Antilis trap is a notableinstance of this kind. Amateurs, as a rule, have miserably worst idea broached in connection with traps was by a dentist,who recommended a tight joint of vulcanised indiarubber made by ahinged and weighted flap fitting down into a prepared groove. Therewas no water trap, no ventilation. The greatest improvement inlead syphon traps, for closet soil pipes, was brought out by a NewYork artizan, named Lowe, who invented a means of casting a trapwhole, and pointed out the construction of a wooden core which couldbe easily withdrawn. Previous to this, lead traps had been solderedtogether out of two bent half pipes, and the consequent stretching atthe bend rendered them easy of breakage, being too thin where theyshould be strongest. PECULIAR TRAPPED 122. 123. 124. 125, There is a peculiar system of self-acting trap, which I draw atFig. 122 ; but it has not been used of late years, owing to the intro-duction of better kinds.
