Sodium, Carbonate of (pure, given me by Prof. Hoffmann). 

 Half-minims (.0296 c.c.) of a solution of one part to 218 of water 

 (2 prs. 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 unaf- 

 fected. But the dose, though only the j^^ of a grain (.135 mg.), 

 was evidently too strong, for three of the seven well-inflected leaves
