12 THE LARKSPURS AS POISONOUS PLANTS. 



vivisection work, and this introduction is indorsed bv Lohmann's 

 work.'^ 



Schiller '' corroborates Lohmann's results, but claims that curare is 

 efficient for muscle physiological work in smaller doses than is the 

 delphinin of Heyl. 



This use of Delphinium certainly offers a field which should be 

 investigated commercially, as curare is likely to be uncertain in its 

 action." Methyl delphinin is said also to possess this curare-like 

 action.** 



The coloring matter of the flowers of Delphinbon salil has been 

 utilized as a dye.*" Other Delphiniums, such as D. ajacis, have been 

 recommended for insecticidal uses, and especially on account of 

 cheapness.^ 



Froggatt states that common garden larkspur vrill kill locusts, and 

 advises planting them in masses around gardens and orchards to pro- 

 tect against the ravages of these insects.^ The same claim is made 

 as to its action against grasshoppers.'' 



Delphinium coeruleum has been used to kill maggots and D. hruno- 

 nianum to destroy ticks.'' This latter plant has been used to some 

 extent as a substitute for musk.
