This popular guide was first published in 1761 and was later translated into German, Dutch, French and Italian. It appeared at a time when Great Britain was codifying its position as the most sophisticated commercial empire in the world. At the time of the eleventh edition stock in the East India Company held an allure comparable to shares in internet start-ups in the mid-1990s. As his lengthy sub-title title suggests, Mortimer was critical of brokers and hostile toward speculators and jobbers. However, his detailed advice offers one of the best accounts of stock trading in the second half of the eightee.
