Subsequently he treated this salt, after many applications of it, with sulphuric acid, when he remarked--
I was soon surprized to observe that red vapours rose from it.
An examination of another portion of the salt showed--
that when it was thrown upon hot coals ... it burned exactly like nitre.
So it was a conversion of sodium chloride into sodium nitrate. That this change must have come from the snow with which it had been dissolved, could not be doubted, and he further observed--
Now in the upper regions of the atmosphere ... there may be a redundancy of inflammable air ... and a proportion of dephlogisticated air. In that region there are many electrical appearances, as the aurora borealis, falling stars &c; in the lower parts of it thunder and lightening, and by these means the two kinds of air may be decomposed, and a highly dephlogisticated nitrous acid, as mine always was, produced. This being formed, will of course, attach itself to any snow or hail that may be forming ... confirming in this unexpected manner, the vulgar opinion of nitre being contained in snow.
This seems to be the last communication of this character which came from the Doctor's pen.
He was in despair relative to the academy which had ever been his hope for the College which in his early years in Northumberland he prayed might arise and in which he would be at liberty to particularly impart his Unitarian doctrines.
An interesting item relative to the Academy appeared in the Aurora for April 1st, 1803. It shows that State aid for education was sought in those early days. It is a report, and reads--
A REPORT of the Committee to whom was referred the Petition of Thomas Cooper, on behalf of the Northumberland Academy, praying legislative aid. The report states that Thomas Cooper appeared before the Committee and stated that upward of $4000 had been expended on the building appropriated to that institution. That the debts due thereon amounted in the whole to near $2000. That Dr. Joseph Priestley had the power of disposing of a very valuable library consisting of near 4000 volumes of scarce and well chosen books in various branches of literature and science, to any public seminary of learning in the United States, which library, the said Dr. Priestley was desirous of procuring as a gift to the Northumberland Academy, provided that institution was likely to receive substantial assistance from the legislature, so as to be enabled to fulfil the purposes of its establishment,
That the Trustees would have no occasion to ask of the legislature on behalf of that Academy, a subscription greater than a few individuals had expended, and were still ready and desirous of contributing thereto; and suggest it to your Committee, that if out of the monies due from the County of Northumberland to the State a sufficient sum was granted to exonerate the Academy from debt, no more would be wanted in the future to effect the purposes of that institution, than a sum equal in amount to the value of the library proposed to be furnished by Dr. Priestley; such value to be fixed by a person appointed for the purpose by the legislature.
The Committee was of the opinion that it would be expedient for the legislature to coincide with the suggestion of Thomas Cooper and so recommended to the Legislature. Their report was adopted, 39 to 31. It was strongly advocated by Jesse Moore, Esq., General Mitchell and N. Ferguson from the city. It was opposed by Jacob Alter from Cumberland, who declared that although there were a great many public schools and colleges and places of that kind scattered over the State, he never knew any good they did, except to breed up a set of idle and odious lawyers to plague the people!
At this particular time there still existed confiscated land from the sale of which revenue was derived, and this income it had been agreed upon should be devoted to the erection and support of academies throughout the State. Later this scheme was discontinued. But, Dr. Priestley was not so enthusiastic as formerly. He was occupied with the Church History, three volumes of which were in print, and it was expected that the fourth volume would follow shortly thereafter. However, his health was precarious. He could not eat meats, and lived chiefly on broths and soups, saying,--
The defect is in the stomach and liver, and of no common kind. If I hold out till I have finished what I have now on hand, I shall retire from the scene, satisfied and thankful.
This was written in August, and the Doctor stuck bravely to his literary labors. A few months later he wrote Lindsey,--
I really do not expect to survive you.
Yet, he also entertained the thought that he might,--
assist in the publication of a whole Bible, from the several translations of particular books, smoothing and correcting them where I can.
January of 1804 brought him many interesting, splendid and valuable books from friends in London. He was overjoyed on their arrival. Promptly he gave himself to their perusal because his deafness confined him to home and his extreme weakness forbade any excursions. Then the winter kept him from his laboratory, and his sole occupation was reading and writing. He entertained a variety of plans, proceeding with some but in the midst of these tasks of love--in the very act of correcting proof, he quietly breathed his last! It was Monday, February 6, 1804, that Thomas Cooper, the devoted friend of Priestley, wrote Benjamin Rush:--
Dear Sir:
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 delivered 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
Dr. Barton's request for permission to withdraw it (Eulogium) to be enlarged and published separately was referred for consideration to the next meeting.
