Gyllenberg's Natural and Chemical Elements of Agriculture; in 1772 an Essay on the Weather (translated into Dutch in 1772), and Essays, Moral, Philosophical, and Political (anonymous, but advertised under his name); and in 1776 a Treatise on Cattle. On 13 February 1766 Mills was elected a Fellow of the Royal Society with Benjamin Franklin as one of his sponsors. He was the first foreign associate of the French Agricultural Society, on whose list his name, with London as his residence, appears from 1767 to 1784. He was also member of the Royal Societies of Agriculture of Rouen, the Mannheim Academy of Sciences, and the Economical Society of Bern. Work John Mills was credited for his comprehensive knowledge of agriculture, and of the cultivation and use of the ground. He authored and translated several works in these fields. He became a well known author on the subject of husbandry in the 1760s, and was elected member of the Royal Society in 1766. He had come to prominence about twenty years earlier, while working on the translation of Chambers's Cyclopaedia. Encyclopédie Ephraim Chambers had first published his Cyclopaedia, or an Universal Dictionary of Arts and Sciences in two volumes in London in 1728, following several dictionaries of arts and sciences that had emerged in Europe since the late 17th century. This work became quite renowned, and four editions were published between 1738 and 1742. An Italian translation of this work appeared from 1747 to 1754. In France a member of the banking family Lambert began translating Chambers into French, but in 1745 John Mills and Gottfried Sellius were the first to actually prepare a French edition of Ephraim Chambers's Cyclopaedia for publication, which they entitled Encyclopédie. Early in 1745 Mills and Sellius published a prospectus for the Encyclopédie to attract subscribers to the project. This four-page prospectus was illustrated by Jean-Michel Papillon, and accompanied by a plan (see image), stating that the work would be published in five volumes from June 1746 until the end of 1748. The text was translated by Mills and Sellius, and it was corrected by an unnamed person, who appears to have been Denis Diderot. The prospectus was reviewed quite positively and cited at some length in several journals. The Mémoires pour l'histoire des
