Later, especially when scientific speculation had made the theistic problem urgent, he was a frequent contributor to the literary monthlies.
The monthly reviews include the Christian Observer (1802-1857), conducted by members of the established church upon evangelical principles, with Zachary Macaulay as the first editor; Monthlies.
Other monthlies are the Indian Magazine (1871); the Irish Monthly (Dublin, 1873); the Gaelic Journal (Dublin, 1882); the African Review (1892) and the Empire Review (1900).
The Monthly Review (1900-1908), edited till 1904 by Henry Newbolt, was for some years a notable addition to the high class literary monthlies.
Shilling monthlies began with Macmillan (1859), the Cornhill (1860), first edited by Thackeray, and Temple Bar (1860).
