sensions, those *••■ plus quam civilia bella," which degrade 

 the fields of science into an arena of contention ; — in order 

 to prevent, if possible, the continuance of such an evil, 

 as far as I am myself concerned, I have made an appeal 

 to the writer of the article in question, through the medium of 

 his friends, in the hope that, when the truth is laid before him, 

 he may of his own accord make due reparation for expres- 

 sions which I am fain to believe originated in some strange 

 and untoward misconception. 



This appeal has necessarily been attended with delay ; and 

 the time has already elapsed for making any satisfactory 

 statement in your present Number. In your next publication 

 I pledge myself to afford such an explanation, from whatever 

 quarter it may proceed, as, I trust, will be satisfactory to your 

 readers. 



In the mean time I have to thank you, my dear Sir, for 

 the kind sentiments you have expressed towards me on this 

 occasion. I required no assertions on your part to be con- 

 vinced that you were in no wise mixed up with the feelings 

 and spirit exhibited in the article referred to. No editor of 

 a periodical like yours, I am well aware, is responsible for 

 the sentiments contained in any paper to which the author 

 affixes his name. It has, indeed, been an extreme gratifi- 

 cation to me, sufficient, I may almost say, to counterbalance 

 the regret occasioned by this unexpected act of aggression, 

 to see so many of my friends rallying round me, and volun- 

 teering their warm-hearted sympathy in my cause. I can 

 well conceive how, to the high-toned feelings of the cavaliers 

 of older times, it was a source of exhilaration and triumph, 

 even beyond what they derived from the consciousness of 

 their own strength, to hear in the stress of war the generous 

 cheers of their companions in arms advancing "to the 

 rescue." I am, my dear Sir, 



Chester Terrace, very faithfully yours.
