“ Although Clark was before all a classical scholar, he published little in that branch of learning. A contemplated edition of the works of Aristophanes, a task for which he was singularly fitted, was never published. ”

“ The work by which he is best known is the Cambridge Shakespeare (1863–1866) , containing a collation of early editions and selected emendations, edited by him at first with John Glover and afterwards with W. Aldis Wright. Gazpacho (1853) gives an account of his tour in Spain; his visits to Italy at the time of Garibaldi’s insurrection, and to Poland during the insurrection of 1863, are described in Vacation Tourists, ed. F. Galton, i. and iii.
H. A. J. Munro in Journal of Philology (viii. 1879) describes Clark as “the most accomplished and versatile man he ever met” ”
