Excerpt from Reply to the Report of Mr. Glenn Brown on Experiments in Trap Siphonage, at the Museum of Hygiene, U. S. Navy Department, Washington, D. C

It would be useful to extend the tests at the Museum of Hygiene by using vent-pipes 1 inch, Ii inches, and 15 inches in diameter, as used in practice, and varying in length between 5 and 25 feet. Such tests would then correspond with those made by Messrs. Putnam and Rice for the Boston City Board of Health, and with those made at wvorcester by the Worcester master-plumbers, in both of which series of tests ordinary traps fully vented lost their seals under siphonage no stronger than that applied by Mr. Brown, while unvented antisiphon traps held their seals under the same tests.
