with applications, inverse functions, complex numbers, polar coordinates,and the slide rule. Four place tables are included in the text.A number of significant features of this text are worthy of mention: the

complete treatment of logarithms early in the text, the selection of topicsin the review of solid geometry in connection with the work on sphericaltriangles, the work on circular measure and graphs, and the review ques-tions and tests at the close of the various chapters. Provision is made forstudents of different levels of ability by providing sets of exercises for theaverage as well as the above average student. The appendix offers sup-plementary material for the students who wish to do more than a minimumamount of work. This text contains adequate material for a course in highschool trigonometry. Students should appreciate the high standard of logicand the clearness and directness of the proofs and discussions.

DRUG LABELS MUST SAY WHAT THEY MEANDrug labels, from now on, are going to have a very specific meaning. On

October 10 new regulations go into effect. If a medicine is safe and effectivein the hands of an ordinary citizen, full directions for taking, including adescription of what it is good for, will appear on the package. And if it isnot safe for self-medication, or if it cannot be satisfactorily used exceptunder the supervision of a physician, it will carry the Rx legend and no ex-tra trimmings. Customers will know that if they are able to purchase a drugover the counter, it is safe when used according to directions.The Food & Drug Administration has said that Congress, knowing that

people always have and would continue to medicate themselves, intendsnot to outlaw self-medication but to make it safe. Furthermore, directionson safe medicines must be worded so that they are understandable to any-one reasonably familiar with the English language. The Food & DrugAdministration will not tolerate an attempt to obscure information behinda screen of technological verbiage.

LONG DISTANCE TELEPHONE CALLS WITHOUTASSISTANCE FROM OPERATORS

All long distance telephone operators will some day be dialing calls,directly and unassisted, straight through to the called telephone eventhough it be at the other side of the continent. This method, now in opera-tion to a certain extent, is the announced objective of the American Tele-phone and Telegraph Company, according to a recent statement made byits president, Walter S. Gifford.The ultimate aim, Mr. Gifford states, goes further, and will be reached

when telephone subscribers can dial "anyone anywhere in the UnitedStates or perhaps anywhere in the world just as simply and promptly asyou can dial the telephone of a neighbor in your own home town." Thislong-range goal, he says, is "undoubtedly many years away from practicaluse."The first plan is already in use. About 5% of the daily 2,700,000 toll

board calls are now being handled by the operator toll dialing method. Un-der this method the customer dials the outward toll operator, who in turncompletes the call to the distant telephone through toll dial equipment,usually without the assistance of another operator.
