the viscera is relatively great, it is necessary, in order to 

 legally establish a case of poisoning, to prove that no 

 arsenical medicine has been given, that there has been 

 access to an arsenical preparation, and that the symptoms 

 and lesions are consistent with those of arsenic.

ANTIMONY. 



PFepapations. — The compounds of antimony do not find 

 much use in modern medicine. 



Potassium antimonyl tartrate, or tartar emetic, prepared 

 by boiling together antimony oxide and potassium acid 

 tartrate, is the most convenient soluble antimony com- 

 pound. Along with iron sulphate it is used as a vermicide, 

 and is recommended by Noel Fillers as very effective against 

 lumbricoids of the horse. 



The native sulphide, or hlack antimony, purified by 

 fusion or by digestion with ammonia, in order to free it as 

 far as possible from arsenic, is still extensively used in the 

 manufacture of the so-called ' condition powders.' These 

 contain about 18 per cent, of antimony sulphide, together 

 with nitre, sulphur, and a spice — e.g., aniseed or fenu- 

 greek. The old-fashioned Kermes mineral is a mixture of 

 sulphide with a little oxide. 



The oxide, which is colourless, is sometimes used as a
