DROSERA ROTUNDIFOLIA. [Chap. VIII. 



AODS. 



I will first give, as in the case of the salts, a list of the 

 twenty-four acids which were tried, divided into two series, 

 according as they cause or do not cause inflection. Aftep 

 describing the experiments, a few concluding remarks will 

 be added. 



Acids, much diluted, which 

 CAUSE Inflection. 



1. Nitric, strong inflection; poi- 



sonous. 



2. Hydrochloric, moderate and 



slow inflection; not poison- 

 ous. 



8. Hydriodic, strong inflection; 

 poisonous. 



4. Iodic, strong Inflection; poi- 

 sonous. 



6. Sulpliuric, strong Inflection; 

 somewliat poisonous. 



6. Pbosplioric, strong Inflection; 



poisonous. 



7. Boraclc, moderate and rather 



slow inflection; not poison- 

 ous. 



a Formic, very slight inflection; 

 not poisonous. 



0. Acetic, strong and rapid In- 

 flection; poisonous. . 



10. rropionlc, strong but not very 



rapid inflection; poisonous. 



11. Oleic, qulclc inflection; very 



poisonous. 



12. Carbolic, very slow Inflection; 



poisonous. 



13. Lactic, slow and moderate In- 



flection; poisonous. 



14. Oxalic, moderately quick In- 



flection; very poisonous. 



15. Malic, very slow but consid- 



erable Inflection; not poison- 

 ous. 



16. Bentolc, rapid inflection; rery 



poisonous. 



17. Succinic, moderately quick In- 



flection; moderately poison- 

 ous. 



18. nippnric, rather slow Inflec- 



tion; poisonous. 



19. Hydrocyanic, rather rapid In- 



flection; very poisonous. 



Acids, diluted to the sahb 

 Degree, which do nut caubb 



Inflection. 



1. Gallic; not poisonous. 



2. Tannic; not poisonous. 



3. Tartaric; not poisonous. 



4. Citric; not poisonous. 

 0. Uric; (?) not polaonoas.
