I want to know the answer to the following question:
How many words long was Burke's history of England contracted to be?
All the background I'm provided with is that "On 25 February 1757, Burke signed a contract with Robert Dodsley to write a "history of England from the time of Julius Caesar to the end of the reign of Queen Anne", its length being eighty quarto sheets (640 pages), nearly 400,000 words.". Is that enough to answer the question?
