Facts and Thoughts about Spiders. 189 



study of the habits of this dusty domestic creature 

 leads us incidentally into the realms of fable and 

 romance. It is remarkable for the extreme length 

 of its legs, and resembles in colour and general ap- 

 pearance a crane fly, but is double the size of that 

 insect. It has a singular method of protecting

 Pholcus, in spite of its size, is a weak creature, 

 possessing little venom to despatch its prey with,

 greatly excites other spiders in the vicinity, and 

 presently they are seen quitting their webs and

 captor is driven off, and then the strongest or most 

 daring spider carries away the fly. But where a
