SOIL FROM MR ANDERSON, BOYSACK". 



This soil was darkish grey when dry, and when moist its 

 colour was very dark. It contained only very small pebbles, 

 some of them pure silicious, and others varying in appearance, 

 and clearly of several different kinds. The subsoil was paler 

 coloured, and the fragments of rock were more angular than in 

 the soil. 



Soluble in Acetic Acid.
