The day on which the undergraduate of University College received his first lot of printed copies from the Worthing printers is unknown; but it cannot have preceded by many days the appearance in the _Oxford Herald_ (9th February, 1811,) of this advertisement:--'Speedily will be published, to be had of the Booksellers of London and Oxford, _The Necessity of Atheism_. "Quod clarâ et perspicuâ demonstratione careat pro vero habere, mens omnino nequit humana."--_Bacon de Augment. Scient._' Probably the appearance of this advertisement in the Oxford newspaper followed closely upon the arrival at Shelley's rooms in University College of the first lot of printed copies from Worthing. Anyhow, the authorities of the University were advertised, so early as the 9th of February, that a work, to demonstrate the necessity of atheism, would be speedily offered for sale within their jurisdiction. Inserted in a newspaper, read by many members of the University, this advertisement came quickly under the eyes of the Vice-Chancellor and Proctors of the University, the Heads of Houses, and all other persons especially concerned in the maintenance of academic discipline at the seat of learning. There was gossip in the common-rooms. Sitting over their port, Doctors of Divinity and Masters of Arts exchanged sentiments respecting the audacious announcement. The proctors took counsel with their pro-proctors, and the acutest and most discreet of 'the bull-dogs' was ordered to keep a sharp look-out for the first copy of the atrocious publication that should be offered for sale in any bookseller's window. Of course it was the opinion of the authorities that Mr. Munday, the proprietor of the _Oxford Herald_, knew the atheist's real name; at least could say what induced him to put such a staggering advertisement in his paper. It cannot be questioned that Mr. Munday's shop, the office of the _Oxford Herald_, was watched day and night by persons who were instructed to take note of all individuals visiting the printer's premises. Doubtless, also, the people at the Post Office were affected by the measures, taken by the academic authorities for the discovery of the person or persons, who should venture to sell atheistical literature in the City of the Church. The Vice-Chancellor and Proctors have good and sufficient means of observing what is done at Oxford in this present year of grace, and had even better means of observation seventy years since.
