G06 SYMPTOMS OF POISONING BY SULPHATE OF LEAD. 



tion or colic, as in the human race. lu a few days death followed. If 

 the injured beasts were removed to another farm they never throve. 

 In the young the symptoms were more conspicuous and the mortality 

 greater. Lambs were yeaned paralytic ; when three weeks old they 

 could not stand, although they had made great efforts to do so : in 

 attempts to feed out of a bottle they were nearly suffocated from 

 paralysis of the glottis, and twenty-one died early out of twenty-three. 

 Colts also died ; and those that lived could not be trotted 150 yards 

 without distressed breathing. Pigs confined to the stye were not 

 injured ; but if allowed to roam were soon affected. The milk of cows 

 and sheep was reduced in quality and quantity ; and cheese made from 

 the former had less fat in it. I find in the milk of both minute traces 

 of lead. It will be observed that of the symptoms, those of emaciation, 

 paralysis, and the blue line in the gum of the lower jaw, are similar to 

 those of the human subject, that constipation and colic are absent, and 

 that we get two new ones — shortness of breath, and swelled knees."
