of exercises and reading assignments seems adequate though shoprvorn. While chapters have been rearranged and cambined and sections deleted or rewritten. friends of the previous editions will he disappointed to see mostly the same old exercises. The hook appears to this reviewer to be highly readable, an indiapensable quality in any textbook for the beginning course. The appendix includes a table of &place logarithms, solubility products, solubilities ai salts, vapor pressures of water, metric units, and a review of arithmetic. JACK W.EICHINGER, JR.

A C C ~ ~ D I to N GJules Verne, Captain Nemo in the year 1866 sailed his Nautilus twenty thousand leagues under the sea. He used sodium to make it go. On page 324 of the volume being reviewed, we learn that todav's Nautilus also uses so-
great many practical applications to arouse interest, especially in the last quarter of his text which follows the chapter on organic chemistry. Unfortunately, few of the students taking chemistry for "cultural" purposes have developed an absorbing interest in technology 80 that other devices should be employed if a direct interest in the study of chemistry is to be developed. Stripped of vagueness and ambiguity, the ides, that liberal arts students can study chemistry with profit means that chemistry has an intelleotual content. That is to say, it typifies one of the extremely successful ways that civilized man has used to cope with his environment. Basically, this power has come from understanding which makes possible prediction and control. Long-lasting lacquers and soapless soaps have come along with this understanding, hut from the point of view of the teacher the understanding of chemistry is the important thing. This means that in a textbook for the general student an interest in the subject must first be aroused, znd then the outlines of the subject must be presented as vividly and as clearly as possible. The clearest presentation is one that sets before the reader the relationship of one part of the subject to another so that he is able to see how the members of the framework are linked. I n the present book the relationships are all there of course, but only b,v implication. For example, on pages 181-2 (Continued on page Ales) JOURNAL OF CHEMICAL EDUCATION
there is an excellent explanation of pH. However, the relationship to Arrhenius theory is not given even though the chapter begins with a description of classical ioniaation theory. To be useiul to the student who will study no more chemistry, his textbook should also help him to see links between pH and: the periodic system, the atomic theory, the kinetic molecular theory, and the electron theory BENTLEY EDWARDS U~rvms1~ or7 C*~rronrr* B ~ ~ K ~ LC*~lronm* EY.

THE manual consists of 65 experiments arranged to accompany the authors' text, "The Fundamentals of College Chemistry"; however, the experiments are of such nature as to allow a marked degree of flexibility in the choice of order and number. Most o m be completed in from two to three hours. A reasonable number are quantitative in nature. A brief treatment of qualitative analysis is included in the last eight experiments and these could be incorporated into the regular sequence of experiments. The reviewer was aamewhat disappointed in the brief and inadequate discussion of the use of the balance and in the tendency for the labomtor.v manual to follow the "work book format" so common to a great majority of the manuals currently being published. Included in the appendix are helpful tables on common properties of the elements, valences, solubility rules, activity series, and equipment and chemical lists required for the experiments. THOMAS C.
