Interesting Experiment with Flour.

A French chemist last year exposed a quantity of flour to hydraulic pressure of 300 tons, which reduced it to a fourth of its original bulk, without impairing the quality. He packed a portion of it in tin boxes and sealed them up, doing the same with the unpressed flour. When opened in three months the former was in better preservation than the latter. When baked into bread the pressed article was decidedly superior. After the lapse of a year other cans were opened and the unpressed flour had become spoiled, while the pressed remained sweet and was excellent when baked.
