"M. de Bordeu, in his "Recherches sur les Maladies Chroniques,"... makes so honourable mention of John Rey, that we invite the curious to have recourse to it.—M. Jean Frederick Corvin sustained a thesis, entitled Historia aëris factitii, under the presidency of M. Spielman, at Strasbourg, on the 4th of December, 1776, a pamphlet of sixty pages... with figures in which John Rey is named as the first author, who has written on this important subject. The elements of chemistry for the public course of the academy of , of this year, may also be consulted. M. Sage praises it in his Mineralogie Docimatique, lately reprinted. Finally, M. Bayen, a celebrated chemist, was the first to do justice to John Rey, and he has permitted his Letter to M. L'Abbé Rozier to be printed at the beginning of this edition."
