be avoided The danger would be less whsre the pipes are
small circumference and daily use, and greater where
there is of surface asd they have been permit
ted 10 remain unused for any considerable space OF time
The internal coating OF Tin will be secure prsteet!on
against the oxdization OF the Lead The timed eaden
pipes petitioners altogether superior 10 the ord
