GLANDERS 131 
suspicious and a reaction in dilutions of 1-800 or higher indicates an 
infection with Bact. mallet. 
As pointed out by Bonome and confirmed by Taylor, there seems 
to be little or no change produced in the precipitating power of the 
serum of the blood taken before, during or after the mallein reaction 
but the agglutinating power as determined microscopically is very 
much increased during the mallein reaction. 
This is shown by the appended table:
