Notes on Chapter Two contain an error. Florentino Ariza is not the man with whom the girls held lotteries to hang out with, until he saw Fermina Daza; that was Dr. Juvenal Urbino. See the first paragraph in Chapter 3 to see where this sentence refers to the latter.
Actually, women held lotteries to hang out with both men. When Florentino is introduced in chapter 2 Marquez mentions this on page 54. Then again, on page 105 (the first page of chapter 3), the lotteries for Dr. Urbino are mentioned.
