CODOS, i 9 i 8 In designing and making movable appliances the irregularity of the teeth is carefully studied with the assistance of accurate models, and a design of a suitable appliance is determined upon. From this a pen- cil drawing representing the design is made in a duplicating book with carbon. The design is dated and numbered. One copy of the design is removed from the book to guide the laboratory man in making the appli- ance. With the appliance it is returned bearing the maker ' s name. The duplicate design of the appliance is dated and remains in the book as a permanent record for reference. Dear beloved Faculty: Midst a vale of tears We bid you farewell, Knowing it grieves you, too, To part forever from us, By your own acclamation And our own admission, The best class ever — So surpassingly smart, So beautifully behaved, So quiet and attentive — So wondrous a class, Whose members never, Never cut nor Neglected to pay Their fees on time, Nor wore a dirty white coat, Nor failed to appreciate Whimsical Will ' s solicitude IJtttjnut lEtfim? nr Season (With profuse apologies) For the weaker sex, Or cherubic Charlie ' s Eruptions of humor, Or the august personality Of most worthy Worthie, Or dilly-dally Delancey ' s Inevitable jumping On the wrong man, Or archangel Arthur ' s Munchausian tales of his Amazing memory and skill, Or haranguing Herbert ' s Eternal quest for The elusive condyle-path, Or handsome Henry ' s Sublime indifference To the size Of his audience, And so on and so on; And in conclusion We desire to say That for all You have done for us And done us for, And for all You have wished us And wished on us, We thank you muchly.

CODOS, 191 8 Spurs are extended from the base-wire to the grinding surface of some of the teeth to prevent the ap- pliance from resting on the gum. After the several parts are shaped and arranged on the model they are treated with a flux, chloride of zinc, and united with chemically pure tin as a sol der, being fused by a large soldering iron. The appliance is then dressed and polished. The appliance being made with arms and fingers in this manner permits the arms to be bent outward to cause lateral expansion of the arch, and when the teeth are sufficiently moved, causing space, these irregu- lar teeth are moved by reshaping the metal fingers, or arms, as desired. This plan of anchorage is suitable for the regulation of the deciduous or of the permanent teeth. ADVANTAGES OF EARLY TREATMENT. The advantages of early regulation of the teeth is principally for increasing nasal space, while the arches are in their developmental stage, to improve the breathing, for causing room for the proper eruption of the permanent teeth, etc., which is described with models and apparatus. The models of two cases of irregularity of the teeth of children four years of age were shown, illus- trating the condition before and after expansion and movement of the teeth with movable regulating ap- pliances. With the collection were shown models of the upper and lower dental arches of a child four years old, before and after regulating. The child had upper protrusion and very narrow arches. Accompanying the models were a record card and an upper and lower appliance used for correcting the irregularity by the expansion of the dental arches. The arches were expanded and equalized antero-posterially by the use of rubber equalizing bands. Apparatus for the regulation of various irregularities of the teeth were shown as for upper protrusion, prominence of the lower teeth and mandible, elevation and depressing of incisors, the correction of the median line of the arch, warping of the arch, etc. The use of the record card on a tracing board (Fig. 2), devised by the author, was shown and the plan described, for controlling the exact measurement of force of the appliance in each application, which reduces orthodontia to an exact science, and from its application prevents tenderness of the teeth in their movement. Additional force is applied once a week. At first make a measurement of one-half millimeter and later increase the measurement a little. The appliance is easily removed by the patient or nurse for its cleansing and for the cleansing of the teeth. : Twenty-Five

Awake, the Spirit of Eighteen Twelve! The monstrous Huns are furious, Suspending the law, in wickedness delve, Civilization — must we endure this? Awake, the Spirit of Sixty-one! The Prussian in his fury rides, Outraging women for their devotion — O Lord! why does your justice hide? Awake, the Spirit of the Day! To dominate is his devotion; Let ' s crush the Hun as the Hessian Back in the time of Washington. Awake, ye of wealth and might! The moral law must be taught To makers of war; to wrongers of right Or life ' s mission ' s worth for naught. Awake! Awake! Let us together stand, United by Liberty ' s story, And go Over the Top hand in hand, Singing the Hymn of Glory. Edward Goldstein, ' 18. Twenty-Seven
