"How to make a brazen or stone head, in the midst of a great field or garden, so artificial and natural, that though a man speak never so softly and even whispers into the ear thereof, it will presently open its mouth, and resolve the question in French, Latin, Welsh, Irish, or English, in good terms uttering it out of his mouth, and then shut it until the next question be asked." No doubt the Marquis had in mind the history of the renowned Brazen Head attributed to Friar Bacon. The authors of the works on mechanical subjects published down to the 17th century, did not disdain to describe the way to manufacture automatic men, animals, and birds, with suitable joints, springs, weights, and bellows; and therefore, the Marquis did really no more than express the character of the times, without lowering his own superior intelligence. He was seeking the patronage of royalty, parliament, and the public, and if he offered occasionally such trifles as commanded the attention of the multitude, he never in the whole course of his chequered life lost sight of his more important occupations, the conceptions of a mind far in advance of that dismal and dark period. At the same time, that his age neglected to uphold applied science, and pertinaciously opposed whatever appeared to savour of innovation on time-honoured manufactures and trades, we cannot overlook the anomalous fact that it gave birth to Shakspeare, Bacon, and Milton; Sir Thomas Brown, Wallis, Hook, Newton, and Boyle, together with a brilliant constellation of luminaries who adorned every department of our general literature. Science alone stagnated, and the construction of public works was chiefly conducted by foreign aid. The establishment of the Royal Society in 1660, however, gave promise of that improvement which has steadily gone on year by year to the present day.
