 idea or ideas — as, first, ' burr,' a particular kind of 

 joyous flight : then, ' burr,' something as joyous as 

 such flight, and so, joy: and lastly, 'burr,' the actual

 and all alarm has subsided, there is a great clamorous 

 outburst some little way off. It must have some 

 special cause which I cannot divine, but this com-
