Among the other Italians whom Holbach befriended were Paulo Frizi,
the mathematician; Dr. Gatti; Pincini, the musician; and Mme. Riccoboni,
ex-actress and novelist; whose lively correspondence with Garrick
whom she met at Holbach's sheds much light on the social relations of
the century.

Among the other foreigners who were friends or acquaintances of Holbach
were his fellow countrymen, Frederich Melchon Grimm, like himself a
naturalized Frenchman and the bosom friend of Diderot; Meister, his
collaborator in the _Literary Correspondence_; Kohant, a Bohemian
musician, composer, of the _Bergere des Alpes_ and Mme. Holbach's
lute-teacher; Baron Gleichen, Comte de Creutz, Danish and Scandinavian
diplomats; and a number of German nobles; the hereditary princes of
Brunswick and Saxe Gotha, Baron Alaberg, afterwards elector of Mayence,
Baron Schomberg and Baron Studitz.

Among the well known women of the century Holbach was most intimate
with Mme. d'Epinay, who became a very good friend of Mme. Holbach's
and was present at the birth of her first son, and, in her will, left
her a portrait by Rembrandt. He was also a friend of Mme. Geoffrin,
attended her salon, and knew Mlle. de Lespinasse, Mme. Houderot and
most of the important women of the day.

who had lived on terms of the greatest intimacy with him for
twenty-four years, wrote a long eulogy which filled the issue of
the _Journal de Paris_ for Feb. 9. There was another letter to
the _Journal_ on Feb. 12. Grimm's _Correspondance Litteraire_ for
