The top is weighted, and the hydrogen passing in through L fills 
the bath, beginning at the top and driving the air before it, after 
which there is a steady flow of hydrogen through the bath, lhe 
bath was intended to dry in an atmosphere of hydrogen, but it is 
large enough to put small pieces of apparatus on the false bottom, 
and connect them with the tube L, and thus dry in a current o 
hydrogen as well.
