The great common error of general historians, ancient and modern, (with a very few exceptions among the moderns,) has been, that they have given to the world little else than narrations and descriptions of wars and treaties, of governmental changes and political events, omitting to record the often far more important facts in the history of literature, science, and the arts of utility, by which the progress of civilization and the development of the human race in its higher capacities have been effected or aided. The great "Instaurator of the Sciences" was the first to call attention to these omissions and deficiencies in all previous histories, and to indicate the duty of historians to avoid these errors,—setting a good example in that respect, in the specimen, or model work, which he produced as a pattern,—his history of the reign of Henry the Seventh. Since his time, many special histories of inventions and of the arts of utility have been written; and the numerous cyclopaedists have largely contributed to this object; still, however, leaving many vacancies to be filled in this department of human knowledge, of which the one before us can not be considered the least worthy of the labor needful for its investigation.
