156 VETERINARY TOXICOLOGY 



pest in the western province of the Cape, and that, being 

 dangerous in the withered condition, it gives rise to acci- 

 dents through becoming mixed with dry forage — e.g., at 

 Kimberley. 



Active Principle. — The chinkerinchee has been studied 

 by Power and Rogerson,* who succeeded in associating the 

 toxic action with a dark green resin. This substance is 

 unfortunately indefinite from the chemical point of view. 

 No alkaloid was detected. Experiments by the Agricultural 

 Department of the Cape proved that all parts are poisonous, 

 and that the plant is very dangerous. 



Poisoning. — Walsh records dulness, depression, and loss 

 of appetite, followed by severe purgation, with severe 

 abdominal pain, or a drugged appearance. Horses go off 

 their feed, but drink copiously. The purging continues, 

 the evacuations becoming fluid. The eyes are staring and 

 glassy, and heart affected, the beating being abnormally 

 loud. Violent struggling, kicking, and flow of foam and 

 mucus from the nostrils may precede death. 



On post-mortem there is found much gastro-enteritis, the 

 blood thick and dark, and alimentary contents fluid and 

 stinking. 



In treatment, sedatives (laudanum) and oily purges are 

 given with ammonia, spirits of nitre or brandy against 

 weakness. Alkali, such as bicarbonate (| ounce), is stated 

 to be valuable. 



Tulp. 



This order includes, according to L. H. Walsh, the South 

 African ' tulps,' distributed throughout the country, some 

 having been introduced from Australia, where their dan- 

 gerous character had been noted. They thrive in various 

 localities — in sandy soil, in vlei lands, and on hillsides- 

 Tulp is frequently a prominent plant after the first rains on 

 burnt veldt. Three species are specially noted — viz., Groot 

 tulp (Homeria colUnia), Klein tulp (Moraa sp.), and Blauw 

 tulp {Morcea sp.).
