In 1917 the Department of Agriculture seized products from the Southern Pharmacy in Washington, D.C. and prosecuted the pharmacy owner, George R. Ridgeley, for selling adulterated and misbranded goods. The substances seized included Chloroform Liniment, Citrate of Magnesium, and Camphor. The state was able to prosecute the manufacturer by showing that their goods did not meet the standards in the USP. Notice in the deposition that after the defendant admits to making his Elixir of Iron from a non-official private formula, the attorney reminds him that he would have been permitted to use this private formula, had its deviation for the USP standard been listed on the label. This is an example of the intended use of the variation clause in the 1906 Pure Food and Drugs Act.
