After this great discovery, for which he received the Copley medal of the Royal Society, Mr. Dollond devoted himself to the improvement of the achromatic telescope, in conjunction with his other pursuits. We are informed by G. Dollond, Esq., that his grandfather, at the latter end of his life, was engaged in calculating almanacs for various parts of the world; one of which, for the meridian of Barbadoes, and the year 1761, is now in his possession.
Mr. Dollond was elected a fellow of the Royal Society in 1761. In the same year, November 30, he was struck with apoplexy, while attentively engaged in reading Clairaut’s Theory of the Moon, which had then just appeared. He died in a few hours afterwards, in the fifty-sixth year of his age. His son Peter Dollond, already mentioned, continued the business in partnership with a younger brother; and it is now most ably carried on by his daughter’s son, who has, by permission, assumed the name of Dollond.
The following extract is from the memoir written by Dr. Kelly, in which we find nothing to regret, except that so few traits of character are related in it. Those who write memoirs of remarkable men from personal knowledge, should remember that details of their habits and conversation will be much more valuable to posterity, than disquisitions upon their scientific labours and discussions, which, coming from the pens of friends or relations, will always be looked upon as _ex parte_ statements. Had the learned author borne this in mind, we should have been able to give a better personal account of Dollond than the following; which is absolutely the only information relative to his private character which we can now obtain. “He was not content with private devotion, as he was always an advocate for social worship; and with his family regularly attended the public service of the French Protestant church, and occasionally heard Benson and Lardner, whom he respected as men, and admired as preachers. In his appearance he was grave, and the strong lines of his face were marked with deep thought and reflection; but in his intercourse with his family and friends he was cheerful and affectionate; and his language and sentiments are distinctly recollected as always making a strong impression on the minds of those with whom he conversed. His memory was extraordinarily retentive, and amidst the variety of his reading he could recollect and quote the most important passages of every book which he had at any time perused.”
