liours killed a guinea-pig, the animal dying of typical anthrax 
within four days. 
Mercuric Chloride. — A 1 per cent, solution acting for twenty-four 
hours seemed to destroy the spores — that is, they did not grow in 
sterilised solptiQiis. Nevertheless spores thus treated, on injection 
hy Dr JClein into a guinea-pig, destroyed it within four days, with 
all the symptoms of typical anthrax, 
The conclusions to be drawn from this reseamh are that anthrax 
in the spore state, instead of being a suitable “ reagent ” for testing 
the germicidal powers of disinfectants, is so extraordinary in its 
powers of resistance to chemical agencies, that few solutions attack 
it, and those that have any influence must be used in a state of 
concentration, which in ordinary disinfecting operations could never 
be attained,
