George Saintsbury 
A History of English Prose Rhythm (Barnes & Noble Digital Library) [EPUB ebook] 

Published in 1912, this scholarly exploration of meter and rhythm begins with ancient Greece and Rome; moving through Old and Middle English; Chaucer; the ornate and plain styles; Edmund Burke; the great novelists of the nineteenth century such as Austen, Dickens, and Thackeray; the lyrical prose of John Ruskin; and more. It is one of the very few full-length studies of prose rhythm.
