Excerpt from The Chemical Composition of Lime-Sulphur Animal DipsThe first series of experiments, as it happened, was directed toward a study of the stability of lime-sulphur solutions during storage. A number of prepara tions made for another purpose had been partially analyzed when other matters interrupted. On resumption of the work it seemed best to repeat all the de terminations previously executed. The results are given in Table 1, under Experiment 1.The formulas employed were based on 100 parts of sulphur in all cases, while the lime is expressed in proportional parts available calcium oxid. The pro portional parts of water given include both water added as such and the water of hydration of the lime. The lime and sulphur were thoroughly mixed dry in the container in which the solution-was to be prepared - a 500 c. C. Kjeldahl ¿ask. The desired amount of water, usually 200 c. C., was then added gradu ally with thorough mixing. The mixtures were brought to boiling under re¿ux in about five minutes, and only the period of actual boiling was counted. Shortly before the end of the boiling period, during which the ¿ask was fre quently shaken, a stream of illuminating gas washed through caustic-soda solu tion was introduced through a narrow tube passing down the condenser into the neck of the ¿ask. The ¿ask was partially cooled under these conditions by immersion in water, then the well-mixed contents were transferred to 4-ounce sample oil bottles, which were filled into the necks and sealed. When cold the bottles were thoroughly shaken to insure a uniform solution.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
