"Bob Newton the landlord of the Ferrets Arms, Gas Works Lane, Bolton". Didn`t he do some works on the velocity/force ratio of real ale suspended at a height of 100m above sea level over the equator at 30 deg C at Noon GMT?

I had a quick look at the list of Fellows in the Royal Society's great tome, I can find Issac Newton but not Bob Newton. Surly this has to be a great injustice given his contribution to mankind.
