Live and act

Both the place of birth and the year of birth are not precisely determined, however the extensive research by Donald, F. Proctor suggests the following data; Mayow was born near Morval in Cornwall in 1641 . He was the second son of Phillip Mayowe (approx. 1600–1679) and his wife Frances Stukley, who had been married since November 22, 1635. He entered Wadham College , Oxford at the age of seventeen in 1658 . In 1660 he received a scholarship to The College of All Souls of the Faithful Departed at Oxford. There in Oxford he first studied law and graduated in 1665 with a bachelor's degree, bachelor of common law . Then followed the study of medicine, which he finished in 1670. He practiced as a doctor from 1670 to 1679 in the city of Bath in the summer and in London in the autumn and winter. In 1678 he was elected a member of the Royal Society on the proposal of Robert Hooke .

He died in London and was buried in St. Paul's Church in Covent Garden .

In his dissertation in 1669 he gave explanations for breathing and for combustion processes. After receiving his doctorate in 1670, he worked as a doctor and naturalist. He was of the opinion that air consists of two parts, one part of which is necessary for breathing to be alive. Mayow differentiated first between two qualitatively different proportions of the air, the proportion was essential need for creating an appearance of flame or combustion he called "Salpeterluft" or "fire air" or spirit nitro-Aereus (or spiritus vitalis ) because it in saltpetre as whose active or fiery component would appear (but in this it had a forerunner in Ralph Bathurst in Oxford 1654). This spiritus nitro-aëreus should enable combustion, be important for breathing and be a component of acids . In 1674 he described the formation of metal limestone as a union of metals with "saltpeter air", the spiritus nitro-aëreus .
