With the treatment of 30 courses in today's issue the Crimson continues its policy of reviewing courses in the Faculty of Arts and Sciences open to undergraduates. The editors assume no responsibility for the criticisms: they represent merely the opinions of a few upperclassmen. It has not been possible to foresee changes in the courses from year to year.

This is the Sixth Confidential Guide to Courses printed in the Crimson, and constitutes the most complete guide to courses starting the second year which has been prepared since its inception. It does not pretend to be a complete survey of these courses however, but includes the majority of important ones which a considerable number of undergraduates would be inclined to take.

Anthropology A

For those who have taken Zoology 1 or Biology A, or those interested in scientific discussion. Anthropology A should prove to be a thoroughly interesting course in which they will find little difficulty.

Human evolution, as the course is described in the directory, offers and excellent opportunity to make use of the great mass of evidence included in such courses as Zoology 1, Paleontology 1 and Geology, and apply it to a widely-discussed theory, a theory with which all should be acquainted; namely the theory of organic evolution.

As might have been supposed, this subject requires quite an extensive study of the evidences from zoological classification, embryology, paleontology, and geographical distribution of both the ancient and the present relations of man. This is done in Anthropology A without requiring too much detail which would be boring as well as more difficult. On the whole, the lectures are interesting and even amusing to some, while the reading includes selections from such authorities as Darwin and Neman, both of which are well worth while and not too technical.

Chemistry 22

For those who delight in pouring paradimethyl aminoazo benzene into metadiaminodiphenol sulphonic acid, and watching it turn pink, this course is ideal. If you prefer sky blue add a little trinitro-toluene instead.

Three afternoons a week is the minimum time allowance for Chemistry 22, and those of us who aren't so bright usually spend four. But it is one of the most interesting laboratory courses open to the undergraduates, and if one is at all fascinated with the complexities of organic chemistry it should prove a very worth while course. It is fully as interesting as Chemistry 2 is dull, because here you are dealing with the things themselves, and pot merely with their names.

Chemistry 33

Chemistry 33 is primarily for those concentrating in chemistry or those who have passed Chem A or B and wish a further knowledge of inorganic chemistry. It is intended to show, by means of an extensive laboratory schedule, the properties of the common elements and their typical reactions, and, through the lectures, a more thorough knowledge of the theories discussed in more elementary courses.

The laboratory requires a great deal of time and study, for it is one course where one must know exactly what the procedures are for and what to deduce from the results. Much difficulty is usually encountered in separating the different elements and often positive results are obtained for elements not present. Consequently one must know thoroughly all tests and impurities that might produce these tests.

There seems to be no alternative to this course for those required to take qualitative analysis, but any who do not need it would do well to look elsewhere for an advanced course in organic chemistry. For the former class it will be interesting to hear that some think the management of the course far better in the first half year when the same course is given under the heading of Chemistry 3

Economics 4b

Professor Dewing has written a book on the Financial Policy of Corporations which is so formidable that it may scare off the average undergraduate who does not know that Professor Dewing's lecture delivery is one of the least puzzling in the College. Most undergraduates on the first day of the course look wildly around for the nearest exit, convinced that they have wandered into a philosophy lecture. Bailing his trap with a summary of the corporation from Rome to the present day. Professor Dewing has the class following him, at a distance of several sea leagues, by the third lecture. Then he hops briskly to the present time, and proceeds to probe into the motives of the business man. The wheels of the large corporation, the relative advantages of the various forms of business enterprise, the actions of the stock market and the types of securities, in rapid-fire succession. Even future professors of Sanskrit, now undergraduates, would do well to take this course in order to learn where their breakfast bacon comes from, and why Bacon, Preferred sells around 30 these days. Dr. Opie will alternate with Professor Dewing, and what Professor Dewing does for the corporation's past, Dr. Opie may be expected to do for its future, showing how modern trends to consolidation have not yet run their course.

Economics 6a

For those who are interested in the ever present problems arising from the conflict between capital and labor, Economics 6a presents an admirable summary of the most vital issues. This course, given by Professor Ripley for many years, was taken over by Professor Persons of Boston University last year. The latter instructor, however, was called to Washington this fall to take up a government position as an expert on the question of unemployment, and to date no successor has been announced for the course.

Regardless of whom the instructor may be, the subject matter of the course dealing with strikes, governmental control of labor policies, arbitration, unemployment, and other problems closely associated with the labor question should prove valuable to all who have any interest in current problems. For those who think courses in Economics too theoretical, Economics 6a is an excellent corrective, for throughout the half year, one is constantly finding instances in the daily newspapers with which the week's work is directly concerned. For those concentrating in labor problems, the course is indispensable, since it takes in a wide field which would take many hours to cover in tutorial conferences.

Economics 7b

This course on the various programs for social reconstruction limits itself to fairly modern times. No undergraduate alive, whether he was born a little Lib-e-ral or a little Conserve-a-tive, can afford to be ignorant of the social ferment which goes on in the world around him, and theatens to involve him as employer or employee, taxlevyer or taxpayer in our time. This course will not introduce him to the manifestations of these doctrines now current in Harbin or in Gastonia, but it will enable him to learn something of the ideas held by anarchists, social-
