Establishment of fundamental rela- tions between light and life in recent Smithsonian Institution experiments was among the scientific achievements of the year reported to the annual meeting of the regents yesterday by Secretary Charles G. Abbot. These experiments dealt with the un- explained phenomenon of phototropism, or the bending of a plant toward the light. Dr. P. S. Brackett, in charge of the Division of Radiation and Organ- isms, found that blue light consisting of the wave lengths toward the short wave end of the visible spectrum has approximately 30,000 times the bending effect of yellow light, and that red light, consisting of longer wave lengths, has no effect at all that can be meas- ured. This indicates that “ an electronic change of energy” takes place in the plant under the influence of light, but that there is a threshold wave length beyond which light does not set off the mechanism in the plant cells, The bending effect first appears with yellow light, but is barely measurable. ~With green light, the next step upward toward the short end of the spectrum, it is increased 1,000 times. Blue light is 30 times more effective still, Theory Hitherto Held, Hitherto there has been a theory that phototropism was owing to accelerated growth due to extra heating of the side of the plant toward the sun. But, says Secretary Abbot’s report, this ex- periment “‘constitutes crucial evidence against any theory which seeks to ex- plain phototropism as a thermal effect due to unequal absorption of thermal energy. The rapid increase of effects as one proceeds to shorter wave lengths is typical of the photochemical reac- tions involving an electronic change of energy.” Study of the light- effects involved ‘work of extreme delicacy, since it was necessary to eliminate the effect of heating by getting the different colored hts of exactly the same intensity. e experiments were carried on with oat sprouts. The early work was vitiated by small temperature fluctuations in the air surrounding the sprouts. This was finally overcome by placing a dou- ble-wall cylindrical glass shield around each sprout,. filing the space between the double walls with water and keeping the cylinder in continual rotation. Thus, if one side was un- evenly heated, its influence would be carried around so as to be felt equally from ail sides. A second notable achievement of the Smithsonian, Dr. Abbot reported, is the discovery by the Astrophysical Ob- Santa Suggests These Unusual Dolls From Woodward & Lothrop’s Big 'Doll House For Good Little Girls 11.—A precious “Baby Dimples” doll that looks almost real.

The Smithsonian, Dr. Abbot an- nounced, has concluded its support of the experiments of Dr. R. H. Goddard of Clark University, who is trying to bulld a rocket to explore the unknown upper layers of the atmosphere and which is popularly known as “the moon FRIDAY, DECEMBER 12, 1930. by the Smithsonian for 12 years, and now has been taken over by the Gug- nheim Fund, enabling Goddard to gzntmue his work in New Mexico. teady in liquid g hydrocarbon Goddard, Dr. Abbet said, has automatic stabilizers and necessary automatic devices which “seemingly are all that is needed fllch: o first records of an unknown !
