Shell Fish
To Choose Oysters
Insert a knife, and if the shell instantly closes firmly on the knife, the oysters are fresh. If it shuts slowly and faintly, or not at all, they are dying, or dead. When the shells of raw oysters are found gaping open they are fit for nothing but to throw away, and should not have been seen in the market, as they are quite dead and decomposition has commenced. Clams the same.
