The picture which Priestley drew of his life in Birmingham at this period, as given in the autobiographical sketch published after his death, is almost dramatic in its pathos when we bear in mind that it was written almost on the eve of that maniacal outburst of popular passion which eventually drove him from our shores. He said he considered his settlement at Birmingham as the happiest event in his life, as being highly favourable to every object he had in view, philosophical or theological. He thanks God that his prospects are better than they have ever been before, that his own health, and that of his dear wife, is better established, and his hopes as to the disposition and future settlement of his children are satisfactory. He has particular reason to be grateful for the happy temperament of body and mind he owes to his parents, and for the fundamentally good constitution of body to which was due an even cheerfulness of temper which had but few interruptions. Another great subject of thankfulness to a good Providence was his perfect freedom from any embarrassment in his circumstances, for his supplies had been always equal to his wants, and his indifference to an increase of fortune was the means of attaining it. [Illustration: THE PILLAGING OF PRIESTLEY’S HOUSE DURING THE BIRMINGHAM RIOTS] “When,” he says, “I began my experiments I expended on them all the money I could possibly raise, carried on by my ardour in philosophical investigations, and entirely regardless of consequences, except so far as never to contract any debt.... But having succeeded, I was in time more than indemnified for all that I had expended. “Yet frequently, as I have changed my situation, and always for the better, I can truly say that I never wished for any change on my own account. I should have been contented even at Needham if I could have been unmolested and had bare necessaries. This freedom from anxiety was remarkable in my father, and therefore is in a manner hereditary to me; but it has been much increased by reflection, having frequently observed, especially with respect to Christian ministers, how often it has contributed to embitter their lives without being of any use to them. Some attention to the improvement of a man’s circumstances is no doubt right, because no man can tell what occasion he may have for money, especially if he have children, and therefore I do not recommend my example to others. But I am thankful to that good Providence which always took more care of me than ever I took of myself.” This serene contentment is reflected in his correspondence at this period, and we find further evidence of it in the letters of his friends.
