Abstract

THERE is always a tendency among students of analytical chemistry to value their work by its quantity and the nearness of their results to what is assumed to be correct, and in this they are often encouraged by those who have the direction of their studies. They do as they are told in their text-book—weigh out so- much, dissolve in 200 c.c. of water, add 20 c.c. of a stock reagent, heat to boiling, wash three times by decantation, and so on; and in the end, though they get an excellent result, they have learned not so much chemistry as if they had made an apple dumpling by intelligently following the instructions of a cookery book.
