230 NATURAL HISTORY IN ANECDOTE. 



large arm-chair taken out of a French vessel, and covered 

 with blue satin damask, I sat prepared for my enemies, whom 

 I dreaded much more than the lightning, which was flashing 

 across the iron bars laid upon the floor. I felt that the silk 

 of my place of refuge was some sort of protection against 

 this; but my own arm could alone save me from my four-
