This volume (the 14th of a series of 19) contains 21 letters written between August 1701 and March 1704. At least half of these letters were addressed to Fellows of the Royal Society in London. Every volume in the series contains the texts in the original Dutch and an English translation. The great range of subjects studied by Van Leeuwenhoek is reflected in these letters: instruments to measure water; pulmonary diseases; experiments relating to the solution of gold and silver; salt crystals and grains of sand; botanical work, such as duckweed and germination of orange pips; descriptions on protozoa; blood; spermatozoa; and health and hygiene, for example and harmfulness of tea and coffee and the benefits of cleaning teeth.;Volumes One to 13 are available at a reduced price from Swets and Zeitlinger.

In volume XVI of The Collected Letters of Antoni van Leeuwenhoek, 25 letters of Van Leeuwenhoek have been included, all of them written from July 1707 to June 1712. The letters were written to six distinct addressees. The larger part was addressed to the Royal Society in London in general (sixteen letters); and to three of its fellows in particular

The twelfth of the 20-volume set compiled and annotated by the Royal Netherlands Academy of Sciences and Letters, contains 37 letters written between July 1696 and December 1699, during which time the Dutch naturalist resumed his correspondence with the Royal Society in London. Among the myriad topics he writes about are divining rods, liver flukes, analysis of a mineral from Sumatra, the hatching of snail eggs, the honey-dew produced by green flies, the cornea and eyes of a beetle, trachea of a gnat's brain, blood circulation in the tails of young eels and tadpoles, and his discovery of spermatozoa and reasoning that there must be male and female individuals. The book is bilingual throughout, including the short introduction, the biographical section, the list of Leeuwenhoek's measures, and index. The notes provide scientific philological, historical, and biographical information. Drawings are reproduced in eight pages of bandw plates. Annotation copyrighted by Book News, Inc., Portland, OR

The contents of the letters published here, again show the great range of subjects that occupied Van Leeuwenhoek: from sugar candy, the shape and crystal structure of diamonds, the dissolution of silver crystals in aqua fortis to gold dust from Guinea dissolved in aqua regia and the dissolution and separation of gold, silver, and copper.
