Poisoning by Sulphur. 275 



Treatment. The mercury should be percipitated in an insol- 

 uble form and then eliminated by emesis or by the stomach pump. 

 White of eggs is usually the most available agent producing the 

 albuminate of mercury. This is, however, still soluble in acid 

 and alkaline liquids, in chlorides of potassium, sodium or calcium 

 and even in excess of albumen. Vomiting may be favored by 

 tickling the fauces, or by hypodermic injection of apomorphia. 

 This may be followed by boiled flaxseed or copious drinks of rain 

 water. When the mercury has been largely eliminated the sali- 

 vation may be controlled by chlorate of potash, and the digestive 

 disorder met by bitters and iron sulphate. 



Test for Mercury. Place a few drops of the suspected solution 

 on a clean surface of copper ; acidulate with muriatic acid ; then 

 touch the copper through the liquid with a piece of zinc ; a silver 

 colored stain will be formed .ea.sily dissipated by heat. 



POISONING BY SULPHUR. 



Fatal dose, horse 16 ozs. Symptoms : dullness, anorexia, colic, diarrhcEa, 

 sulphur odor. Lesions : congestion, desquamation, ulceration of gastro- 

 intestinal mucosa, sulphur odor in flesh, blood nearly fluid, blackens silver. 

 Treatment : chloride of lime, oil, puncture rumen or colon, stimulants. 



In excessive doses this is irritant. The horse is poisoned by i6 

 ozs. (Tabourin) : violent colics follow adoseof 12 ozs. (Collaine). 

 Cattle are less .susceptible. ' 



Symptoms. Dullness, anorexia, colic, pulse small and quick, 

 skin cold and clammy. Foetid flatus and profuse diarrhoea, are 

 marked symptpms. 



Lesions. Injection of the gastro-intestinal mucosa, shedding 

 of the epithelium, ulceration, and sometimes gangrene. Sulphur 

 is found in the ingesta and faeces and a sulphur odor is prominent, 

 not only in the bowels but also in the fle.sh. Tympany from H^S 

 is common. The blood is mostly fluid, and ecchymosis is shown 

 on heart, lungs and other internal organs. The tissues blacken 

 silver. 



Treatment. Chloride of lime, oleaginous laxatives, use trochar 

 and canunla for tympany. In pro.strate conditions give stimu- 

 lants (alcohol, ether).
