EXTRACTED BY HYDROCHLORIC THE ASHES OF EACH FILTER 080018 GR Long years of experience and continuous factory operation, coupled with fortunate climatic and physical conditions, have enabled the Munktell Factory, at Grycksbo, Sweden, to supply the Chemists of the world with an unequalled product. Aside from the chemical constitution of the paper, which can, of course, be controlled by the laboratory of the factory, other constituent features can only be attained by expert hand manipulations, as, for instance, the weight, texture and uniformity, for it must be remembered that all chemists' Filter Paper must from its very character be hand made. Transient help or workmen trained in other lines of paper manufacture, especially those who have worked in factories where paper is made by machinery, can not be of much use. For generations the sons and daughters of the workmen in this factory have succeeded their parents and the same is true at this date. In this way the necessary touch" has been developed in these workers from their childhood on. 44 As the chemical industries have developed so also has this factory enlarged its line so that at the present time, as sole United States Agents, we are able to offer from stock for prompt shipment a grade of Munktell's Chemists' Filter Paper to meet any known requirement. Descriptive pamphlet, showing price and full particulars, sent upon applicaton. Samples of paper furnished on request. E. H. SARGENT & CO.
