✦ Synopsis

have analyzed 13 samples of Irish moss (Chondrus), and found from 2 to 12 parts of arsenious oxide per million. The arsenic content therefore was in excess of the established tolerance (1.4 parts per million) for arsenic in food products; it was not uniform, even in samples from the same locality, and tended to be higher in the natural product than in the sulphur-bleached product.

Benzoyl Peroxide in Flour.--Benzoyl peroxide is used extensively for bleaching flour. When used for that purpose it is readily detected in freshly milled flour, but is found with difficulty after the flour has aged for even a few days. Apparently it is converted into benzoic acid. The quantity'of the peroxide addedto the flour will produce between 2o and 34 parts of benzoic acid per million parts of flour.
