Out of thirty two samples analyzed by this Division I found seven to contain salicylic acid in sufficient quantities to admit of qualitative proof, or nearly one fourth of the entire number analyzed. The serial numbers of these beers corresponding to those in the large table on page 282 are as follows: 4801-3-5-6-17-23-25. These were all bottled beers, one being an imported (Kaiser) beer. None was found in any of the draft beers. Of the nineteen samples of American bottled beers, six contained salicylic acid, or nearly one third. These included the product of some of the largest breweries in the country, beers that are used to a very large extent all over the United States. Whether the acid is added in the breweries where the beer is made, or whether it is used by the local bottlers, I am unable to decide. In one case I found it in the beer sold here under the brand of a large Western brewery, and sent direct to the same brewery for another sample, which gave no test for the acid; unfortunately I cannot be sure in this case that the firm in question did not know the purpose for which the sample was intended.
