It should be stated that sample No. 5 was not intended apparently for general anæsthesia ; there was no instruction, however, to that effect on the label but on another tube from the same firm the label contained the words "for local ansesthesia," and in that case the presence of "traces of impurity" is probably not a serious matter. In one instance the boiling point of the sample proved to be -0.5° C., a mixture of methyl chloride and ethyl chloride (used it may be with advantage for local
