MORE IMPURITIES IN CROTON.
The Analysis Is Satisfactory,
However, SAYS Dr. Martin.
He Thinks Excessive Heat May
Have Caused Fermentation.

The Croton water, according to recent
analyses demonstrated that It contain3 more
impurities than were discovered ten or
twelve days ago on The face Of the analyses
chemist Martin. OF the Boari OF Health. says

from the Croton to be apprehended.
