At Cambridge he gathered no more knowledge than was necessary for his profession, and wasted such hours as should have been given to study in drinking, dicing, and even less reputable pleasures.  Yet repentance was always easy, and he accepted his first curacy, at Newmarket, with a brave heart and a good hopefulness.  Fortunate was the choice of this early cure.  Had he been gently guided at the outset, who knows but he might have lived out his life in respectable obscurity?  But Newmarket then, as now, was a town of jollity and dissipation, and Pureney yielded without persuasion to the pleasures denied his cloth.  There was ever a fire to extinguish at his throat, nor could he veil his wanton eye at the sight of a pretty wench.  Again and again the lust of preaching urged him to repent, yet he slid back upon his past gaiety, until Parson Pureney became a byword.  Dismissed from Newmarket in disgrace, he wandered the country up and down in search of a pulpit, but so infamous became the habit of his life that only in prison could he find an audience fit and responsive.

And, in the nick, the chaplaincy of Newgate fell vacant.  Here was the occasion to temper dissipation with piety, to indulge the twofold ambition of his life.  What mattered it, if within the prison walls he dipped his nose more deeply into the punch-bowl than became a divine?  The rascals would but respect him the more for his prowess, and knit more closely the bond of sympathy.  Besides, after preaching and punch he best loved a penitent, and where in the world could he find so rich a crop of erring souls ripe for repentance as in gaol?  Henceforth he might threaten, bluster, and cajole.  If amiability proved fruitless he would put cruelty to the test, and terrify his victims by a spirited reference to Hell and to that Burning Lake they were so soon to traverse.  At last, thought he, I shall be sure of my effect, and the prospect flattered his vanity.  In truth, he won an immediate and assured success.  Like the common file or cracksman, he fell into the habit of the place, intriguing with all the cleverness of a practised diplomatist, and setting one party against the other that he might in due season decide the trumpery dispute.  The trusted friend of many a distinguished prig and murderer, he so intimately mastered the slang and etiquette of the Jug, that he was appointed arbiter of all those nice questions of honour which agitated the more reputable among the cross-coves.  But these were the diversions of a strenuous mind, and it was in the pulpit or in the closet that the Reverend Thomas Pureney revealed his true talent.
