The nearer therefore those approximate the closer will this mode approach the truth. But, now take and Extreme case ... suppose you had continued your trials ... you would have had the current stronger with and against you, consequently you would have completed the mile down in less time and the one up in a longer period ..." and then he calculates the average speeds, and ends that "you may in case of further conversation entrap your opponent by suggesting a case similar to the above ...", the next letter hopes he has recovered from his Party and tells him that he will send the tools he has ordered on to him at "Falmouth.

EXPERIMENTS ON HORSE POWER
Lieutenant Richard Bastard entered the Royal Navy in July 1798 and saw a lot of action in his career, including the Battles of Trafalgar Rochefort and Copenhagen. He commanded the Wood Paddle Steamer 'Flamer' in 1832 and was on half pay from 1834.
There were several ships of the Royal Navy named Firebrand so the letter probably refers to a ship.
