TOXICOLOGY. 363 



There is great prostration and gradual loss of conscious- 

 ness in severe cases, followed by death. 



YEW-TREE FOLIAGE. 



Many instances of death from browsing on the leaves of 

 the yew-tree (Taxus Baccata) have been recorded in the 

 horse. 



After death, which in some cases took place from two to 

 three hours after the ingestion of the foliage, the stomachs 

 were found contracted and inflamed. 



Method of Detection. — Fragments of the leaves or the 

 berries may be found in the stomach after death. 



The apex of the leaf of the yew is not so pointed as 

 that of the savin ; and the yew-leaf does not possess the 

 peculiar odour of savin when rubbed. 



Yew-berries are of a bright red colour, and green at the 

 top, allowing a hard brown kernel to be seen. 



The juice, which reddens blue litmus paper, has a 

 nauseous sweetish taste. 



Treatment. — The method of treatment to be adopted is 

 the internal administration of oleaginous purgatives and 

 diffusive stimulants, such as the aromatic spirit of ammonia 

 and nitric ether in linseed gruel or water. 



CORROSIVE SUBLIMATE

 appetite, salivation, pawing, looking at the flanks, rolling, 

 profuse perspiration, rapid, weak, tliready pulse, violent 

 purging, tenesmus, convulsions, and death.
