But a long and almost totalinterruption, from very particular business, joined to a desire(perhaps imprudent) of not delaying the publication much beyondthe time that he originally proposed, prevented the Author fromgiving to the subject an undivided attention. He presumes,however, that the facts which he has adduced, will be found, toform no inconsiderable evidence for the truth of his opinionrespecting the future improvement of mankind.
