EEEIiY TO PROF. VINCE. 



tlepty to Professor Vi Sice's Ultimatuin. By d Correspondent 



To. Mr. NICHOLSON. 



Sir, 



be aliowed as 

 in argument, 



JLT is no unusual expedient with an expert disputant, to 

 affect a contempt for his antagonist, which he does not feel j 

 and to decline a contest, to which he is unequal, on the 

 Silence not to pretence, that it is superfluous to engage in it. 1 anat 

 far from vihshing, to protract a controversy with Professor 

 Vince; but I protest against his right to excuse himself 

 from the necessity of replying to any future observations of 

 mine on the ground of his engagement not to trouble you 

 further on the subject. If however the Professor thinks ray 

 remarks undeserving of any additional notice from him~ 

 self, it is to be presumed, that some person will be found 

 among the numerous disciples of that illustrious school, in 

 •which he holds so distinguished a situation, who will un** 

 dertake the easy task of confuting rae, and vindicating the 

 honour of the university from the slightest shade, that the 

 publicity of such a mistake as I have imputed to Professor 

 Vince could possibly cast on it. 



I grant, that three quantities are *' put down" in the essay, 

 which the Professor now calls the first terms of three series: 

 but I still shall deny, that these series are to be found, or arc 

 any where mentioned, in that work. It is not a Kttle re- 

 markable, that a man, whose life is devoted to the science of 

 reasoning with accuracy, should adduce so weak a proof of 

 my being guilty of misrepresentation. 



With respect to the sufficiency of each of these quanti- 

 ties for determining its share of the force, Professor 

 Vince's words are, p. 19 : " Now the terms omitted in the 

 Quantities era- series are comparatively so extremely small, that if they 

 be°suffiSnt^° ^'^^^ "^* considered, they could make no sensible alteration 

 in the result," And now he accuses me of a second " un- 

 accountable misrepresentation," for saying, that he has men- 

 tioned 



Series not 

 mentioned.
