These arachnides remain tranquil, the feet extended, on 
vegetables ; they form no web, but simply throw out some

The second feet, and then the first, are the longest of all. The

the middle, which is round, white, and allows the eggs to ap-

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

denomination reminds naturalists of one of our most zealous 
philosophers, whom I have already recommended to their 
esteem, as my preserver, in the storm of the revolution, is one
