Worm Iledicines. 149 



When worms are suspected, it is advisable to give a purge 

 and watch the feces. Should any parasites of either kind be 

 :found, it is appropriate to commence specific treatment.

 commends : —

Oil of male fern, 



Aloes, each 1 drachm. 



Ginger, 4 drachms.

Oil of male fern 1 drachm. 



Linseed oil, ^ pint.

 fuges in the horse is tartar emetic. He prescribes it as fol- 

 lows :—

Make into a ball with linseed meal. Give one every morning for a 

 week on an empty stomach, and then follow with a purge of aloes. 



After this he allows the horse to rest a week and then re- 

 peats the above, following the physic with a drachm of pow- 

 dered sulphate of iron daily in the feed.
