THE HELMET HORNBILL! 
Is remarkable for having the same prominence of a conical form ; and in the

countri2s with indifference. He is sometimes indeed seen milk-white, and 
this may probably be the effect of the rigorous climates of the north. A 
raven may be reclaimed to almost every purpose to which birds can be con-
