CHLORINE WATER. BY J. GEO. SPENZER, Cleveland, O. QUERY No. 33.-At what rate does decomposition proceed-Data are wanted as to its keeping qualities under varying conditions. The keeping qualities of chlorine water depend principally on the manner of its making and the method of keeping it. I have seen chlorine water kept in amber cork stoppered bottles useless in two or three months, when kept in cool dark places; while if kept in amber glass stoppered bottles and opened from time to time it will be quite strong in six months. If prepared according the U. S. Pharmacopoeia it will keep for a year. I have a few suggestions to offer which may have some merit, i. e.: If the distilled water be first boiled to expel air and then cooled out of contact with the same, thoroughly saturating the cold water with chlorine, filling small amber glass stoppered bottles with the chlorine water, driving out any air with a stream of chlorine and stopping the bottles with stoppers greased with tallow, the water will keep from one and a half to two years. Chlorine gas itself can be kept in this manner for two years. Chlorine water gradually decomposes as air is introduced in dispensing; but if kept in small well stoppered bottles as directed in the Pharmacopoeia it can always be had fresh. Another suggestion which is very serviceable is Winkler's method of furnishing chlorine from chlorinated lime. The chlorinated lime is mixed with plaster of Paris made into a paste with water and formed into balls and dried. These are then used with dilute acid in any of the forms of common generating apparatus. Used in this manner it should displace to a certain extent the old method of heating black oxide of manganese and hydrochloric acid together. LEAD PLASTER BY HERMAN KOEGEL. QUERY NO. 45.—Is Lead Plaster made from Lard Oil or Cotton Seed Oil as good as that made from Olive Oil. 3 5 2 Having tried the U. S. P. process for lead plaster with the various oils mentioned, find that made from lard oil to give best results. The first two batches being pound each in weight when finished, were made from olive oil, the process requiring from five to six hours for complete saponification; this was a very good firm plaster, and after keeping eight weeks wrapped in wax paper, as we receive the commercial plaster, became oxidized to extent of 2 per cent. The reaction as given 2 C3 H5 3 (C15 H33 02)+3 Pb 0+3 H2 0=3 Pb 2 C18 H33 O2+2 C, H, 3 HO, the glycerine I separated from plaster by kneading on a slab under a stream of water, this formed a white, firm plaster, that made with lard oil gave much better results, the process requiring only three hours for complete saponification, forming a very white and firm plaster, when finished on keeping eight weeks, the oxidized portion amounted to 5 per cent. The plaster made from cotton seed oil does not saponify as well and the process took up ten hours. After keeping for eight weeks was still very soft and of a yellowish color; thinking this due to faulty manipulation, made up another batch, which proved to be the same under like conditions; this may be due to the fact that cotton seed oil is a drying oil and lard and olive oils under same conditions caused no trouble. After testing samples for uncombined PbO with warm oil turpentine found none in those made from olive and lard oil, but found a small trace in that made from cotton seed oil, the one sample being free from uncombined PbO. Examined several commercial samples of lead plaster for uncombided PbO; three samples contained from .5 per cent. to 2 per cent., while three more contained none; these were put up in wax paper with a yellowish wrapper. Am convinced that lead plaster made from lard oil, proportions same as officinal, substituting lard oil for olive oil, is better adapted as to keeping quality, and consuming less time to manufacture, also being much less costly than if made from olive oil, and as to the therapeutic value answers as well.
