WALTER RATHBONE BACON TRAVELING SCHOLARSHIP 



The Walter Ratlibone Bacon scholarship, "for the study of the 

 fauna of countries other than the United States", was held during 

 1932 and 1933 by Dr. Alan Mozley, who conducted a study of the 

 molluscan fauna of Siberia. The scholarship was later extended to 

 cover 1934, and Dr. Mozley continued his investigations during the 

 past year, in the course of which he made a 3-months' journey through 

 the forest steppe to the south of Omsk. During the winter he worked 

 on his collections in Edinburgh. 



In the early summer of 1934 Dr. Mozley turned in a manuscript 

 describing the new mollusks discovered in the course of liis work, 

 and this paper will appear in the Smithsonian Miscellaneous Collec- 

 tions early in the next fiscal year. A full report on the fauna as a 

 whole will be made later, when Dr. Mozley has completed Ms studies. 



THIRD ARTHUR LECTURE 



In 1931 a bequest was received from James Arthur for the promo- 

 tion of a series of lectures at the Institution deaUng with various 

 aspects of the relation of the sun to the planets, the stars, the weather, 

 and human life. The third Arthur Lecture was given by Dr. Charles 

 G. Abbot, Secretary of the Institution, in the auditorium of the 

 National Museum on February 26, 1934, the subject being ''How 

 the Sun Warms the Earth." The speaker dealt with the sun as the 

 earth's source of heat, power, plant growth, and weather, and as a 

 type of the radiative features of the stars. The lecture Mdll be pub- 

 lished in the General Appendix to the 1933 Smithsonian Report, now

BEQUESTS 



Rollins bequest. — In the will of the late William Herbert Rollins, of 

 Boston, the Institution was named a beneficiary, and during the year 

 the sum of $58,580 was received under this bequest to establish a 

 fund to be known as "The Miriam and William Rollins Fund for 

 Exploration Beyond the Boundary of Knowledge." The conditions 

 of the trust are as follows: 



. . . the interest of the whole Miriam and William Rollins Fund is to be used 

 for five years to confirm my experiments on the drag of the light medium in the 

 magnetic field. After 5 years one half of the interest of the whole fund is to be 

 added each year to the Principal.
