I just found that my 3xg-grandfather, David Maynard, was a contributor to a book entitled:
Retrospect of philosophical, mechanical, chemical, and agricultural discoveries; being an abridgment of the periodical and other publications, English and foreign, relative to arts, chemistry, manufactures, agriculture and natural philosophy; accompanied, occasionally, with remarks on the merits or defects of the respective papers; and in some cases, shewing to what other useful purposes inventions may be directed, and discoveries extended, beyond the original views of their authors.
Vol. VI.
