“In Mr. Hunt’s book, as well as Mr. Horne’s, Mr. Fry’s name is joined with Mr. Archer’s as the originators of the Collodion process.
“Should Mr. Hunt seem to require any corroboration of what I have stated respecting Mr. Fry, I can send you many of Mr. Fry’s notes of invitation, when Mr. A. merely gave him lessons in the application of collodion, and Mr. Brown gave me the correspondence which passed between him and Mr. Fry on the subject at the time Mr. Home’s book was published. I did not send up those papers, for, unless required, it is useless to dwell on old grievances, but I should like such a man as Mr. Hunt to understand how the association of the two names originated.”
As to priority of application, the following letter ought to settle that point:—
“Alma Cottage, Bishop Stortford.
“9th December, 1857.
“Sir,—My hunting has at length proved successful. In the enclosed book you will find notes respecting the paper pulp, albumen, tanno-gelatine, and collodion. You will therein see Mr. Archer’s notes of iod-collodion in 1849. You may wonder that I could not find this note-book before, but the numbers of papers that there are, and the extreme disorder, defy description. My head was in such a deplorable state before I left that I could arrange nothing. Those around me were most anxious to destroy all the papers, and I had great trouble to keep all with Mr. Archer’s handwriting upon them, however dirty and rubbishing they might appear, so they were huddled together, a complete chaos. I look back with the greatest thankfulness that my brain did not completely lose its balance, for I had not a single relative who entered into Mr. Archer’s pursuits, so that they could not possibly assist me.
“Mr. Archer being of so reserved a character, I had to find out where everything was, and my search has been amongst different things. I need not tell you that I hope this dirty enclosure will be taken care of.
“The paper pulp occupied much time; in fact, notes were only made of articles which had been much tried, which might probably be brought into use.—I am, sir, yours faithfully,
“J. Hogg, Esq.
F. G. Archer.”
If the foregoing is not evidence sufficient, I have by me a very good glass positive of Hever Castle, Kent, which was taken in the spring of 1849, and two collodion negatives made by Mr. Archer in the autumn of 1848; and these dates are all vouched for by Mr. Jabez Hogg, who was Mr. Archer’s medical attendant and friend, and knew him long before he began his experiments with collodion—whereas I cannot find a trace even of the suggestion of the application of collodion in the practice of photography either by Gustave Le Gray or J. R. Bingham prior to 1849; while Mr. Archer’s note-book proves that he was not only iodizing collodion at that date, but making experiments with paper pulp and gelatine; so that Mr. Archer was not only the inventor of the collodion process, but was on the track of its destroyer even at that early date. He also published his method of bleaching positives and intensifying negatives with bichloride of mercury.
