This entitles the name of Barnard to be inscribed on the same select roll as that which contains the name of Asaph Hall.

On such an occasion astronomers of all countries freely offer their hearty congratulations to those who pursue their science in America. In no other country can there be found such a lavish and splendid endowment of astronomical observatories. Nowhere else is there such abundant provision for the carrying on of astronomical work of all kinds. It were fitting that the rewards should go to the credit of the country which has done most to earn them. There is no civilised nation whose inhabitants would not have experienced a thrill of pride if such a discovery as that of the two moons of Mars or of the fifth satellite of Jupiter had been achieved within its borders by one of its own people. As it happens, both these distinctions belong to America, and those who are fully acquainted with the matter know how valiantly the American astronomers have struggled with their difficulties and how
