3744 PRA.TT (Henry, M.D.) PRINCIPIA NOVA ASTRONOMICA, with 44 plates, 4to. cl. gilt (out of 

 print), Is Qd 1894 



Propounding a 'quaternary solar system', making the sun to revolve round an equatorial sun, the latter round a polar 

 sun, and that round the central sun, the centre of the universe. None of these suns are supposed to be luminous, and the 

 work is modestly prefaced by ' quis credet' ?

 JECTION, with 26 diagrams, large 8vo. cl. (SCARCE), 10s Qd 1862 



'Dr. Pratt not only upsets Newton, but cuts away the very ground he stands on : for he destroys the first law of 

 motion, and will not have the natural tendency of matter in motion to be rectilinear. This was also John Walsh's notion.' 

 Prof, de Morgan's Budget of Paradoxes. 



3746 On ORBITAL MOTION : the OUTLINES of a SYSTEM of PHYSICAL ASTRONOMY, diagrams, 



8vo. cl. (scarce), 10s Qd 1863 



' In this work Dr. Pratt insists that the precession of the equinoxes is caused by the motion of the solar system round a 

 distant central sun. In it the author refers to a few notes, which completely destroy the theory of gravitation in terms 

 'perfectly intelligible as well to the unlearned as to the learned ' : to me they are quite unintelligible, which rather tends 

 to confirm a notion 1 have long had, that I am neither one thing nor the other.' Idem.
