Grammar, Usage / Quoting a quotation cited on a page of website [2]

I am new to using the MLA format, and I need help with this seemingly complicated in-text citation and how to list it in the Works Cited section. Both quotations are taken from the site: melville.org/ with the main page titled "The Life and Works of Herman Melville". However, the quotes are in the section "Contemporary Criticism and Reviews"on another page titled "Moby-Dick; or, The Whale". This is how I did and it would be nice if you can tell me if I totally messed it up:

While some highly regarded critics like Henry F. Chorley wrote in London Athenaeum on October 25, 1851 that the book: "is an ill-compounded mixture of romance ... and obscurely managed." (qtd. in Contemporary Criticism), others, writing in the journal London Britannia, on November 8th, 1851, saw some merit in the "eccentric" elements stating that: "The Whale is a most extraordinary work. (qtd. in Contemporary Criticism).

And here is what I wrote in Works Cited:

"Cotemporary Criticism." The Life and Works of Herman Melville 25th July, 200. Web viewed 25th May 2011. <melville/hmmoby.htm#Contemporary>

Please let me know if it needs fixing.
Thanks in advance.
