every line he wrote that he was one who could not brook anything like criticism or opposition. Such a man, however efficient, was little likely to be happy as the first incumbent of a new and important government post; but there was another circumstance which was destined to cause him greater unhappiness still. If we believe, as surely we must, that not only the moral and the physical progress of mankind is watched over and controlled by God's good Providence, but its intellectual progress as well, then there can be no doubt that John Flamsteed was raised up at this particular time, not merely to found Greenwich Observatory, and to assist the solution of the problem of the longitude at sea, but also, and chiefly, to become the auxiliary to a far greater mind, the journeyman to a true master-builder. But for the founding of Greenwich Observatory, and for John Flamsteed's observations made therein, the working out of Newton's grand theory of gravitation must have been hindered, and its acceptance by the men of science of his time immensely delayed. We cannot regard as accidental the combination, so fortunate for us, of Newton, the great world-genius, to work out the problem, of Flamsteed, the painstaking observer, to supply him with the materials for his work, and of the newly-founded institution, Greenwich Observatory, where Flamsteed was able to gather those materials together. This is the true debt that we owe to Flamsteed, that, little as he understood the position in which he had been placed from the standpoint from which we see it to-day, yet, to the extent of his ability, and as far as he conceived it in accordance with his duty, he gave Newton such assistance as he could. This is how we see the matter to-day. It wore a very different aspect in Flamsteed's eyes; and the two following documents, the one, the warrant founding the Observatory and making him Astronomer Royal; the other, the warrant granting him a salary, will go far to explain his position in the matter. He had a high-sounding, official position, which could not fail to impress him with a sense of importance; whilst his salary was so insufficient that he naturally regarded himself as absolute owner of his own work. _'Warrant for the Payment of Mr. Flamsteed's Salary._ 'Charles Rex.
