in the Materia Medica as an ingredient in the compound deeoctioii of 

 sarsaparilla. 



Guaiac, the resinous gum obtained from these species, is a stimulating diaphoretic and alterative, or in large doses 

 cathartic, and is still employed in cases of chronic rheumatism, gout, etc. (Fliickiger & Hanbury, Pharmacographia,
