la ry teeth." Th e fa ct that t he committee in sist s up on occlus ion r eferring to teeth in contact makes it necessary to introdu ce t he term "abocclusion " because the r eport of the commit tee says, "in certain flesh eatin g mammals th e ma xillary and mandibular premolar s ar e n ever in contact." \Ve presume t hat the committee r efers to occlusal contact as bein g a distinct po siti on f rom proximal cont act. \ Ve can see no r eason th at t he t erm occlusion should be so limited in describin g the r elati on t he t eet h of one arc h bear to t hose of the other as t o make n ecessary the new t er m, abo cclusion . The term occlusion describes p erfectl y such conditio ns as t he committee tries t o pl ace under abocclusion. In describing th e occlusal cont act r elati ons of t he t eeth of man, the committee has very nicely illust rat ed the contact r elations which go to mak e up the occlusion of th e t eeth of man, as follows: First , the surface contact. Second, cusp and fossa contact. Third, ridge an d embr asur e contact, and fourth, ridge and groo ve conta ct . However, th er e are gr ounds for confusion wh en the committee suggests that these occlu sal contac t r elationships may be te r med "fact ors of occlusion" because of t he possibility of the students confusing "facto rs of occlus ion" with "forces of occlusion" which has had an acce pted usage in orthodontic literature f or a num ber of ye ars . Th e plan used in describing normal occlusion inv olves a large amount of ma t hematics and would mak e it n ecessary fo r one to under stand a system of calculat ion such as is followe d by the editor of the r eport to be able t o int erpret the definiti on of normal occlu sion. 'I'o our mind it seems as if t he term s " nor mal occlusion," " infer ior normal occlusion" and " superior normalocclus ion " ar e going t o cr eat e mu ch more conf usion than some of the definiti ons whi ch t he r ep or t of t he committee t ends to displace. H owever , with the t yp e of dent al education whi ch is bein g advocate d by the National Educati onal Council in which the dental students are to be taugh t almost everything except dentistry, it is very possible that a lar ger cour se of mathematics may be in cluded to enable the stu dent to understand the differ ence between inferior normal occlusion and superior normal occlusion. The report of the East ern Association of Gradua tes of the Angle School is one which has been p repared as the r esult of th e great amount of st u dy and deliberation , and is more satisfactory t han any report which has been presented along simila r lin es. The r ep ort, wit h th e objections given, we r ecommend for th e careful stu dy of our r ead er s.

experiences and ideas, also the operations described have been evolved by him." The author seems to have very little time for use of nitrous-oxide and oxygen. This is unfortunate as most of the best practitioners today in exodontia, depend upon gas-oxygen to accomplish their best results. The chapter devoted to vaccine-therapy is of interest but is too little understood, as yet, to recommend to the student. There are some errors in orthography through the volume which no doubt are typographical.
Us Kids Have All the Trouble I'm N at Just But
just a kid with crooked ivories, a little enough to cause the worries, that I'm one or two a-stickin' out, :1 little bit our dentist says without a doubt, my
out of line, havin ' at this time. too far, mug they surely mar.
So rna and dad have taken me, before it is too late, Never listenin' to my plea a few more months to wait, To the darn ole orthodontist, with wire, an' rope, an' bands, Who will try his darndest, accordin ' to his plans. To pull 'em out in better shape, he's a-gain' to try, Says I look like "ole Darwin's ape," I wonder who's that guy. So now my trap's all bound and tied, like Houdini in the show, An' when I open it real wide, you can see its golden glow. The kids who live upon our street, all josh when I appear, To see my mouth it is a treat, an' call me "mamma's dear." With a thousand little jiggers, all pullin' their own way, This orthodontist figgers, he'll have 'em straight some day. And although it is an awful bore, to go just a.f'ter school, To spend a half an hour or more, bein' picked at with some tool, I suppose my rna an' dad are right, the orthodontist too, As who would want to be a sight, like ole Jacko in the zoo. So bet your boots yourc findin' me, a-keepin' As I don't want my teeth to be a-stickin ' right I want 'em tucked right up in place, an' even So I won't have a baboon face, an' worry all
