Mr. Joseph Priestley is not at present in spirits to write to his friends, and it falls to my lot therefore to acquaint you that Dr. Priestley died this morning about 11 o'clock without the slightest degree of apparent pain. He had for some time previous foreseen his dissolution, but he kept up to the last his habitual composure, cheerfulness and kindness. He would have been 71 the 24th of next month. For about a fortnight there were symptoms of dropsy owing to general debility: about two days before his death, these symptoms disappeared, and a troublesome cough came on perhaps from a translation to the chest.

Yesterday he had strength enough to look over a revise of the Annotations he was publishing on the Old and New Testament, and this morning he dictated in good language some notices which he wished his son Mr. Priestley to add to his unpublished

works. I am sure you will sincerely regret the decease of a man so highly eminent and useful in the literary and philosophical world, and so much presumably your friend.

Yes, the valiant old champion of a lost cause was no more. Two days before his death "he went to his laboratory"—but, finding his weakness too great, with difficulty returned to his room. Loyal to his science to the very end!

To American chemists he appeals strongly because of his persistent efforts in research. His coming to this country aroused a real interest in the science which has not waned in the slightest since his demise.

When the sad news reached the Hall of the American Philosophical Society, Dr. Benjamin Smith Barton was chosen to eulogize Priestley. This notable event took place on January 3rd, 1805. The Aurora reported:

Dr. Benjamin Smith Barton, one of the vice-presidents of the American Philosophical Society, having been previously appointed by the society to deliver an eulogium to the memory of their late associate, Dr. Joseph Priestley, the same was accordingly de

livered in the First Presbyterian Church in this city, on Thursday the 3rd inst. before the society, who went in a body from their hall to the church, preceded by their patron, the governor of the state. Invitations were given on this occasion to the Revd. Clergy of the city; the college of Physicians; the Medical Society; the gentlemen of the Bar, with the students at Law; the trustees and faculty of the University of Pennsylvania, with their students in the Arts and in Medicine; the judges and officers of the federal and state Courts; the foreign ministers and other public characters then in the city; the mayor; aldermen and city councils: the trustees and session of the First Presbyterian Church; the directors of the City Library; the directors and Physicians of the Pennsylvania Hospital, of the Alms House, and of the Dispensary; the proprietor and Director of the Philadelphia Museum; and the contributors towards the Cabinet and Library of the Society. After the conclusion of a very interesting eulogium, the society returned their thanks to the orator, and requested a copy for the purpose of publication.

One's curiosity is quickened on thinking what Barton said in his address. Search in many directions failed to bring forth the Eulogium. It had been ordered to be printed in the Transactions of the Society. This was never done. But there was a minute (seven years later) in the meeting of the Society (Nov. 6, 1812) to the effect that
