FIRST EDITION.  In his introduction, Louis Le Vasseur describes the three articles, and explains their inclusion in the work. Grew's article, originally published in English, has been translated to French of the importance of his experiments. Boyle's treatise includes information on 24 experiments, 12 dealing with flavors, and 12 dealing with odors.  Le Vasseur explains that he decided to include Leeuwenhoek's article because his experiments and observations on blood and milk are worthy of the curiosity of scholars. The treatise by Leeuwenhoek contains five articles written between April 1674 and February 1678, providing observations for experiments conducted in April, June and July 1674, August 1675, and February 1678. The fifth article, apparently unrecorded in Dobell, may be published here for the first time. In these articles, Leeuwenhoek describes in particular the deformability and agglutination of red blood cells.  RARE: according to online records, only two copies of this work have sold at auction in the last 45 years.
