president-elect for 19-12 at final sessions of the seventy-second annual convention of the Virginia State Dental Association at the Chamberlin Hotel yesterday Dr John Roanoke was re-elected secretary-treasurer Dr Allen of Berryville was elected as delegate at large to the executive council and Dr Muir Roanoke and Dr Bagley Walker Norfolk were re-elected to the council Dr Via Dr Goad Dr John and Dr Hodgkin Warrenton were chosen to represent the Virginia association at the national convention of the American Dental Association Richmond was selected as the 1912 meeting place and next convention will a celebration of the Itrnth anniversary of the organization of dentistry in Virginia Shaking on (niitont iwychology and general office practire at the final sessions Dr Norman Dcn-ncr Cleveland Ohio president of the Cleveland Dental Society declared that complete confidence of the patient in his dentist is the chief requisite in a successful practice He said all patients hate dental appointments but few realize that a few minutes in the rii-nf ist'a chair can save them many jnssihle hours of pain later In discussing the relation of the teeth to the emotions the speaker said "Every emotional reaction lias some sort of dental expression When we are elated we show our teeth In a smlie When we are depressed we hide them: when angry we gnash them when determined we grit them and when we are frightened they Wart Disease Of Wild Deer Is Increasing WASHINGTON (Science Service) A sudden increase in the widespread incidence of a serious tumor-like disease of the deer throughout much of the big game country during recent months has caused wide-spread alarm among game managers Cases of infection have been discovered from Oregon to Maine and south to Georgia The growths are fairly prevalent in the Carolina deer and scattered cases have been found in surrounding States A few infections have been reported from the Pacific Northwest In Maine numerous instances of infection have been recorded from the Isle au Haut some from Argyle township two from the region around Cherryfield one from Mt Desert Island and yet another from the Gaucomgomac Lake area In that State at least are not new concern was expressed several years ago when dead deer were found heavily infested with the growths The commonly assume the size and shape of an ordinary tumor appearing more often in multiple form than singly Usually the head and neck are most heavily infected The body end legs however are not free from attack and quite often deer dead of these tumorous growths have their bodies and limbs literally covered Sometimes the animal's sight is materially impaired and not seldom the hearing is completely destroyed by growths in the ears Tick May Be to Blame The manner in which the warts are transmitted is unknown Although the contagion is more or less taken for granted they may not be directly transmissible An intermediate host may be necessary it is quite possible that some vector perhaps the common wood tick is responsible for the spread of the disease As yet however even the causative organism has escaped detection Bucks and does are equally susceptible and though the whitetailed deer are primarily concerned it is suspected'vjhat mule deer and Pacific black-tails are equally vulnerable April Fire Loss Heavy WASHINGTON (Science Service) Forest fires during the month of April swept over more than 1-300000 acres of timber land principally in the South and East figures compiled by the National Wildlife Federation indicate Translated into terms of lumber the destruction comes close to 300 million board feet or enough to build baracks for nearly 200000 soldiers DENVER (Science Service) The theory of meteorites made of matter" which explode and vanish when striking ordinary matter is not necessary to explain the failure to locate meteoritic fragments around certain craters which seem to have been produced by the impact of giant masses of stone or rock from the sky says Dr Nininger director of the American Meteorite Laboratory here He expresses his views in a report to the Society for Research on Meteorites The theory of reverse or "con-traterrene" matter was proposed about a year ago by Dr Vladimir Rojansky of Union College Ordinary matter is made of atoms having nuclei of positively charged protons and negatively charged electrons revolving around them Contraterrene atoms on the other hand if they exist have negative nuclei and positrons electrons with positive charges revolving around If ordinary and contra-terrene matter were to come into contact the charges would cancel and both would disappear in a violent outburst of energy Theories Are Advanced Following this proposal it was suggested by Dr Lincoln La Paz of Ohio State University and also by Dr Samuel Herrick Jr of the University of California Los Angeles that contraterrene meteorites sometimes land on the earth Dr La Paz's idea was that they might have caused craters like those at Tunguska Siberia which seem to have been the result of meteoritic impact in 1908 even though expeditions have found no meteorites in the vicinity Dr Herrick made the proposal that a contraterrene meteorite was responsible for the "phantom last summer when a boating party in Long Island Sound were startled by what seemed to be a shell fired across their bow hitting the water and exploding near-by It was shown however that it could not have been a shell Dr Nininger Comment Without comment on whether or not contraterrene matter may exist Dr Nininger declares that either the meteorless craters of the mysterious can be explained assuming the existence of any such purely hypothetical He says that if even the famous Arizona meteorite crater near which many tons of meteorites have been found had been formd in a partly swampy and wooded area like that of central Siberia probably not a single meteorite would have been found The story of the "phantom he declares entirely consistent with an ordinary daylight OLD TIMERS AT DENTAL CONCLAVE Dr Frank A Lee of Lynchburg oldest practicing dentist in Virginia and Dr James Lester of Richmond who missed a convention

question dealing with a concrete prob-blem of leadership For example: "How would you plan a trip from Berlin to attend the Germany-England football game which will take place in two Next comes a

light a light with a circle and ore with a square can be shown Furthermore twro rattles may be sounded one from the left and one from the right The observer sitting in front of the screen has three hand levers and two-foot pedals to operate The lights are flashed on and the observer is told which one of the three levers is to be pulled for each of the five lights One of the pedals is to be pressed with the sound of one of the rattles The man taking the test is told that after an unspecified period every error will be counted against him The stimuli are presented in a pre-determinert random order in 10 series of 30 each During an intermission of two minutes the order is changed after which another 10-series is presented The test of 600 visual-auditory stimuli takes 20 minutes All responses and reaction times are recorded automatically During the test the subject is observed from behind a screen and the observations noted in detail Command Tests In another type of reaction test sometimes used four sticks are suspended by a magnet As they are released a bell a rattle or a horn is sounded Four candidates are examined simultaneously Each is required to hold a stick loosely with

automatically In the field for which he is heat command of combat troops supply service mechanical supervision etc It reveals not only his ability but his character and personality The test Is administered by an organization in which at the outbreak of the war about 200 psychologists all doctors of philosophy were employed It probably Iihs been much enlarged since These doctors are not officers but They are under the command of a sinister figure named Max Simnneit dean of German military psychology who has contributed largely to methods of propaganda and the planting of psychologists in other rountries to study the character of the people and determine methods whereby their minds can best te manipulated thus constituting the pioneers of "fifth Methods Are Described Many of the methods used by Simoncit and his colleagues are In the files of the United States Army and Navy Thpy have been garnered by a prominent American psychologist from various sources including German psychological publications issued shortly before the war which passed unnoticed in the rest of the world The long examination to which the prosjiective officers submit themselves is an attempt to measure five things according to these records: general intelligence willpower ability to command expressive movements and total personality The candidate is examined by a board consisting of two officers one physician and three psychologists the latter showing the importance attached bv the general staff to not getting pegs in round Most of the tests are administered individually but others arc given to croups of five The candidate does not get a score but the report of the psychologists largely subjective usually determines his fate The Intelligence Test First comes the intelligence test which bears little relationship to those given in American schools The prospective officer Is allowed to study a complicated picture for a few seconds and then is asked to describe it with as
