Excerpt from Bulletin of the United States Fish Commission, Vol. 10: For 1890 Some unavoidable use of brass piping in the beginning demonstrated beyond any further need of experiment the necessity for the entire absence of metals from the tanks, reservoirs, and circulatory apparatus, and consequently the materials now used in their construction are glass, slate, hard and soft rubber, and wood, nothing being used which is oxidizable or capable of exciting galvanic or chemical action.
