From A Compendium of Irish Biography, 1878
Johnstone, Charles, author of Chrysal or the Adventures of a Guinea, was born at Carrigogunnel, County of Limerick, about 1719. He was called to the Bar, but deafness prevented him from practising otherwise than as a chamber counsel. His Chrysal attracted much attention at the time, revealing as it did the secret springs of some current politics, and exposing the profligacy of several men of rank. Amongst other works he wrote the Reverie. In 1782 he sailed for India, where he became the proprietor of a newspaper, and having acquired considerable property, died in Calcutta about 1800.
