Between 1713 and 1721 he acted as secretary to the Royal Society, and early in 1720 he succeeded Flamsteed as astronomer-royal.
Flamsteed gives an interesting account of his travels in Ireland.
It is evident that by this time Flamsteed's interest in all astronomical matters had greatly increased.
As the places of the stars were known, Flamsteed was thus able to obtain the places of the planets.
And no doubt Flamsteed's observations, twenty or thirty of them at least, were of signal use.
Flamsteed was indeed glad to avail himself of this opportunity.
Flamsteed enlarged these catalogues to the number of about 3,000.
Born on October 29, 1656, he was ten years the junior of Flamsteed.
This led to, perhaps, the most painful scene in the lives either of Newton or Flamsteed.
It is very common in our modern catalogues to give both the Bayer letter and the Flamsteed number in the case of Bayer stars.
