SUMMARY. 



I. Milk vetch has been proved to be poisonous to cattle. 

 Suspicion is held regarding its effect upon sheep. 



II. Eighty to ninety per cent of the animals affected die. 



III. Water easily removes the active poison from green or 



air-dried material. 



IV. All parts of the plant contain poison with a slight ex- 



cess in the leaves. 



V. The poison is neither precipitated by basic acetate of 

 lead nor decomposed at the boiling point of water. 



VI. It can be deprived of its toxicity by boiling with dilute 

 acids (indicating its probable glucosidic character). 



VII. The poison is non-alkaloidal. 



VIII. A definite crystalline substance has been isolated, giv- 

 ing chemical reactions common to glucosides. 



IX. Thus far no chemical antidote has been obtained. 



X. As indicated by the physiological action of the poison, 

 drugs that stimulate the heart and nervous system 

 should prove beneficial in the case of vetch-poison- 

 ing.
