 sition, the minimum percentage of all ingredients for which efficacy 

 is claimed, and under the term " inert ingredients," the maximum 

 percentage of such, collectively or separately, when they exceed 

 5 per cent. The percentage amount shall be by weight in solid 

 remedies, and in grammes per 100 cc. in liquid remedies. A semi-

 .percentage amount of water-soluble arsenic.
