Numbers VIL, XIV,, XV., were known to be pure milk. 



The figures with the — sign before them sliow that this iflgredient, 

 instead of being below the normal amount, was present in excess. 



These cases, with the exception of Nos. V., VIL, XIV., and XV., 

 were all carried into court, and convictions were secured. Xo. V. it
