been admitted as a partner and their warehouse and offices at this time were located at Nos. 127 and 129 William street, where a business of enormous proportions, which includes the manufacture of thirty-three inks and other products, is still carried on at the present day under the name and style of "Thaddeus Davids, Co." The old "Davids' Steel Pen Ink" continues to be manufactured from the original formula and is the only tanno-gallate of iron ink they make, WITHOUT "added" color. The Paris house of "Antoine" as manufacturers of writing inks dates from 1840. They are best known as the makers of the French copying ink, of a violet- black color, made from logwood, which was first put on the market in 1853 under the name of Encres Japonaise. In 1860 an agency was established in New York City. They make a large variety of writing inks but do not offer for sale a tanno-gallate of iron ink without "added" color. "Carter's" inks came into notoriety in 1861, by the introduction of a "combined writing and copying ink," of the gall and iron type and included "added " color. It was the first innovation of this character. At the end of the Civil War, John W. Carter of Boston, who had been an officer of the regular army, purchased an interest in the business, associating with himself Mr. J. P. Dinsmore of New York, the firm being known as Carter, Dinsmore & Co., Boston, Mass. In 1895 Mr. Carter died and Mr. Dinsmore retired from the business. The firm was then incorporated under the style of "The Carter's Ink Co." They do an immense business and make all kinds of ink. Of the logwoods, "Raven Black" is best known. When the state of Massachusetts in 1894 decided that recording officers must use a "gall" ink made after an official formula, they competed with other manufacturers for the privilege of supplying such an ink and won it. They do not offer for sale, however, "gall" ink WITHOUT added color. Their laboratories are magnificently equipped; the writer has had the pleasure of collaborating with several of their expert chemists. The "Fabers," who date back to the year 1761, are known all over the world as lead pencil makers. They also manufacture many inks and have done so since 1881, when they built now factories at Noisy-le-Sac, near Paris. Blue-black and violet-black writing and copying inks of the class made by the "Antoines" are the principal kinds. They do not offer for sale, tanno-gallate of iron ink without "added" color. A branch house in New York City has remained since 1843. "Stafford's" violet combined writing and copying ink was first placed on the New York market in 1869, though it was in 1858 that Mr. S. S. Stafford, the founder of the house, began the manufacture of inks, which he has continued to do to the present day. His chemical writing fluids are very popular, but he does not make a tanno-gallate of iron ink without "added" color, for the trade.
