What did Wittgenstein have awareness of, when he came back to Cambridge in 1929? --This historical question is the topic in this paper. In other words, it is the problem on his turn from 'Early-' to 'Middle-Philosophy'. Although various approaches can be considerd, I take notice of 'notation' in "Tractatus Logico-Philosophicus", and put it on a central problem in this argument. Interpreting that his distinction between 'Logic' and 'Mathematics' in "Tractatus" is starting-point in his Middle- Philosopy, we can make a well-sighted historical reconstruction.
