1. Eighteen naturally-occurring amino acids and taurine have been identified chromatographically in the acid hydrolyzàte of Teredo diegensis and Bankia setacea, and seventeen naturally-occurring amino acids and taurine have been identified chromatographically in Limnoria tripunctata and quadripunctata. A spot corresponding to lanthionine has been found in the above Teredinidae living in redwood blocks but not in those living in pine blocks. Glutamine has been found in the alcoholic extract of freshly-ground Teredinidae sections.

2. Three species of wood have been hydrolyzed with acid, and all were found to contain the same thirteen amino acids.
