In 1699, John Woodward published his water-culture experiments with spearmint. He found that plants in less pure water sources grew better than plants in distilled water. While still a student, he became interested in botany and natural history, and his attention during visits to Gloucestershire was drawn to the fossils found there. He began to form the great collection, for which he is known. He published An Essay toward a Natural History of the Earth and Terrestrial Bodies, especially Minerals, &c. in 1695, followed by Brief Instructions for making Observations in all Parts of the World. He later wrote An Attempt towards a Natural History of the Fossils of England. In these works he showed that the stony surface of the earth was divided into strata, and that the enclosed fossils were originally generated at sea; but his views on the method of rock formation remained unsupported. They were satirized by John Arbuthnot, who ridiculed what he saw as Woodward's classicist method and personal venality. Nonetheless, Woodward accurately described his rocks, minerals and fossils in his elaborate Catalogue. Woodward's The State of Physick and of Diseases... Particularly of the Smallpox arose from a long-running dispute over smallpox with John Freind. Both accused the other of killing their patients. Woodward claimed that his experimental evidence showed that smallpox arose from an excess of "bilious salts", whereas Freind saw the causes of the disease as unknowable.
A notable shield bought by John Conyers from a London ironmonger was sold to Woodward after his death by one of his daughters. The shield, now in the British Museum, is recognised as a classicising French Renaissancebuckler of the mid-16th century, perhaps sold from the Royal Armouries of Charles II, but thought by Woodward and others to be Roman. Woodward published a treatise on it in 1713, provoking a satire on the "follies of antiquarianism" by Alexander Pope, written in the same year, but not printed until 1733. Woodward is mentioned twice in Pope's Fourth Satire of Dr. John Donne and is a candidate for the original of "Mummius" in Pope's The Dunciad.
Bequest
Woodward's will directed that his personal estate and effects be sold, and land to the yearly value of £150 purchased and conveyed to the University of Cambridge. A lecturer was to be chosen and paid £100 a year to read at least four lectures a year on a subject treated in his Natural History of the Earth. This created the Woodwardian professorship of geology. He also bequeathed his collection of English fossils to the university, to be under the care of the geology lecturer. This formed the nucleus of the Cambridge Woodwardian Museum, whose specimens have since been moved to the Sedgwick Museum of Earth Sciences.
