From the map given at the end of this paper, those interested will 

 be able to see exactly from which parts of the Cenlral Provinces these 

 black cobras come ; and I should be grateful if any member interested 

 in geology would inform us whether there is anything in the soil of 

 these places likely to favour the production of this colour.
