One of the most important early works on electricity, containing a description of the FIRST ELECTRICAL MACHINE 

 WITH A GLASS CYLINDER (invented by the author), which was ' turned by a winch and rubbed by the hand ' , as well as 

 descriptions and illustrations of an improved air-pump of his invention, founded on his discovery of the 'lateral 

 communication of motion in air.' 



In his preface he mentions that ' the Nature and Laws of Electrical Attractions have not yet been much consider'd by 

 Any*. In the above work and his contributions to the Royal Society he carried further the tentative observations of 

 Dr. Gilbert and Boyle on electricity, and by his experiments may be said to have laid the foundation of that science. He 

 certainly was the first to discover the electric spark. He also determined the relative weight of water and air, and 

 ascertained the refractive index of various fluids. 



The above second edition contains a Supplement (pp. 86) of 24 new experiments, which is not contained in the edition 

 of 1709.
