Puzzlement

"I remembered also the necessity imposed upon me of either journeying to England, or entering into a long correspondence with those philosophers of that country, whose knowledge and discoveries were of indispensable use to me in my present undertaking (page 110)." One thing I do not understand is this. Why does Victor really have to travel to London? At this point, it seems reasonable to conclude that no one else has created a human being like he had. Also, it is not as if the creation wanted a new and improved woman creation. He wanted one like himself, so Victor knows how to create one already. If the creation was at all concerned with it being a new advanced version, he would no longer find comfort in the woman. He wanted someone to look and act like him so that he would not have to feel as bad about himself. If the woman was improved in appearance, then she would likely find him disgusting, as well. This would defeat the purpose of her creation.
