C'est le Collège de Pharmacie de Paris qui confia à Rouelle et à Charlard le soin de déterminer si l'étain pouvait contenir des quantités d'arsenic succeptibles de rendre l'usage de vaisselle en étain dangereux pour la santé. Rouelle décéda avant le début de l'étude et fût remplacé par Bayen. Bayen est aujourd'hui reconnu comme étant un précurseur de Lavoisier. Il rejeta en effet la théorie du phlogistique 3 ans avant les travaux décisifs de ce dernier. Dans cet ouvrage sur l'étain, Bayen et Charlard conclurent que l'étain ne contenait pas d'arsenic, au pire des quantité infinitésimales, sans aucun danger pour la santé. L'avant propos contient une intéressante histoire sur l'étain.

Joints rubbed. Headcap worn, little loss of leather in the tail of the spine. Strong foxings on title page, waterstains on the first pages. First edition. Bayen is today recognized as a precursor of Lavoisier. He rejected the phlogistic theory 3 years before the decisive work of Lavoisier. In this book on the tin, Bayen and Charlard concluded that tin contained no arsenic at worst infinitesimal amount, without any danger to health.

8vo, pp. viii, 285. Contemporary blue boards, spine ruled in gilt (edges rubbed, tips of corners and head of spine slightly worn). FIRST EDITION. ?This government-ordered study was undertaken to determine whether tin from various sources contains arsenic in large enough amounts to make the use of vessels of tin harmful to health. Bayen and Charlard (Rouelle had been named to work with them but he died before the work began) repeated the experiments of Marggraf and added new ones. Their conclusion was that tin contained no arsenic or only minute harmless traces. In the course of the many experiments the nature and reactions of tin were examined in detail. The Avant-Propos contains a history of tin? (Cole). Bayen (1725?1798) was one of the first to doubt the phlogiston theory and performed noteworthy experiments on calcination; he is considered a forerunner of Lavoisier. Cole 64. DSB, I, pp. 529?530. Duveen, p. 54. Neville I, p. 101: ?A classic work?? Partington, III, pp. 394?399.
