P. S. Since this was written the Bore has been carried 15 feet 

 deeper without any change in the soil. The lignite or fossil wood 

 burns, and emits a smell of coal ; with nitric acid it effervesces and a 

 bright brown smoke arises ; with sulphuric acid this does not take 

 place : on burning it gives out a very strong suffocating smell of 

 sulphur and arsenic.
