Query: The mysterious 1755-56 "A New and Complete History of the British Empire in America"
"A New and Complete History of the British Empire in America" was published serially (a total of 44 Numbers) between September 1755 and September 1756, without being completed. In fact, it reportedly stopped mid sentence! The work contains no title pages, which were to be provided upon completion. An advertisment in September 1755 states the work was "composed from the Manuscripts of an eminent Physician, and three other Persons, who, in the Years 1748, 1749, 1750, 1751, 1752, and 1753, travelled through every Province and Island under the British Dominion; together with many of the Spanish, French, and Dutch Settlements..."
Dr. John Mitchell immediately comes to mind as an "eminent Physician", assuming that the 1748-1753 travels pertain only to the "three other persons". Any ideas who those three other persons were?
The advertisements indicate that the work was published by Jon/John Scott on Paternoster Row.
