Sivatifey Coal. 

 Its colour is black. 

 Its luftre 2. Tranfparency o. 



Its fradlure foliated, but fome lamellae being at right an- 

 gles with the other give it a fibrous or ftriated appearance. Fragr 

 ments 2. 



Its hardnefs 5. very brittle. Specific gravity 1,357 by my 

 trials. 



It burns more flowly than the former and cakes. 



240 grains of it treated as the former kinds left 8 grains of 

 yellowilh red afhes ; that is equal 3,33 per cent. 



Of this coal 68 grains were requifite to decompofe 480 grains 

 of nitre. Then 100 grains of it contain 73,53 of carbon, 23,14 

 of a mixture of maltha and afphalt, and 3,33 of alhes. The 

 afphalt feems to predominate.
