The publicity given in the daily press to a cablegram alleging that lemon juice was a powerful germicide, with especial reference to the typhoid bacillus, has led the health department to experiment, with the following preliminary results:

The following experiment was made in the laboratory to test the value of lemon juice in destroying the typhoid bacilli: One hundred and twenty c.c. of bouillon was inoculated with the Bacillus typhosis. The flask was placed in the incubator at 90 degrees for 12 hours. At the end of this period 4 c.c. of lemon juice was added. At the end of four hours plates were inoculated from this flask. The plates at the end of 24 hours showed no growth.
