 their customs, habits, dress, and character, were treated of in 

 detail, with stirring accounts of a hunt for polar bears and the 

 results of the chase, encounters with huge icebergs, and the ter-

 resolution of thanks to the Committee on the Public Lecture 

 Course was then proposed and passed.
