Abstract
THE present shortage of potassium makes it necessary that chemists should take every care that there is no undue waste of this material, and it seems to us that with the large number of workers using the saturated calomel electrode1 for making pH measurements, there must be a considerable loss of potassium chloride resulting from the frequent flushing of the liquid junction. The use of normal and decinormal potassium chloride cells would do much to avoid this waste, but they are neither so quickly prepared nor is the conductance of the cells so good as that of the saturated type.
