POISONS. 193 



group to which the clovers and alfalfa belong. 

 None seem to be poisonous until reaching ma-

The most common lupines are rather tall, with 

 branching forms. The leaves are green above and 

 silver-grey beneath. The flowers vary from blue

Treatment: The potassium permanganate and 

 aluminum sulphate drench may be given. In cases 

 of convulsions, laudanum in teaspoonful doses, or 

 chloral hydrate in two-dram doses, or one-quarter 

 grain morphin hypodermically, may be adminis-
