The first part consists of four letters, the last on ' Observations and Suppositions towards forming a new Hypothesis, 

 for explaining the several Pha*nomena of Thunder Gusts', with Additional Papers by Peter Collinson. 



The second and third part contain thirteen additional letters, also ' Remarks on the Abb6 NoUet's Letters on 

 Electricity to Benj. Franklin, by David Coldkn, of New-York,' and ' Electrical Experiments, with an attempt to account 

 for their several Phtenomena; with some Observations on Thunder-Clouds, by John Canton, f.r.s.' the last passage 

 reading : ' Is not the aurora boreolis the flashing of electrical fire from positive towards negative clouds at a great distance, 

 through the upper part of the atmosphere, where the resistance is least?' 



The work .started a new era in electrical science, and contains a number of valuable experiments and suggestions, e.g.. 

 his 'one-fluid theory ' of electricity and the ' Franklin Plate,' explaining the theory of the Leyden Jar, the discovery of 

 the electric action of points, which resulted in his invention of the lightning rod, etc. etc. etc. 



'They were not originally designed for publication, but Collinson thought them too important to be withheld. The 

 public interest in these experiments justified CoUinson's anticipations. 'Nothing,' says Priestley, ' ever written on the 

 subject was mere justly applauded. All the world, even kings, flocked to see them, and retired full of admiration '.'
