Second edition, greatly enlarged, of the first French book on microscopy (1st ed.: 1718 with the title Descriptions and only 34 plates). Joblot (1645-1723), professor of mathematics at the Ecole nationale des Beaux-Arts, probably became interested in microscopy during the visit of Huygens and Hartsoeker to Paris in 1678 when they demonstrated microscopes brought from Holland.

While Joblot’s observations were largely limited to protozoa in the first edition, the second edition reflects his study of minerals, plant cross-sections, and insects, illustrated on the plates in the first volume. The charming headpiece, repeated three times, depicts a scientist in his laboratory, surrounded by instruments, specimens, and books. The second volume contains a number of fine plates depicting many new kinds of microscopes and their construction.
