[Ads-l] Source(s) on history of alveolar tap/flap in English dialects?

[Neal Whitman]

Update: 
Oswald, Victor A. Jr. 1943. "'Voiced T': A misnomer." American Speech, 18(1), 18-25.

He cites a few earlier sources, who agree that /t/ has a "voiced t" allophone, but only one seems to realize it might also be happening with /d/ as well, which is what Oswald had been noticing. Oswald does an experiment that today would be criticized for some uncontrolled conditions, and for not sufficiently disguising the variables in question, but which still gets some persuasive results.

He does not use the IPA symbol for the alveolar tap, although according to Wikipedia, it was added in the 1930s.

Question now: When was AmE tapping of /t/ first noticed? Earliest cite in this paper is Bloomfield (1933). I've searched Google Books for strings like "Americans (mis)pronounce" in the 1800s. Interesting hits, but no pay dirt yet.
