Forty Centuries of Ink / Or, A chronological narrative concerning ink and its backgrounds, introducing incidental observations and deductions, parallels of time and color phenomena, bibliography, chemistry, poetical effusions, citations, anecdotes and curiosa together with some evidence respecting the evanescent character of most inks of to-day and an epitome of chemico-legal ink.

"The volumes of copies of the old records of Lexington, made in 1853, have faded until they are quite indistinct.

"Some of the old inks, though retaining their black color have, from the presence of acid in the ink or paper, eaten through the paper as thoroughly as if the writing had been done with a sharp instrument. In part of one old volume of court records, the ink, while not injuring the paper or becoming illegible upon the face of the leaves, has gradually become legible upon the reverse, while the heavy paper has been impervious to the other inks used. * * * * * *

To ascertain what kind of inks were in use by the town clerks, I examined the registration volumes before referred to, and, as before stated, found many poor inks in use. In a few cases blue inks were used, and in two violet, which is, as a rule, if not always, a fugitive color. A number of the returns in these volumes of as recent date as 1875 were almost illegible, and three made in 1888 were nearly as indistinct.

"The more I looked into the subject, the more I became convinced that the whole subject of ink was one upon which the persons using it were comparatively ignorant. Consultation with experts satisfied me that good inks were being injured by improper treatment; that the custom of mixing inks and of adding water to them was unsafe; and that among the inks reported as in use upon the records there were many manufactured for commercial uses which should not be used upon records, and which the manufacturers would say were not intended for record inks. I therefore sent to the manufacturers of the inks reported as in use by the recording officers, and to some others, the following letter and inquiries:

" 'The fading of much of the ink used in records of comparatively recent date, while as a rule the records of two hundred years ago are as legible as when written, establishes the fact that for permanent qualities much of the modern ink is inferior to the ancient, and that inks are used that are unfit for making a record which should stand for all time.

" 'I am led to believe that most ink in manufacturers make inks which are good for commercial and other uses where there is no desire for a permanent record, but which they would not recommend for use where the important object was the permanency of the record. One of the dangers to which our records are exposed can be obviated by the use of proper inks; and I desire to obtain the opinion of the leading manufacturers on the subject, that I may advise the recording officers of the State what are, and what are not, safe inks to use for records.

" 'I shall esteem it a favor, therefore, if you will answer the enclosed questions, and return them at your convenience. Your reply will be treated as confidential as far as names are concerned, except in the answer to question No. 5, and that will not be printed if you so request. Any general opinion which will aid the recording officers in their selection of ink or paper will be welcomed.

" '1. Do you consider it safe to use for a permanent record aniline inks?

" '2. Do you consider it safe to use for a record logwood inks?

" '3. Do your consider nut-gall and iron inks absolutely safe for a permanent record?
