ROLL OF HONOUR 147 Of the astronomers of modern times few have attained the eminence of John Couch Adams, the discoverer of the planet Neptune, who was born at Laneast in 1819. As a shepherd boy he loved to lie on his back and watch the stars, and he at once devoted himself to the study of astronomy when he was sent to school at Saltash. He became Senior Wrangler at Cambridge in 1843, and soon after taking his degree, being struck with irregularities in the motion of Uranus, he made a series of calculations and observations which resulted in the discovery of the new planet, the French astronomer Leverrier having simultaneously recorded its existence. A distinguished geologist and one of the pioneers of scientific cave exploration was William Pengelly, whose great work was the thorough examination of Kent's Cavern near Torquay, a labour which lasted from 1865 to 1880. Last, but by no means least worthy of mention in our list, must come Davies Gilbert, a great discerner of rising genius, to which he was ever ready to lend help and encouragement. The patron of Davy, Trevithick, Horn- blower, and Goldsworthy Gurney, he was himself a man of remarkable and varied abilities, scientist, mathematician, and antiquary, and President of the Royal Society. He died in 1839. 10 2
