Note 22 — INTRODUCTION
Reading edition
For these extracts I am indebted to the kindness of Dr. S. R. Gardiner, who has allowed me to use the transcripts of Barrière's correspondence with Condé, placed at his disposal by the Duc d'Aumale. The originals of the letters are preserved at Chantilly, and the copies quoted were made by M. Gustave Macon, the librarian and archivist of the Duc d'Aumale.
