Remarks. These popular divisions are inserted for

direction, in regard to the language to which he has 
been accustomed. For the same purpose, he should be 
guarded against considering lava as entitled to a place 
among vermes. ‘Though Jarvaare usually called worms, 
they are insects on the transmigratory passage from the 
ege tothe winged state. Therefore the student is to 
consider the caterpillar, the maggot, the web-making 
larva, and all other common animals called worms, ex- 
cepting the angle-worm, as insects.
