150 THE BOOK OF A NATURALIST 



a case cannot, I think, be safely set down to fascina- 

 tion, nor to anything more out of the common than 

 curiosity, and, as in the case of the volatile, sprightly 

 fly and terrestrial spider, to the illusion produced 

 in the victim's mind that the suspicious-looking
