ARTIFICIAL SUN
 CUTSCOLDS DOWN
40 Per Cent Drop Observed at
 Cornell University

Ithaca, N. Y., Jan. 21 GP)-In corner room up under the raftcrs Of it's old armory, Cornell university this winter is making artificial sum- mer sunshine to help guard it's stu dents again st colds.
 Electrical apparatus makes the light in two kinds. one for boys an l the other for girls, offering for the first time to large numbers of stu dents method of mitigating coils tEat is based on three years of suc- ceAsful experimenting upon small, selected groups.
 Hundreds of students visit the place, for It requires only 10 to !6 minutes once q week to absorb th,s sunshine armor.
 During the mons hours the boys arrive about q dozen at lime un- der an allotted schedule. They dis ''robc and dress for the light in not much more than a pair of dark goG- Glcs to protect their eyes.
 Awaiting them is T room thai al q turn of q switch shinlmcrs in tH" glow from dozen mercury -rappr tubes, bluegrecn, solid shafts nr light. more than in inch in diam ater, each standing in vertical posi- i ton upon the floor and as tall as man.
 These lights arc placed around all sides and down the middle of i inc room. In front of each, foo prints painted on the bare floor 1 mark the proper distance 10 stand, ,: Inches away from the light The boys stand on these marks and at regular intervals shift 10 an- other light. thereby moving through a cycle that in lG minutes gives Il equal portion of direct rays 10 every part of the body An electric clock rings the time signals for shifting from one light t to another. The tubes radiate the rltra-violct light that causes tan, but the boys do no remain long enough to acquire even rcdncss In i this broyity of treatment appears 70 lie the secret of success of the Cor nell method.
 Ii is q technic worked out in ev- pcriments each winter since 19 35 l by Dr. George II. Vaughan and Dr. 1 Dean F. Smiley, head of the Cor nell health department. under q i grant from the Sage fund.
 Previously some light trca.- mcn,s elsewhere had indicated negative results for colds. Study ing these records, the Cornell scientists decided that possibly failures had been due 10 over x. posture and accordingly used q mild dosage
 They found that this mild use ot light twill in most instances reduce by at least 4o per cent the incl de""" of colds in cold susceptible individuals"
 In'y concluded also that it lis not q complete panacca for the pr,- Ncntion of colds" because lack Of ultra violet light is but one of sev- eral known factors in colds.
 All these preliminary eXpcr;- mcnis were made upon men, but Dr. Vaughan said there should he no difference in the effects of the 1 light upon women.
 But because the girls are moro subject 10 anemia. T different set Of lights was installed for thcn,. giving off inira-rcd, or heat rays, in addition 10 q high per cent of visible and the comparatively cold ultra violet.
 These combination rays are made by gre lights, in which the cartons contain special metals to intensity the health rays.
 The apparatus used in this win- . ter sun lrlor would cost about
 $2.50O. A small fee is charged stl. dents ia k ing he treatment
