SI)? IMnrnt? Mm CODOS, i 9 i 8 There ' s a man in the world who is never turned down Wherever he chances to stray; He gets the glad hand in the populous town, Or out where the farmers make hay. He ' s greeted with pleasure on deserts of sand, And deep in the aisles of the woods: Wherever he goes, there ' s a welcoming hand — he ' s The Man Who Delivers the Goods. The failures of life sit around and complain The gods haven ' t treated them white; They ' ve lost their umbrella whenever it rains, And they haven ' t their lanterns at night; Men tire of failures who fill with their sighs The air of their own neighborhoods; There ' s a man who is greeted with love-lighted eyes — he ' s The Man Who Delivers the Goods. » One fellow is lazy and watches the clock, And waits for the whistle to blow; One has a hammer with which he will knock, And one tells a story of woe. And one if requested to travel a mile Will measure the perches and rods; But one who does his stunt with a whistle and smile — he ' s The Man Who Delivers the Goods. One man is afraid he ' ll labor too hard, The world isn ' t yearning for such; And one man is ever alert — on his guard- Lest he put in a minute too much. One has a grouch on, a temper that ' s bad, And one is a creature of moods; So it ' s me for the joyous and rollicking lad — for The Man Who Delivers the Goods. — Anonymous Twenty-One

CODOS, i 91 8 It is no more a question of profession, but one of patriotism, love for one ' s country and its honored traditions, respect for one ' s ideals, so it matters but little what we are called upon to do, provided we do our share. The self and the ego must be completely eliminated, for we are only part of the intricate mechanism the task of which is to create freedom and liberty. The training we have received during the last three years is now to be put to practical use. Whether it is put to actual practice in dental work or not matters little, for, aside from the training our college work has given us in our profession, it has added to that mental balance which makes men more fit to do any kind of work with greater ease. No matter in what capacity we shall aid in the war of liberation, this training will be helpful to us, even as it will be when the great victory has been won, and we shall return to take up our life ' s profession. None of us should feel that his task, whatsoever it may be, is unimportant. In a war where the world ' s freedom is at stake, where the fate of entire nations hangs in the balance, where the weak must be protected and right upheld, each one must do his best at any task, and we as college men should be capable of doing it so much the better. Every muscle must be strained to the last fibre and every mind to the last nerve, to push forward to the Great Goal, without the attainment of which, life will not be worth the living. These are the principles which have been instilled in us during the last three years, which have been devoted to making as good dentists of us as we are patriots. The highest ethical ideals are involved in both. So, when we go forth from our illma Mater within a few days, let us remember all these things; that a pro- fession is of no value unless it can be of the highest type; that the ideal of our profession now and always must be carried out in our ideal of life, in our love and respect for our country, and our willingness to aid her.

C O D O S , i 9 i 8 imottsirattott in Jugulating Appltanr? By Victor Hugo Jackson (M.A., M.D., D.D.S., New York). HE new anchorage of appliances requires that a thin, broad collar with a buccal lug of triangu- lar shape, like a door latch located to rest near the gum at the center of the tooth, be cemented to the last erupted molar on ea ch side ofthe dental arch, and a similar collar with a buccal lug be cemented to each of the cuspids, or if the cuspid is absent, the collar be cemented to one of the other anterior teeth. Often lingual lugs are used for these purposes. (See Fig. i.) When the collars are cemented to the anchorage teeth, an impression of the arch is taken and accurate models are prepared, on which an appliance is made. The metal parts of an appliance are known as partial-clasp, spring-clasp, base-wire and springs. Of each of the last two, there are several forms. The metals employed are usually of German silver spring wire. Spring wire containing more than 20j3er cent, of nickel (known as silver nickel) is generally used, and when carefully drawn it is usually sufficiently springy. A partial-clasp of 18K. gold plate-metal No. 36 U. S. standard wire gauge, shaped with a contour- ing plier, is fitted to the lingual surface of each of the cuspids, bicuspids and molars of the model on each side of the arch. The foundation of an appliance is a base-wire usually of a rather large diameter. The size or gauge of the base-wire is chosen according to the age of the patient and density of the bone. A spring-wire No. 13 U. S. standard wire G. being used for a child of four years, No. 11 base-wire for a child of eight years, No. 10 for a child twelve years of age, or for an adult; for the adult occasionally No. 9 G. is employed. In any case where the anterior part of the dental arch requires lateral expansion and the distal part of the arch does not require lateral expansion, the body of the appliance is made by arranging a large base- wire to cross the distal part of the arch opposite the last molars following the palatine curve. The ends are bent forward to form arms, extending from the last molars to the cuspids, resting on the partial-clasps near the gum on the lingual side of the teeth, to which they are finally soldered. These ends of the base-wire are made less bulky by dressing them with a file, especially near the ends, or at locations that will not lessen their strength. Twcnty- ' J ' zvi
