quantities of the toxic principles have already 

 been absorbed. 



Large doses of potassium permanganate, one 

 dram or sixty grains dissolved in a pint of water, 

 may be given. The triple sulphocarbolates, in 

 sixty grain doses, combined with a dram of tinc- 

 ture of ginger and an equal quantity of dioscorea 

 may also be tried. 



If only camp remedies are at hand, give a tea- 

 spoonful of powdered ginger, and one-fourth 

 teaspoonful each of salt and pepper dissolved in 

 a pint of lukewarm water. Teaspoonful doses of 

 turpentine in raw linseed oil may be tried, but 

 in cases where there is great inflammation of the 

 mucous membranes of the stomachs and bowels, 

 this seems to make matters worse. Raw eggs 

 are always valuable in soothing this irritation.

Botanical name Stipa. 



While over a hundred varieties of this grass 

 are known to botanists, only one, "Sleepy Porcu-

 Mexico. It grows at an elevation of from 5,000

 to five feet tall, with peculiar long, flat leaf -blades, 

 hence the name "porcupine grass." The stalks 

 and leaves are bright green, and the seeds very 

 coarse.
