 spection of the stomach and bowels. The inflamma- 

 tion brought on by either of these mineral poisons is 

 much more rapid in its progress, and produces more 

 pain and distress, than the infiammation from other 

 causes ; and the stomach, on being opened, is found 

 more highly inflamed at one part than another. It 

 will have partial spots of inflammation, and the viU 

 lous folds of its inner surface will iiave gangrenous 

 and ulcerated spots on it. The intestines will also be 

 fbund highly inflamed on the inter surface, and with 

 similar gangrenous specks ; an appearance not ob- 

 servable in other inflammations : they will be filled 

 also with a thick bloody mucus. In cases where sus- 

 picion of this kind arises, some of the contents of the 

 stomach and bowels should be jjut into a phial, and 

 which should undergo a chemical analysis by an ex- 

 perienced chemist, who, in case of any remains of 

 poison being present, will be able to detect them. 



Som.c times, from paint being left about, dogs will 

 iick it. When there is lead in it, the effects are stu- 

 pidity, dislike to food, irregular pains in the bowels 

 that make the dog scream out by fits and starts, and 

 there is generally costiveness. After death, evident 

 inflammation appears, particularly of the bowels, 

 and the inflamed parts appear in patches, but not in 

 spots, as in arsenic or corrosive sublimate ; nor are 

 the appearances of gangrene so considerable. 



But the most common poison is the vegetable 

 called crow fig, which produces its deleterious eflects 

 bv robbini? the nervous svstem of all its enenrv in a 

 few minutes. In a case, of madness I have seen a 

 very strong Newfoundland dog destroyed in five 

 miimtes and a half bv a dram of this substance ; and
