Among the many important contributions to Astronomical Science by 
James C. Watson, one of the original members of the National Academy of 
Sciences, is the discovery of twenty-two minor planets commonly known 
as the Watson asteriods. The first of these, (79) Eurynome, was discovered

promoting astronomical research. One of the objects specifically designated 
was the construction of tables of the perturbations of the minor planets dis- 
covered by the testator. From the beginning Prof. Simon Newcomb was a
