When Channel row, in which he had lived for some
years, was ordered to be taken down to make way for the
new bridge at Westminster, Dr. Desaguliers removed to
lodgings over the Great Piazza in Covent Garden, where
he carried on his lectures till his death. He is said to
have been repeatedly consulted by parliament, upon the
design of building that bridge; in the execution of which,
Mr. Charles Labelye, who had been many years his assistant, was appointed a supervisor. He likewise erected
a ventilator, at the desire of parliament, in a room over the
house of commons. In 1742 he published a “Dissertation on Electricity,
” by which he gained the prize of the
academy at Bourdeaux. “This prize,
” Dr. Priestley observes, “was a medal of the value of 300 livres, proposed,
at the request of monsieur Harpez de la Force, for the
best essay on electricity; and shews how much this
subject engaged the attention of philosophers at that time.
The dissertation is well drawn up, and comprizes all that
was known of the subject till that period.
” Dr. Desaguliers, who is styled by Dr. Priestley “an indefatigable
experimental philosopher,
” died Feb. 29, 1744, at the
Bedford coffee-honse, Covent Garden, where he had lodgings, and was buried March Cth, in the Savoy. He was
the first who introduced the reading of lectures in experimental philosophy at the metropolis; and was a member
of several foreign academies, and corresponding member
of the royal academy of sciences at Paris. His personal
figure was not very promising; for he was thick and short,
not well-shaped, his features irregular, and extremely nearsighted. In the former part of his life he lived very abstemiously; but in his latter years was censured for an
indulgence in eating to excess, both in the quantity and
quality of his diet. He translated into English, from the
Latin, Gravesande’s “Mathematical Elements of Natural
Philosophy.
” This work was published by his son J. T.
Desaguliers, in two volumes, 4to. He left two other sons:
Alexander, who was bred to the church, and had a living
in Norfolk, where he died in 1751; and another, named
Thomas, who became colonel of the royal regiment of artillery, and equerry to his present majesty, and rose to
the rank of major-general.

, a most illustrious prelate, and as he has been justly styled by Dr. Johnson, the great luminary of the Irish church, was descended from a very antient family, and born at Dublin, Jan. 4, 1580. His father, Arnold Usher, was one of the six clerks in chancery, a gentleman of good estate and reputation, and descended of a very ancient family, which in England bore the name of Nevil, till the reign of Henry II. when it was fchanged by one of his ancestors, who about 1185, passing with prince (afterwards king) John in quality of usher into Ireland, settled there by the name of his office, a practice very common in those early ages, and probably occasioned by the ambition of founding a family; and his descendants, spreading into several branches, filled the most considerable posts in and about Dublin for many ages, to the time of our author, who gave fresh lustre to the family. His mother was the daughter of James Stanyhurst (father of Richard the poet. See Stanyhurst) thrice speaker of the House of Commons, recorder of the city of Dublin, and one of the masters in chancery. This gentleman, of whom we took some notice in our account of his son, is yet more memorable for having first moved queen Elizabeth to found and endow a college and university at Dublin; in which he was vigorously seconded by Henry Usher , archbishop of Armagh, who was James Usher’s uncle. James discovered great parts and a strong passion for books from his infancy; and this remarkable circumstance attended the beginning of his literary pursuits, that he was taught to read by two aunts, who had been blind from their cradle, but had amazing memories, and could repeat most part of the Bible with readiness and accuracy; C<ecorum mens oculatissima. At eight years of age he was sent to a school, which was opened by Mr. James Fullerton and Mr. James Hamilton, two young Scots gentlemen, who were placed at Dublin by king James I. then only king of Scotland, to keep a correspondence with the protestant nobility and gentry there, in order to secure an interest in that kingdom, in the event of queen Elizabeth’s death: but her majesty being very sore upon this point, and unwilling to think of a successor, this was a service of some danger, and therefore it was thought expedient for them to assume the disguise of school-masters, a class of men which was very much wanted in Ireland at that time. Mr. Fullerton was afterwards knighted, and of the bed-chamber to king James; and Mr. Hamilton was created viscount Clandebois.
