Certificates were received from Mr. Gabriel Bayfield, 
No. 9, Park Place, Walworth, and Mr. William Ed-

Cathery, and find it to answer better than gall in a liquid 
state ; that this preparation is free from disagreeable 
smell, and is much cheaper, as one ox-gall thus prepared 
will last one person for two years, and be as fresh as if 
just taken from the ox. 
A Certificate was received from Mr. James Stewart, 
No. S6, St. Martin’s Street, Leicester Square, stating, 
that he lately belonged to his Majesty’s ship the Yestal 
frigate, and that he took out with him, in a voyage to 
Newfoundland, a large pot of the prepared ox-gall, for 
the purpose of washing his greasy clothes for two years ; 
that he found it very serviceable, and to keep its virtue as 
well as the first day.
