Copper sidpliate jwi'soning, in its ciironic form, from grazing neai 

 smelting works, has been considered in the previous section. 



The tobacco plant is a narcotic;, irritant poison, causing gastro-enteritis, 

 convulsions, metastatic inflammation, contracted pupil, sweating, inter- 

 mittent pulse, diarrhoea, stertorous breathing, and stupor. Treat the 

 same as for opium. 



Sumach, or Poisonous Oak, is an acrid poison, causing gastro-enteritis. 

 etc. Give oil, oi)ium and flaxseed tea. 



Lobelia is an acrid, narcotic jxjison, causing salivation, gastro-enteritis, 

 feeble pulse, convulsions, and stupor, (iive oil, opium and mild stimu- 

 lants. 



IV. Poisoning of the Skin. 



Vegetable poisoning of the skin is not an uncommon occurrence, from 

 the nose or lips of the aninial coming in contact with some noxious weed 

 or plant while grazing. There are many such plants, besides the poison 

 oak and white hellebore noticed in the i)receding section, such as poison 

 ivy (or poison vine), hemlock, St. John's wort, etc. The symptoms of 

 such poisoning correspond very nearly to those manifested in the human 

 economy from the same cause, and which every one living in the coun- 

 try is familiar with. The treatment is both constitutional and local, — the 

 former bj'^ the use of alteratives, together with such purgatives as may be 

 required to keep the bowels moderately loose ; the latter, by washing the 

 irritated surface with a solution of sugar of lead, or other cooling and 

 healing wash. 



V. Poisoning from Stings. 



In many sections, every farmer is lial)le, in the summer season, to 

 have his team severely stung by hornets, bumble-bees, or the like ; while 

 in the Southwest, the torture inflicted on stock by the swarms of certain 

 gnats and poisonous flies is fairly maddening. Then, too, a stock man in 

 the latter section is almost sure to occasionally meet with such urgent 

 cases as rattlesnake or tarantula l)ites, 



A homely remedy for the sting of liees, wasps, etc., is to wash with 

 salt and water ; and this is excellent, in ordinary cases. Onion juice is 

 another. For severe cases, it will be better to anoint the parts Avith a 

 compound of hartshorn and oil, — three parts of the former to one of 

 the latter; or spirits of turpentine and laudanum, in equal parts, will 

 afford relief. It will be a good idea, if the irritation is very great, to 

 sponge the whole body with lime water or a weak solution of soda, and 

 then smear with linseed oil. 



To protect against gadflies, wash the flanks and parts most likely to 

 be attacked, with a strong infusion of the green bark of the comraou 

 elder.
