Noah Webster's 1828 American Dictionary of the English Language is regarded by many as the finest English
dictionary ever published. The dictionary is available in many forms. I made the content available here for my own purposes,
out of personal admiration for this particular dictionary.
AURE'LIA, n. [from aurum, or aur, gold, from its color. See Chrysalis.] In natural history, the nymph or chrysalis of an insect; or the form of an animal, like a worm or maggot, covered with a hardish pellicle, and in a state of seeming insensibility. From this state, it changes to a moth, butterfly or other winged insect.
