of the angle Q D M=B A M," r or as the original before 

 me has it ' Q P N=B A M,' those angles being equal, the 

 result will be the same. 



Surely, Mr. Editor, such sweeping censure for typogra- 

 phical errors not affecting the solution, might have been 

 spared by one anxious to promote the circulation of 

 knowledge ; and as I affirm, having proved it, that they 

 in no way " make sad confusion," this phrase of the fanci- 

 ed Mathematician's might have been softened. The very 

 fact of the line A C not being drawn in the figure, ought to 

 have led a very superficial reader even, to correct the prin- 

 ter's mistake before alluded to. But I now proceed to notice 

 the " would-be Mathematician's" remarks on Solution the 

 First. But, en passant, I must observe that, as I gave the 

 avowed author's name, I do not feel myself bound to enter 

 into any controversy for his defence, though I think I may 

 very safely do it on the present occasion. Permit me also to 

 notice in this place, as we are harping on that string, that for 

 our future harmony it would be better if the words " 2d so- 

 lution" came in their proper place, opposite the para, imme- 

 diately above where they now appear, and " By the Rev. 

 J. Harker" at the close of the sentence immediately pre- 

 ceding — G H should also have been printed g H with a 

 little g — (though any tyro would have noticed this, and it 

 creates no confusion.) 



Having thus corrected the press, I venture to press the 

 following on your notice, in the hope that our friend will cor- 

 rect his hasty reckoning, and that he will prop up the Journal 

 with more proper contributions than the last. I love gentle- 

 manly discussions, am alive to their value, will always yield 

 with acknowledgment to proof and reason ; and the " would- 

 be Mathematician" shall find that, though " A Miner," when 

 the * blow up' is over I am, like a " good crater," open to as- 

 sault. I shall be glad to hear what he has to say against the 

 convincing proof of No. 2, which 



" Shows by lines and tangents straight 

 " What is small and what is great."
