Regarding the ID of the bottle fragment with the embossed letters "...RESS",
the suggestion that the letters are part of "ACT OF CONGRESS" is a good
possibility. However, I believe the act of congress is more likely to refer to
the Act of Congress of 1869 than the Pure Food and Drugs Act of 1906. At any
rate, if the "RESS" does not refer to watercress or an ingredient, the bottle
will be very hard to identify, since so many medicines were made in
Philadelphia.
