The solu-tion is now ready for use; filtering is not necessary. As statedabove, only dark amber-colored or black bottles should be employedas storage vessels; blue glass does not protect the solution againstthe actinic effects of strong light. Solution of dichloramin-T must be carefully protected againstheat, light, water, alcohol and most metals; in fact, most commonsubstances have a strong affinity for chlorin, hence the readydecomposition of this solution when brought in contact the solution becomes turbid and forms a deposit ofcrystals in the bottom of the bottle or develops a pronounced odorof hypochlorous acid it should be discarded. Fresh solutions, ifchilled, may temporarily become cloudy, or even precipitate, owingto the separation of either dichloramin-T or of solid warming the solution quickly restores its Office-preparation hot tic For office purposes it is best to keep the dichloramin-T solutionin an amber-colored office-preparation bottle with a ground cap(Fig. 100). A small glass tube kept in the bottle readily assists inobtaining the few drops necessary for each treatment, to be placedupon an aseptic glass tray. Under no condition should plierscharged with cotton, etc., be introduced into the prepaiation inthe bottle, and no unused portions of the solution must be returnedto the stock-bottle. The terminology of the substances which are used for the pur-pose of combating infection is frequently employed in a very loosemanner, and without regard to its precise meaning. Hence,therefore, it may not be amiss to give as a preamble the definitesignificance of the more important terms as they are used to desig-nate the specific nature of their action.
