A GREAT INVENTION. Story of How Film Was In- vented Told Graphically. In August, 1839, Louis Jacques Maud Daguerre announced to the world the photographic process, which in his honor, because known as "Daguerreotype" the first prac tical process of its kind, and a most remarkable discovery. The dagerre otype, though expensive, became very popular In America, and the predecessors of Ansco Company were he first in this country to manufacture daguerreotype plates which were of metal, coated with quicksilver. The "Calotype" invented by Fox Talbot, an Englishman, soon sup plemented the daguerreotype. This was also known as "Talbotype" and was the first process employing coat ed paper. Later came the collodion process so popularized the making of photographs that by 1858 ama teur photography had become firm ly established. The inconvenlence attending the use of wet plates stimulated the dis covery and adaptation of collodion dry plates, later replaced by gelatine emuision dry plates which, with im provements, are in use today. A demand for a flexible support for the gelatine emulsion, which would supplant the cumbersome dry plate where occasion required, became insistent fairly early Id the evolution of photography. The So clete Francaise, In 1880, offered a prize for a Successful solution of this problem, but when the compe tition closed on December 31st or tiie same year, the prize remained nnawarded and the task appeared unatt'-', It was not until 1887, when the Rev. Hannibal Goodwin, an enthu siastic amateur photographer, ap plied for a patent on the first cam era film, that the dream of so many yearB was realized. Dr. Goodwin's patent, through the institution of in terference proceedings was not Is sued until 1898, but upon this pro cess all photographic films are made. On August 14, 1913, after eleven years of 'litigation, in the United States District Court at Buffalo, N. T,, Judge Hazel banded down a de cision finding the Eastman Kodak Company guilty of Infringement of the patent of Hannibal Goodwin, owned by the Goodwin Film & Cam era Co., whose sole trade agent Is the Ansco Company, of Binghamp ton, N. Y. The patent Is, under this decision, given a broad and controll ing constructioo covering the uni versally used, modern photographic film in all forms, including cartridge film, film packs and cinematograph film. Thus It will be seen that the Ansco Company and Us predecessors have been from the beginning of the development of photographic art in this country, intimately allied with its progress, being not only the pio neer makers of professional cameras and photographic supplies In Amer ica and the first manufacturers of dry plate and film band cameras in the world, but the promoters of the first successful photographic film. Behind Ansco Film, therefore, are years of experience of the highest or der, and the assertion that Ansco Film Is the original, genuine, and perfect film, is borne out by the decision of the Courts of the United States. ' An outline of the processes em ployed In the manufacture of pho tographic film will no doubt be of service as well as Interest to the Teader. The film support Is made out of cotton. Cotton fibre Is in troduced Into a bath of Bulphuric and nitric acids and undergoes the process known as "nitration," the product formed being nltrocelulose. Tho photographic cotton used In the Ansco method is the same kind that has been employed lnthe manufac ture of Anthony's Collodion for more than fifty years. The nitrocel lulose Is dissolved In alcohol, amyl acetate and fusel oil, forming a syr uplike liquid, which is generally known to the manufacturers as "film lope". I This solution Is then cast on a polished surface In thin continuous j bands after a process not unlike that of making paper from wood pulp, allowed to set so that when lifted j from the polished surface it forms a tough, pliable and Tollable skin of, even thickness. j After adequate drying the film Is coated with the gelatine silver emul-j s!on on one side, and on the reverse with plain gelatine to make the film: noncurling. This Is a feature of the; Goodwin patent. j The emulsion used to coat film Is essentially the same as that used In, th manufacture of dry plates. There, are several methods In vn?ue. al of which are Intended for definite j and certain results. Film emulsion.! as It will be used largely In Instanv taneous work, must be exceedingly teHKf! -TwUc..--rS-L- WHILE THE g r i w With New uom uoo ripe AmberineBit To Each Purchaser of a lOcPouck of DIXIE QUEEN PhigCutTobacco This "Panama" Corn Cob Pipe with genuine imported Weichsel stem and Amberine bit looks better, is made better and will last longer than the old-time corn cob.

This prevents showing any in terior picture of the works. Gelatine emulslonsi so called be cause the silver salts are suspended in a solution, the principle consti tuent of which Is gelatine, are ex tremely difficult to manufacture. Gelatine, in Itself a very uncertain substance, must undergo special pre paration and elaborate testing under standard conditions it uniformity is to he attained. The silver salt upon which the re-1 cording of the photographic Image ' depends Is silver bromide. This Is,' therefore, the most Important insre-' dient of the emulsion; but a simple gelatine emulsion employing silver bromide is incapable of producing the results which are the foundation of the success of Ansco f :? ir:. A film, to be successful must re cord accuiately the gradations of light and shade In the subject pho tographed and render the image in Its true color values. "It's the film that makes the picture," Is an as sertion that cannot be gainsaid. It is essential, therefore, In selecting a' photographic film that the purchas-i er should choose a brand that will give him the absolutely highest de-j gree of faithfulness to nature in bis picture.
