almost invariably ulcerated. Fanners often look ui)on tlie separation 

 of tlie niucons lining' of the rumen as evidence of poisoning', but such 

 is not the case, unless the tissues underneath are iiifiamed. l"'he

if tlie animal has been sick for several days before death tlie 

 liver lias a macerated ap])eai'ance. 



To ascertain for cei'tain whether an. aninutl lias died from the 

 efi'ects of arsenic, fluid from the fourth stomach and small intestines, 

 with a piece of fiver, should be forwarded to an analyst with inslruc- 

 iions to test for arsenic. 



Treatment. 



'^^I'he best chemical antidote is ferric hydrate. I'll is may be pre- 

 [laied by diluting three ounces of tincture of jjei'chloride of iron 

 wiih four ounces of water; dissolve one ounce of caibonat(> of soda 

 (washing- soda) in half a i)int of water; mix the two solutions and 

 administer. These quantities will render insoluble ten g'rains of 

 arsenic. Three doses at least should be given, repeated at intervals 

 of a quarter of an hour. The above doses are for horses and cattle. 



In animals the diagnosis can rarely be made soon enough to 

 give the chemical antidote a chance. To be of any use it must be 

 administered within a very short time after the poison has been taken. 



If the chemical antidote is not at hand, or if the poisoning has 

 not been discovered until several hours have elapsed, the best line 

 to adopt is to try and allay the corrosive action of the drug by 

 administering demulcent drinks, such as well-boiled flour or oatmeal 

 gruel thinned with plenty of fresh milk, together Avith sedative 

 medicine, such as tincture of opium or chlorodyne. The dose of these 

 drugs for full-aged horses and cattle is from one to two ounces accord- 

 ing to size, and this dose may be repeated every six hours whilst the 

 pain and diarrhoea continue. The subcutaneous injection of four- 

 grain doses of morj)hia in the first stages retards absorption of the 

 arsenic, and in later stages relieves the ])ain and inflammation. 

 Purgative medicines are contra-indicated. 



As external dressings to the skin wdien it has been scalded by 

 dip, soothing applications should be applied, and one (if the best is 

 carron oil, made by shaking together equal parts of lime-\yater and 

 linseed-oil. Lime-w\ater is made by adding a piece of quicklime about 

 the size of a w^alnut to a gallon of water; shake it thcu-oughly, then 

 allow the undissolved lime to sink and pour off the clear liquid.
