The most common change which bones first undergo is 

 the loss of more or less of their soft and soluble basis. This 

 effect of long interment is readily tested by applying the 

 specimen to the tongue, when the affinity for fluid of the pores 

 of the earthy constituent, after having lost the gelatine, is 

 so great, that the specimen adheres to the tongue like a piece
