have entered more largely on this subject, in an "Inquiry of the Literary and Political Character of James I."[51] Periodical papers seem first to have been more generally used by the English, during the civil wars of the usurper Cromwell, to disseminate amongst the people the sentiments of loyalty or rebellion, according as their authors were disposed. _Peter Heylin_, in the preface to his _Cosmography_, mentions, that "the affairs of each town, of war, were better presented to the reader in the _Weekly News-books_." Hence we find some papers, entitled "News from Hull," "Truths from York," "Warranted Tidings from Ireland," &c. We find also, "The Scots' Dove" opposed to "The Parliament Kite," or "The Secret Owl."--Keener animosities produced keener titles: "Heraclitus ridens" found an antagonist in "Democritus ridens," and "The Weekly Discoverer" was shortly met by "The Discoverer stript naked." "Mercuriua Britannicus" was grappled by "Mercurius Mastix, faithfully lashing all Scouts, Mercuries, Posts, Spies, and others." Under all these names papers had appeared, but a "Mercury" was the prevailing title of these "News-books," and the principles of the writer were generally shown by the additional epithet. We find an alarming number of these Mercuries, which, were the story not too long to tell, might excite laughter; they present us with a very curious picture of those singular times. Devoted to political purposes, they soon became a public nuisance by serving as receptacles of party malice, and echoing to the farthest ends of the kingdom the insolent voice of all factions. They set the minds of men more at variance, inflamed their tempers to a greater fierceness, and gave a keener edge to the sharpness of civil discord. Such works will always find adventurers adapted to their scurrilous purposes, who neither want at times either talents, or boldness, or wit, or argument. A vast crowd issued from the press, and are now to be found in private collections. They form a race of authors unknown to most readers of these times: the names of some of their chiefs, however, have reached us, and in the minor chronicle of domestic literature I rank three notable heroes; Marchmont Needham, Sir John Birkenhead, and Sir Roger L'Estrange.
