George Sand describes it as "un peu exuberant de style, mais rempli de bonnes choses et de tres-belles pages." These words, however, do in no way justice to the book: for, on the one hand, the style is excessively, and not merely a little, exuberant; and, on the other hand, the "good things" and "beautiful pages" amount to a psychological study of Chopin, and an aesthetical study of his works, which it is impossible to over-estimate.
Still, the book is no biography.

It records few dates and events, and these few are for the most part incorrect.

When, in 1878, the second edition of F.Chopin was passing through the press, Liszt remarked to me:-- "I have been told that there are wrong dates and other mistakes in my book, and that the dates and facts are correctly given in Karasowski's biography of Chopin [which had in the meantime been published].

But, though I often thought of reading it, I have not yet done so.

I got my information from Paris friends on whom I believed I might depend.
