[16] For two letters written by my father relating to Dr. Franklin and Mr. Burke see [appendix] No. 4.

About three years before the dissolution of my connection with Lord Shelburne, Dr. Fothergill, with whom I had always lived on terms of much intimacy, having observed, as he said, that many of my experiments had not been carried to their proper extent on account of the expence that would have attended them, proposed to me a subscription from himself and some of his friends, to supply me with whatever sums I should want for that purpose, and named a hundred pounds per annum. This large subscription I declined, lest the discovery of it (by the use that I should, of course, make of it) should give umbrage to Lord Shelburne, but I consented to accept of 40 £. per annum, which from that time he regularly paid me, from the contribution of himself, Sir Theodore Jansen, Mr. Constable, and Sir George Saville.

On my leaving Lord Shelburne, which was attended with the loss of one half of my income, Dr. Fothergill proposed an enlargement of my allowance for my experiments, and likewise for my maintenance, without being under the necessity of giving my time to pupils, which I must otherwise have done. And, considering the generosity with which this voluntary offer was made by persons who could well afford it, and who thought me qualified to serve the interests of science, I thought it right to accept of it; and I preferred it to any pension from the court, offers of which were more than once made by persons who thought they could have procured one for me.

As it was my wish to do what might be in my power to shew my gratitude to my friends and benefactors that suggested the idea of writing these Memoirs, I shall subjoin a list of their names. Some of the subscriptions were made with a view to defray the expence of my experiments only; but the greater part of the subscribers were persons who were equally friends to my theological studies.

The persons who made me this regular annual allowance were Dr. Watson and his son, Mr. Wedgwood, Mr. Moseley, Mr. S. Salte, Mr. Jeffries, Mr. Radcliffe, Mr. Remington, Mr. Strutt of Derby, Mr. Shore, Mr. Reynolds of Paxton, Messrs. Galton, father and son, and the Rev. Mr. Simpson.

Besides the persons whose names appear in this list, as regular subscribers, there were other persons who, without chusing to be known as such, contributed no less to my support, and some considerably more.

My chief benefactress was Mrs. Rayner, and next to her Dr. Heberden, equally distinguished for his love of religious truth, and his zeal to promote science. Such also is the character of Mr. Tayleur of Shrewsbury, who has at different times remitted me considerable sums, chiefly to defray the expences incurred by my theological inquiries and publications.

Mr. Parker of Fleet street very generously supplied me with every instrument that I wanted in glass, particularly a capital burning lens,[17] sixteen inches in diameter. All his benefactions in this way would have amounted to a considerable sum. Mr. Wedgwood also, besides his annual benefaction, supplied me with every thing that I wanted made of pottery, such as retorts, tubes, &c. which the account of my experiments will shew to have been of great use to me.

[17] Though his sight was not much worse than before during the last ten years of his life it had been much injured by his experiments with the burning Lens of which he made much use in summer time.

On my removal to Birmingham commenced my intimacy with Mr. William Russell, whose public spirit, and zeal in every good cause, can hardly be exceeded. My obligations to him were various and constant, so as not to be estimated by sums of money. At his proposal I doubt not, some of the heads of the congregation made me a present of two hundred pounds, to assist me in my theological publications.
