Query: good book with thick notes

The book arrived sooner than I expected. Although the delivery of amazon was as bad as before and the cover pages of book was broken by the turbulence of delivery as before, the first touch of the book still gives me comfort.the book begins with a long preface, and two pages of chronology. The content was about 2/3 of book, and the rest 1/3 was the note. I am familiar with author's name Bacon, and I have recited the essay 51, of study, but I never expected such a long note at the end of the book. It indeed need such a long list of note. The English author used was not modern and the grammar was strange, let alone the anecdotes and jargon.It is a good book, and it costs time to comprehend it, and it worth the time.
