This discussion is occasioned by two notes in the October 1969 issue of the Mathematics Teacher, one a letter to the editor from Barbara Almli on page 446, and the other Philip Peak's review on page 477 in his “Have You Read …?” section of T. A. Brown's “A Note on ‘Instant Insanity’” (Mathematics Magazine, September 1968, pp. 167-69). Each of these items describes the puzzling challenge known as “Instant Insanity.”

Justice Systems

In this Letter to the Editor, we aim to compare the Canadian and the French forensic psychiatry system. Comparing both systems is interesting because France is considered as one of the oldest modern justice systems, and many of the forensic concept are inherited from it or its European neighbours. On the other hand, Canada is one of the countries where the modern forensic psychiatry is born, implementing the actual scientific concepts of criminology. Although the overall goal of the Justicer system and Forensic Psychiatry is the same in both countries, the theoritecal and practical differences help each professional to reflect on their own practice in their jurisdiction.

Causes Of Violence

In response to Dr Blackman: Dr Blackman's letter confuses several distinct issues: 1) gun exposure of children seen in pediatric practices, 2) teen gun use, 3) the root causes of violence (eg, poverty), and 4) his model of "a stable and moral family environment." Our paper addresses only the first issue. Guns in the homes of pediatric practice attenders are not the cause of all of society's ills, nor of all gun violence. On the other hand, guns in the home are a proven hazard,1-4 which pediatric counseling may help to reduce.

The Right

My sincere thanks and appreciation for the new spine on Pediatrics—this is exactly what was needed. As I have responsibility for filing and finding my pediatrician husband's journals, this will save a great deal of time in often futile searches for just the right issue. I've even colorcoded the spines of back volumes as an aid, and occasionally thought of writing to request what now appears in 1970. Now if only all the other journals would simplify their spines in bold, dark lettering. . . Many sincere thanks—it was about time we had a break.

Mathematical Literature

This is the beginning of a new department in The Mathematics Teacher. This department has a purpose. Its aim is to assist the classroom teacher in putting color and life in everyday teaching. There are many ways and means how this might be achieved. Generally, recreations are supposed to introduce elements of interest and motivation. On the other hand, recreations, as they have been known in the mathematical literature for centuries, have been centered around the puzzling and the play with mathematical operations. This may be interesting, but only for a while. Soon the interest in such things may wear off. This acts as a warning that we should not become too enthusiastic over such types of recreations. If we teach mathematics from such recreational points of view only, we may obscure the more important aims of the mathematical instruction.

The mumps neutralizing antibody titration as performed in our laboratory accurately predicts susceptibility to mumps. No patient with a titer of 1:2 or greater has subsequently become infected. When a group of children was exposed to mumps on a long-stay hospital ward, every seronegative individual subsequently excreted virus, developed parotitis, or both.1 On the other hand we know of numerous skin test positive individuals who went on to develop mumps. The results of our study indicate that placebo reactions cannot account for all of the discrepancies in the mumps skin test.

We asked Dr. Alpert to comment for the Subcommittee. He writes: Thank you for the opportunity to reply to Dr. Lin-Fu's letter. She makes several important points. The thrust of the committee statement was with clinical diagnosis and the treatment ment of lead poisoning. We must make a distinction between asymptomatic increased lead absorption and increased body lead burden on the one hand and lead poisoning on the other. A mass screening program should be designed to pick up the child with asymptomatic increased lead absorption or increased body lead burden prior to the appearance of actual lead poisoning.

Starting Point

1. Professor Alföldi and the Roman Contorniates. In a letter to the Editor of this Journal Professor Alföldi has pointed out that I misrepresented his remarks apropos of the New Year and Roman medallions on p. 40 of his Die Kontorniaten, when I stated (JRS 1945, 118) that he declares that all the bronze medallions were New Year gifts. This, I now see, certainly was an inaccurate statement, for which I owe Professor Alföldi an apology. For actually he allows that the medallionissues, once begun, could be extended to other imperial festivals (‘einmal angefangen konnte die Prägung solcher Medaillen auch auf andere Kaiserfeste ausgedehnt werden’). But he does say that we may seek the starting-point of the whole bronze medallion-series in ‘show’ New Year issues, which were thought of as artistic presents for persons of rank (‘wir möchten aber noch viel weiter gehen und den Ausgangspunkt der ganzen Medaillonprägung in Bronze in solchen prunkhaften Neujahrsprägungen suchen, die als kunstvolle Geschenke für vornehme Herren gedacht waren’). That a large proportion of the medallions, taken as a whole, were undoubtedly struck as New Year gifts I fully agree. I am not, however, convinced that we have evidence that the custom of giving New Year presents set going the whole idea of issuing medallions. Apart from Hadrian's silver Felicitas type, which may possibly refer to New Year luck, our earliest gold and silver pieces, of Augustus (Diana, Principes Iuventutis (if genuine)), Domitian (Minerva, Germania), Trajan (Adventus, Providentia Senatus), and Hadrian (Juppiter), contain no obvious New Year allusions; and of the earliest bronze types, those struck under Trajan and Hadrian, only a small proportion—four (New Year formula in wreath, Hadrian in zodiac frame with Seasons, Four Seasons, Tellus with Seasons) out of the seventy-four types known to me—seem to allude specifically to the calendar New Year, and the first two of these may allude to the regnal New Year. Some of the other types of these two Emperors may have been issued at the New Year, but we have no proof of it. There were other public and ceremonial occasions equally suitable for making presents of this kind. New Year allusions on medallions gather volume under Antoninus Pius, Marcus Aurelius, and Commodus; but not all of these can be connected with the calendar New Year, and types with a wide variety of other associations still abound. It was not only at the New Year that gifts of coins were made (Suet., Aug. 75); and there would seem to be no reason why a whole range of occasions and contexts, of which the New Year was but one, should not have been envisaged for medallion-issues from the start.

The Relationship

In the article “Intuitive Approach to X0 ≡ 1” by Curtiss Mallory (The Mathematics Teacher, January 1967, page 41), two approaches to the definition X0≡ 1 were suggested, one depending on the relationship am · an = am + n, the other depending on the pattern that occurs as one writes a sequence of descending powers of some (nonzero) base.

General Setup

Consider the interesting geometric construction given by Manuel Santos-Trigo in the “Technology Tips” in the January 2004 Mathematics Teacher (Santos-Trigo 2004). He starts with an ellipse, its center point O, a variable point R on the line along the major axis of the ellipse, and variable points S and S', which are points on the ellipse that are reflections with respect to the major axis. Figure 1 shows the general setup and various placements of S. Santos-Trigo constructs a pair of lines, one through R and S and the other through O and S'. He describes a set of discovery exercises involving the locus of points generated by the intersection of these lines as the point S roams around the ellipse. The empirical conclusion of these exercises is that the locus is a conic section, the nature of which is determined in a fairly simple way by the location of R relative to O and the major vertices of the ellipse.

Proof has traditionally been the touchstone of mathematics—that which distinguishes it from the other sciences. The role and nature of proof in a Standards-based curriculum merit reexamination in an era of reform. In 1998 a fall issue of the Mathematics Teacher will focus on the theme of proof in all aspects of secondary school mathematics. The Editorial Panel is seeking manuscripts for this issue.
