When I wrote the preceding part of these Memoirs I was happy as must have appeared in the course of them, in the prospect of spending the remainder of my life at Birmingham, where I had every advantage for pursuing my studies, both philosophical and theological; but it pleased the sovereign disposer of all things to appoint for me other removals, and the manner in which they were brought about were more painful to me than the removals themselves. I am far, however, from questioning the wisdom or the goodness of the appointments respecting myself or others. To resume the account of my pursuits where the former part of the Memoirs left it, I must observe that, in the prosecution of my _experiments_, I was led to maintain the doctrine of phlogiston against Mr. Lavoisier and other chemists in France, whose opinions were adopted not only by almost all the philosophers of that country, but by those in England and Scotland also. My friends, however, of the lunar society were never satisfied with the Anti-phlogistic doctrine. My experiments and observations on this subject were published in various papers in the Philosophical Transactions. At Birmingham I also published a new edition of my publications on the subject of _air_, and others connected with it, reducing the six volumes to three, which, with his consent, I dedicated to the prince of Wales. In theology I continued my _defences of Unitarianism_, until it appeared to myself and my friends that my antagonists produced nothing to which it was of any consequence to reply. But I did not, as I had proposed, publish any address to the bishops, or to the legislature, on the subject. The former I wrote, but did not publish. I left it, however, in the hands of Mr. Belsham when I came to America, that he might dispose of it as he should think proper. The pains that I took to ascertain the state of early opinions concerning Jesus Christ, and the great misapprehensions I perceived in all the ecclesiastical historians, led me to undertake a _General History of the christian church to the fall of the Western empire_, which accordingly I wrote in two volumes octavo, and dedicated to Mr. Shore. This work I mean to continue. At Birmingham I wrote the _second_ part of my _Letters to a philosophical Unbeliever_, and dedicated the whole to Mr. Tayleur of Shrewsbury, who had afforded me most material assistance in the publication of many of my theological works, without which, the sale being inconsiderable, I should not have been able to publish them at all. Before I left Birmingham I preached a funeral sermon for my friend Dr. Price, and another for Mr. Robinson of Cambridge, who died with us on a visit to preach our annual charity school sermon. I also preached the last annual sermon to the friends of the college at Hackney. All these three sermons were published.
