Min. But perhaps the most curious of all is Mr. Willock's method: he treats the sides as radii of a circle, and the base as a chord.
Euc. He had better have made them asymptotes of a hyperbola at once! C'est magnifque, mais ce n'est pas la—Géometrie.
Min. Two of your Rivals prove Prop. 8 from Prop. 24.
Euc. 'Putting the cart before the horse,' in my humble opinion.
Min. For a brief proof of Prop. 13, let me commend to your notice Mr. Reynolds'—consisting of the seven words 'For they fill exactly the same space.'
Euc. Why so lengthy? The word 'exactly' is superfluous.
Min. Instead of your chain of Theorems, 18, 19, 20, several writers suggest 20, 19, 18, making 20 axiomatic.
Euc. That has been discussed already (p. 56).
Min. Mr. Cuthbertson's proof of Prop. 24 is, if I may venture to say so, more complete than yours. He constructs his diagram without considering the lengths of the sides, and then proves the 3 possible cases separately.
Euc. I think it an improvement.
Min. There are no other noticeable innovations, that have not been already discussed, except that Mr. Cuthbertson proves a good deal of Book II by a quasi-algebraical method, without exhibiting to the eye the actual Squares and Rectangle: while Mr. Reynolds does it by pure algebra.
Euc. I think the actual Squares, &c. most useful for beginners, making the Theorems more easy to understand and
