A correspondent has transmitted to the editor of L'Union Pharmaceutique the prospectus of an oyster dealer who, besides dealing in the ordinary bivalves, advertises specialties in medicinal oysters, such as "huitres ferrugineuses" and "huitres au goudron." The "huitres ferrugineuses" are recommended to anĉmic persons, and the "huitres au goudron" are said to replace with advantage all other means of administering tar, while of both it is alleged that analyses made by "distinguished savants" leave no doubt as to their valuable qualities.

This produces a current of hot air in the chimney, which draws up the smoke and gas at once.
