Polarographic behavior of bismuth subgallate (Dermatol) and its allied substances was examined in detail and its result supports the structure proposed by one (Nagase) of the authors earlier. The observation of these polarographic waves will not only make their determination possible but also offer some help in their identification and purity tests. According to these experimental basis, microdeter-mination of bismuth was carried out by coulometric titration, using gallic acid.
