 In the practical analysis of turf it is necessary to attend 

 to the physical constitution of the fuel, as, even with the same 

 chemical elements, the heating power, and the proportion of 

 fixed and volatile parts, will vary with the denseness of tex- 

 ture of the fuel. Important differences exist also in the 

 characters of the turf taken at diflferent depths below the 

 surface of a bog. These circumstances require to be care- 

 fully attended to in practice.
