1. Rice and barley plants grown in the fields contain very large amounts of silicic acid as the following analytical results show : [table]2. When the rice seed was unhulled before sowing, the seedlings grew very poorly in the culture solution, but their growth was so much improved that the seedlings appeared almost normal as the control plants by addition of a little amount of ground hulltissues or pure silicic acid in the culture solution. When the tolerable quantity of soil or sand was added in the culture solution, the unhulled seedlings grew almost normal. 3. The addition of colloidal silicic acid in the culture solution decreases the injury by cold for young barley plants. The silicic acid in the hull seemed, to some extent, to be useful as a nutrient for young barley.
