 Cobra, and sundry other species of serpents lie 

 in ambush ready to inflict a bite which will almost 

 instantly paralyse them ; or, if they be non-

 are done to death on every available occasion. It 

 is easy to learn to recognise these and other harm-

 fur on the back is thick and rather coarse. It is 

 slaty at the base ; some of the hairs are tipped with 

 black, and others brown, giving the animal a 

 speckled appearance. Under parts are slaty and
