The specific page is accessible without institutional
privilege. Better, some search facilities at
http://portal.acm.org are freely accessible and lead to the
above. But as expected, full text is not accessible.

     Additionally, my notes reveal that a couple of years
ago, I encountered a 1928 reference to an ambitious
orthogonal classification of *implicit* cubic loci:

==> Burington, R. S. and Holt, H. K. ``Canonical forms of
plane cubic curves under euclidean transformations'',
Annals of Math., 30(1928),  51-60.

But I do not recall ever laying my hands on the article,
and even its existence slipped my mind.
