A beautifully illustrated work on the microscope and its uses. One of several works by Baker on the microscope. J. Cuf (John Cuff) was an optician who worked from 1731-1771 and was recognized for making significant contributions to the evolution of the microscope. Henry Baker was a patron of Cuff, lending him money on more than one occasion.
The previous owner Barnett Cohen worked worked professionally as a bacteriologist, conducting the first ultra-microscopic surgeries. He was also an enthusiast of and published several articles on Leeuwenhoek (Antonie Philips van Leeuwenhoek FRS was a Dutch microbiologist and microscopist in the Golden Age of Dutch science and technology. A largely self-taught man in science, he is commonly known as "the Father of Microbiology", and one of the first microscopists and microbiologists. - Wikipedia)
The first edition of this title was published in 1742. This second edition and subsequent editions had the extra folding plate of the solar microscope not present in the first edition.
