A pieceof heavy pure rubber tubing about 25 bore is stretched overthe bottom of the titration chamber and the projecting end wiredtightly around the neck of the bottom piece. Mercury is thenrun in to cover the exposed rubber, thus ms-king a mercury sealjoint. The side-am M is the outlet for ^lu^ioiis.

This tube is bent upward and ends with a cup,K,about even with the top of the chamber. About 5 c^m. from the topof the chamber are two more side tubes, M and M.

About 1 c,m. from the inside v/all of the chamber,each is bent downward for about c^m., thus making a inside dicmieter of the latter i
