POISONS. 181 



Symptoms: Chronic diarrhea, gradual emaci- 

 ation, and sometimes a short, hacking cough is 

 present. 



Treatment: Change of food and water. Iron 

 sulphate in small doses twenty grains per day 

 may be given. 



Postmortem appearances: Paleness of mem- 

 branes with a general hydremia. Sometimes the 

 postmortem findings are very obscure. 



5. Phosphorus Poisoning. 



This is sometimes seen in sections where this 

 poison is used to kill noxious animals, such as 

 squirrels. It usually occurs in the acute form. 



Symptoms: Phosphorus poisoning greatly re- 

 sembles arsenic poisoning in that there is great 

 salivation, a staggery gait, and death from con- 

 vulsions. 



Treatment: One dram copper sulphate (blue 

 vitriol) dissolved in a pint of water; same dosage 

 of potassium permanganate; one tablespoonful 

 turpentine given in mucilaginous solutions neu- 

 tralizes the poison, changing it into phosphoric 

 acid. Peroxid of hydrogen, lime water, charcoal, 

 and raw eggs are also very useful. 



Postmortem appearances: Very similar to ar- 

 senical poisoning. In subacute cases no lesions 

 may be observable, 



6. Copper Poisoning. 



Symptoms: Colic; diarrhea; weakness; slow, 

 wiry pulse.
