Bulls and Bears.

Chambers's Encyclopaedia, Volume 2: Beaugency to Cataract, p. 543

Bulls and Bears. In the slang of the stock exchange, a bull is a person who seeks artificially and unduly to raise the price of stock, and speculates on a rise. On the other hand, a bear is one who speculates on a fall; who sells stock for delivery at a future date, in the hope that meanwhile prices will fall, so that he will buy at a lower price what he has sold at the higher price. See STOCK EXCHANGE.
