During his protracted exile in England, De Lolme made a careful study of the English constitution, the results of which he published in his "Constitution de l'Angleterre" ("The Constitution of England", Amsterdam, 1771), of which an enlarged and improved edition in English appeared in 1775, and was several times reprinted. The work excited much interest as containing many acute observations on the causes of the excellence of the English constitution as compared with those of other countries. However, it was termed by the 11th edition of the "Encyclopædia Britannica" (1911) as "wanting in breadth of view, being written before the period when constitutional questions were treated in a scientific manner".
