5516 WRIGHT (Thomas, of Durham] An ORIGINAL THEORY, or NEW HYPOTHESIS of the UNI- 

 VERSE, founded on the Laws of Nature, and solving by MATHEMATICAL PRINCIPLES the GENERAL 

 PH/ENOMENA of the VISIBLE CREATION, and particularly the VIA LACTEA, with 32 fine plates 

 (on copper and in MEZZOTINT), 4to. old hf. calf (cracked, otherwise a very sound copy) ; RARE, 

 1. 1* 1750

' The first to form any definite idea as to the constitution of the stellar system was Thomas Wright, the son of a 

 carpenter living at Byer's Green, near Durham. With him originated what has been called the ' Grindstone Theory ' of 

 the universe, which regarded the Milky Way as the projection on the sphere of a stratum or disc of stars (our sun 

 occupying a position near the centre), similar in magnitude and distribution to the lucid orbs of the constellations ' 

 Miss A.M. Clerke. 



The work moreover contains the first definite suggestion that Saturn's ring consisted of a multitude of unconnected 

 particles, each revolving independently round the planet. J. Clerk Maxwell in 1857 demonstrated this as the only 

 scientifically tenable theory against the hypotheses of solid or fluid rings.

' The present volume forms an index to the state of general knowledge in England through upwards of five centuries. 

 In this point of view the Anglo-Saxon treatise on Astronomy [included above] is the most curious, because it is of so 

 remote an age as the tenth century.' Preface. 



This and Halliwell-Phillipps's ' Collection of Letters ' (v. No. 1756, ante) formed the only publications of the short- 

 lived ' Historical Society of Science '.
