57'. By this time Challis had recorded, without reduction, the
observations of 3,150 stars, as a commencement for his search. On
reducing these, he found a star, observed on August 12th, which was
not in the same place on July 30th. This was the planet, and he had
also observed it on August 4th.

The feeling of wonder, admiration, and enthusiasm aroused by this
intellectual triumph was overwhelming. In the world of astronomy
reminders are met every day of the terrible limitations of human
reasoning powers; and every success that enables the mind's eye to see
a little more clearly the meaning of things has always been heartily
welcomed by those who have themselves been engaged in like
researches. But, since the publication of the _Principia_, in 1687,
there is probably no analytical success which has raised among
astronomers such a feeling of admiration and gratitude as when Adams
and Le Verrier showed the inequalities in Uranus's motion to mean that
an unknown planet was in a certain place in the heavens, where it was
found.

At the time there was an unpleasant display of international jealousy.
The British people thought that the earlier date of Adams's work, and
of the observation by Challis, entitled him to at least an equal share
of credit with Le Verrier. The French, on the other hand, who, on the
announcement of the discovery by Galle, glowed with pride in the new
proof of the great powers of their astronomer, Le Verrier, whose life
had a long record of successes in calculation, were incredulous on
being told that it had all been already done by a young man whom they
had never heard of.

These displays of jealousy have long since passed away, and there is
