In Sextons version the queen wants the heart of the princess, but in the Grimm Brothers she wants the lungs and liver. The reason for this change could be that the heart symbolizes life and the queen wants to take Snow Whites life away so no one can be more beautiful than her.Another difference is how long it takes Snow White to reach the Dwarfs cottage in the woods. In the Grimm Brothers version it only takes Snow White around a day to reach the cottage. In Sextons version it takes the princess seven weeks to reach the cottage. This could be better to better represent how long it would actually take for a little girl to cross seven mountains. In the Grimm Brothers version Snow White is humble and polite. She only eats a little bit of food off of each little plate because she doesn't want to upset the Dwarfs who life in the cottage in hopes that they will let her stay there. In Sextons version Snow White is more greedy than that. She eats each each chicken liver, fully, off of all of their plates. I believe this is the first evidence in this version that Sexton is trying to change the character of Snow
