A reminder in case some of you are unaware of it...

I made Hamilton's exposition (and small correction) of Abel's proof
available on the Web some time ago. The URL for Hamilton's paper

On the Argument of Abel, respecting the Impossibility of
expressing a Root of any General Equation above the Fourth
Degree, by any finite Combination of Radicals and Rational
Functions.

is

I am very grateful for notification of any typographical or other
errors that people notice in the material available from this site.

The above paper is included in an expanding collection of resources
relating to Sir William Rowan Hamilton that I am building up at

http://www.maths.tcd.ie/pub/HistMath/People/Hamilton/

(I have already made available the text of about thirty of
Hamilton's mathematical papers, and in recent months have been
preparing for release on the Web some of Hamilton's more
substantial papers on quaternions, including the quaternion
papers in the Philsophical Magazine, further papers on the Theory
of Equations (with his refutation of Badano's supposed method of
solving quintic equations by radicals), and also his paper on
'Algebraic Couples', with the 'Essay on Algebra as the Science of
Pure Time'. I hope to release this on the Web in the coming
months.)

(I would also like to make Abel's original paper on the quintic
available some time in the future, when I can find the time to type
it up.)

Yours,
