you are very nearly, if not absolutely, right in accepting as true Dean Sangren's statement, as follows: "When high school counselors and teachers, themselves, have suflicient personal interest in and respect for their own profession, more desirable candidates will be directed into the field," although this statement fails to mention the persuasion (almost coercion) exercised by many high-school principals in recruiting their most promising students for entrance into a college or colleges in which the principal has an interest, usually as an alumnus. With your general observations I have no quarrel, but I feel constrained to utter a protest so far as Rhode Island College of Education may be concerned. In the first instance, ten years ago the State Department of Education in Rhode Island gave serious consideration to the problem of teacher supply and demand. Careful statistical studies of the number of "INTRODUCTION TO INORGANIC teachers needed annually for new positions and reCHEMISTRY" placements were made. The Department accepted as a principle of efficiency and justice that the State To the Editor should not train more teachers than were needed. So DEARSIR: far as the State was concerned, the application of In the December, 1935, number of the JOURNAL OF justice affected the taxpayers, who should not be asked CHEMICAL EDUCATION on p. 599 is published my review to pay for the education of persons who could not find of G.

duction of the elements of precision in a first-year course in chemistry one can hardly do more than point out the significance of precision in obtaining measured quantities, the meaning of "significant figures" and "percentage precision" and the application of these relatively simple concepts to operations of measurement, multiplication, and division. Even these are difficult enough for first-year college students. Only a small percentage of them understand the principles well enough to continue to apply them intelligently in their experimental work and in the solution of problems. WALTERR.
