These arachnides remain tranquil, the feet extended, on 

 vegetables ; they form no web, but simply throw out some

The Micrommate argelas (Dufour, Ann. des Scienc. Phys. 

 vi. p. 306, xcv. 1 ; Walck. Hist., des Aran. IV. ii.) whose 

 denomination reminds naturalists of one of our most zealous 

 philosophers, whom I have already recommended to their 

 esteem, as ray preserver, in the storm of the revolution, is one
