“In order to proceed with the greatest caution in a business of such moment I desired some of my learned friends, and especially Dr Price, to peruse the work before it was published, and the remarks that he made upon it led to a free and friendly discussion of the several subjects of it, which are afterwards published jointly, and it remains a proof of the possibility of discussing subjects mutually considered as of the greatest importance with the most perfect good-temper and without the least diminution of friendship.”

Lord Shelburne’s political enemies were not slow to take advantage of the outcry raised against Priestley by the orthodox and to strike at the patron through the philosopher.

It is obvious, from Priestley’s letters to his friends at about this period, that he was sensible that his relations with Pitt’s Secretary of State had become somewhat strained, and when he received an intimation through Dr Price that Lord Shelburne wished to give him an establishment in Ireland, where he had large property, he interpreted this as signifying that the Minister desired that their connection should be severed. They parted amicably, Lord Shelburne continuing to pay him the promised annuity of £150 until the end of his days, paying it, too, contrary to the insinuation of his enemies, with perfect punctuality. That there was no unfriendly feeling on the part of Lord Shelburne at a separation which seemed to be dictated solely by considerations of political exigency would appear from the circumstance that a few years later he sent a common friend to Priestley, who was then settled in Birmingham, to invite him to resume his old position, accompanying his request with expressions which left no doubt of the value he set upon the companionship. Sensible as Priestley was of Lord Shelburne’s feelings towards him, he was in no mind to return to a situation which experience had shown might be incompatible with independence.

CHAPTER VII

Removes to London—Declines a pension—Renews his acquaintance with Franklin—Goes to Birmingham—Becomes a member of the Lunar Society.

On leaving Calne, Priestley repaired to London. His position was somewhat precarious, as he had practically nothing but his allowance from Lord Shelburne to support him. This, although larger than the stipend he had enjoyed at Leeds, was barely sufficient for his growing family. Friends however were not wanting to come to his assistance. Indeed, during his residence at Calne, some of them observing, as they said, that many of his experiments had not been carried to their proper extent on account of the expense that would have attended them, proposed to supply him with whatever sums he should want for that purpose and named a hundred pounds per annum.

“This large subscription I declined,” he says, “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 forty pounds per annum, which from that time he (Dr Fothergill) regularly paid me from the contribution of himself, Sir Theodore Jansen, Mr Constable and Sir George Savile.”

This sentence is characteristic of Priestley and of much of his autobiography. Probably no man with so many enemies had such troops of friends, and certainly none had so many and such generous benefactors. And the measure of their beneficence was only equalled by that of Priestley’s gratitude and sense of obligation. Indeed, he says the chief object he had in putting together his memoirs was that he thought it right to leave behind him some account of his friends and benefactors, and accordingly we find that the incidents in his career are dwelt upon by him rather with the idea of illustrating his indebtedness to others than as records of his own achievements.

On his removal to London, where he contemplated resuming his profession as a teacher, Dr Fothergill and his co-subscribers considerably increased his allowance for experiments, whilst at the same time other friends were not less zealous that he should have the means to pursue his theological studies and to publish the fruits of his labours.

Indeed, all who could in any way assist seemed to vie with one another in help. Parker, the optician of Fleet Street, supplied him with every instrument that he wanted in glass, and Wedgwood, the potter, sent him innumerable retorts, tubes and other articles of clay. Without such assistance he could not have carried on his experiments, except on a very small scale and under great disadvantages.
