By the method about to be described many of these instruments are done away with and only a single burette, properly fitted, is made use of, together with an eye-dropper, preferably with a long shank to reach down in the bottle containing decinormal alkali.
The burette is made in the following manner: An accurately graduated tube whose inside diameter is from six-sixteenths to seven-sixteenths of an inch, and which holds 25 c.c., should be marked off in tenths of a cubic centimeter. The lower end of such burettes have a space below the 25 c.c. mark not etched; this
