Rapidily in laboratory technic depends to a great extent on the simplicity and efficiency of the apparatus; a minimum of time and inconvenience being always an important factor in any method. The following two pieces of apparatus are exceedingly simple and are recommended for their comparative inexpensiveness as well as their general efficiency. They were devised to fill a need in certain work, and were so satisfactory that I have taken the liberty to report them.
