sometimes led to valuable discoveries
in science, particularly in chemistry,
and we have recent instance in The
Chemiker Zeitung. Herr v. H. Soxfiet
was recently examining varioGs Tx
tracts Of indigo, such as indigo Gar

market value, when, by IA pure over
sight, a quantity Of Liquid. ammRDia
was poured into a glass containing
some OF the indigo carmine. The grass
was stoppered and left to ITSELF but
at the end Of ten days it was, takanup
