Sodiwm, Carbonate of (pure, given me by Prof. Hoffmann).—Half- 
minims (0296 c.c.) of a solution of one part to 218 of water (2 ers. to 
1 oz.) were placed on the discs of twelve leaves. Seven of these 
became well inflected; three had only two or three of their outer 
tentacles inflected, and the remaining two were quite unaffected. But
