""Extracts From Micrographia"" is a book written by Robert Hooke in 1665, which provides a detailed description of the various microscopic organisms that he observed using magnifying glasses. The book is divided into various sections, each of which deals with a different category of minute bodies, including insects, plants, and animal tissues. Hooke's observations are accompanied by detailed illustrations, which provide a clear and accurate representation of the organisms he observed. In addition to describing the physical characteristics of these organisms, Hooke also poses various questions and inquiries about their behavior and function, which demonstrate his curiosity and scientific rigor. Overall, ""Extracts From Micrographia"" is a fascinating and groundbreaking work that provides an important insight into the early history of microscopy and the study of microscopic organisms.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

Robert Hooke FRS (/hʊk/; 28 July [O.S. 18 July] 1635 – 3 March 1703) was an English natural philosopher, architect and polymath.
His adult life comprised three distinct periods: as a scientific inquirer lacking money; achieving great wealth and standing through his reputation for hard work and scrupulous honesty following the great fire of 1666, but eventually becoming ill and party to jealous intellectual disputes. These issues may have contributed to his relative historical obscurity.
He was at one time simultaneously the curator of experiments of the Royal Society and a member of its council, Gresham Professor of Geometry and a Surveyor to the City of London after the Great Fire of London, in which capacity he appears to have performed more than half of all the surveys after the fire. He was also an important architect of his time – though few of his buildings now survive and some of those are generally misattributed – and was instrumental in devising a set of planning controls for London whose influence remains today. Allan Chapman has characterised him as "England's Leonardo".
Robert Gunther's Early Science in Oxford, a history of science in Oxford during the Protectorate, Restoration and Age of Enlightenment, devotes five of its fourteen volumes to Hooke.
Hooke studied at Wadham College during the Protectorate where he became one of a tightly knit group of ardent Royalists led by John Wilkins. Here he was employed as an assistant to Thomas Willis and to Robert Boyle, for whom he built the vacuum pumps used in Boyle's gas law experiments. He built some of the earliest Gregorian telescopes and observed the rotations of Mars and Jupiter. In 1665 he inspired the use of microscopes for scientific exploration with his book, Micrographia. Based on his microscopic observations of fossils, Hooke was an early proponent of biological evolution. He investigated the phenomenon of refraction, deducing the wave theory of light, and was the first to suggest that matter expands when heated and that air is made of small particles separated by relatively large distances. He performed pioneering work in the field of surveying and map-making and was involved in the work that led to the first modern plan-form map, though his plan for London on a grid system was rejected in favour of rebuilding along the existing routes. He also came near to an experimental proof that gravity follows an inverse square law, and hypothesised that such a relation governs the motions of the planets, an idea which was subsequently developed by Newton. Much of Hooke's scientific work was conducted in his capacity as curator of experiments of the Royal Society, a post he held from 1662, or as part of the household of Robert Boyle.
