The distinction and value of John Hopkinson's scientific work are so 

 evident and so universally acknowledged, that no attempt at appraise- 

 ment is required. His writings are terse enough to make careful 

 reading imperative, but there is no trace of ambiguity or vagueness. 

 They give an impression of easy mastery that is rare, even in work of 

 the first class. His attack on any subject is conspicuous for its direct- 

 ness and severe simplicity. Any preconceived ideas which might 

 impede it are brushed aside ; nothing is taken for granted, nothing is 

 slurred over. This indeed was a reflection of the nature of the man. 

 Straightforwardness, simplicity, intellectual honesty were of his very 

 essence. Admiration for his genius was not more universal than 

 respect for his peculiarly fine character, which, moreover, compelled 

 the warm affection of those who knew him best.
