Dorothea in Middlemarch

Hello everyone !

First of all, I would like to apologize if my english is not perfect, given that I am French.

I would like to make a presentation about women in the british literature, and I want to talk a little bit about Dorothea, a character of the novel Middlemarch, which was written by George Eliot.
Do someone know in which chapter Dorothea announces she wants to marry Ladislaw ?

Thank you all !

Not off hand. Why can't you just look it up in the book?
