OBJECTS FROM THE ARACHN1DA.

SPIDER'S FOOT. 



THIS favourite object should always have three companions 

 in its box a preparation of Spider's eyes, Spider's jaws,

 of each of these, and also a little of Spiders themselves. 

 W e are so familiar with them, so apt to dislike them in the 

 house and overlook them in the garden, that it will be well
